Let me know. What has been one of your favorite inexpensive or jerry rig repairs?
A repair of an older plasma TV that had blown capacitors. I think it was around $10 to repair the issue of it not turning on. My son still uses it - it's been about 4 years since I fixed it.
I repaired my relationship with my ex
I have a 65” Samsung where the bottom third of the picture is very dim and flickers. Can you direct me to one of your videos that would possibly address this problem? Love your work! Thank you
Thanks! Sounds like either a backlight issue or an lcd screen problem (or possibly a tcon board problem). My next two videos coming out will hopefully help give suggestions on things to try. I’m repairing horizontal lines and dark screen issues.
@@FrugalRepair ooh when's the videos releasing I'm waiting lol
Great video, Rhys! You make these complex issues seem so easy to diagnose and repair.
Thanks for the encouragement!
Hey there Reese. Thank you for all you do, for so many of us out here. The Clips that your channel produces are nothing short of awesome. Every one of your clips leave me sitting there, drooling a little and wondering Where fas your channel been all of my Life?! So, again I thank You. I myself have 2 LCD TVs that need help. One is a 43" VIZIO that is unwatchable. This problem occured at about One Year and a week old, of course. Anyway I took off the back and can see that a string of the LEDs are not illuminating. I just bought a new , Non-VIZIO, LCD TV. After watching you for a while, I think I may have the motivation now to attempt this repair myself. Thanks again. I also have a Samsung that is barely watchable. An Ex threw a glass of wine at it, but its issues appear to be similar to the VIZIO's problem, in that half of the screen is not illuminated? So I think I'll try this one as well?
Is there anything inside of these LCD TVs that I should waqtch out for? Like "High Voltage," or anything? Neither of these things are worth dying for or even worth a visit to the Hospital.
Love your Channel and Thanks again Reese. Keep Smiling...
Thanks for your kind words! Unfortunately, I can’t provide a lot of help detail here but I do have ideas in my top tips PDF. If the lcd screen is broken on the other one, there’s nothing you can do to fix it. But hope you can at least give them a try!
Your videos are amazing!
I wish I lived next door to you and could be your apprentice!! You explain in a way that anyone can understand. And your video and audio quality is beyond professional!! 👏👏👏👏👏 Well done sir!! Cheers from Rio de Janeiro, Brazil.
Thank you for your encouraging words! It would be fun to be neighbors.
Thanks for this. Had this exact same problem with the exact same TV (like you, somebody gave it to me for free). Did the same thing and worked like a charm.
That’s awesome!
I love to watch this type of easy tips to repair tv .Very informative video thank you bro
Thanks for the kind words!
So I found one of these TV's at the local GW for $40. Plugged it in to power and turned it on at the store, got a picture and thought all good! Got it home and plugged the cable box into HDMI 1and got the no signal message from all of the HDMI ports. Then researched the issue and came across all the sites that say cook the main board in the oven, wasn't crazy about the idea and knew the wife would not go for stinking the house up with the toxic smell of roasted PCB. Then I came across this video! Appreciate the way you explain why this method works and the time you take to preheat the board and protect the surrounding components with heat resistant tape. So I attempted the repair today following your method, even used an infrared thermometer to monitor the board temp. Results, beautiful working 47" TV in the bedroom for $40. Long story short, FrugalRepair, YOU ARE THE MAN!!!! Please keep those videos coming to keep all us DIYers out here inspired and on the right track. Thanks!!
Wow, way to go! I’m so pumped to hear that you got it working. Yes, more videos are in the works.
the secret to chip reballing at home is out! Excellent video!
Thanks! Though I didn’t actually reball the chip, but I think I know what you mean.
Worked perfect on my TV...Got all my ports up and functioning...cool trick on the light bulb underneath the board...thats always the problem when it comes to them chips..
Glad to hear you got yours working!
Excellent way of explaining good for the people who wants to learn
Thanks! I’m hoping it’s helpful.
Clever stuff. Back in the early 2010s, My business repaired broadcast & professional av equipment. We had a Hakko hot air station set up, worth around $15k, and used heating profiles supplied by the manufactures to remove and replace BGA and 150 plus pin ICs. Now I find out I could have just used a $150 heat gun and $1 globe!!! Brilliant stuff. I’ll have to give it a go on a HD capture box I have that doesn’t work.
Thanks for watching! With your experience I bet you can get it to work. Good luck!
Mate you're a legend. My Tv has got this issue. I leave my tv out in summer hot day Sun 🌞 for an hour or so and it will start working, but when I turn it off it cools down and doesn't turn back on. I'm going to try this method you have shown in this video. Thanks 👍
great video shows how to fix this problem,,, it's a big help for me,,, thanks Rhys,, watching phillipines,,
Thanks for watching!
Wow I learned a ton, good to know about the heat gun!!
Keep the videos coming I love them
Thanks! Several new videos are currently in production. =)
Had the same Issue but since I have a model with plastic covers on the motherboard, I put it in the oven at 90° only for 30 minutes and it worked aswell !!!
Good video. I ran a bga machine at my old job... sure wish I still had access to that thing. It was top o the line!
Thanks!
It worked!!! I did the hair dryer job and it worked today, 02/04/2021. Guys, I have a 42 inch LG LE5500 from 2010. All hdmi ports stopped working, so I disassembled and warmed up first for 1 minute and nothing. So I did it for 2 minutes and it came back ... but a little while it stopped again..then I did it for 2 more minutes and it came back. I tested it in the morning and now at lunch it was working ... well, the thing is, it worked. Tks for the advice and money saved
Great to hear! You’ll probably have to do it again at some point but it will keep it alive for now.
@@FrugalRepair to make sure I haven't closed the lid of the television yet, lol. Just to make sure :)
I'm going to do the same exact thing tommorow thanks for the tip I picked up 4 TV's with different types of faults luckily none had lcd damage thanks for inspiring me too look for free tv's on Facebook market place and keep me busy during the stay at home order lol
That is great to hear! Did you get my pdf? It may help you diagnose those TVs more quickly. Also, my next two videos coming out should help even more (hopefully!).
@@FrugalRepair I did and your PDF is full of great information! And ooh can't wait for the new video
Thanks for this awesome video. I really apprecaite it.
Thanks for watching!
I have an A.A.S. degree in Industrial Electronics and 23yrs experience in electrical maintenance......you by far, did an excellent job at this! I have a LGLX6500 LED 3D television that was a house warming gift from my late grandfather. The TV has sentimental value. I think mine has the issue that most do with that chip, "No Signal" but it lights the LEDS for power and the bezel LG logo, just no signal to inputs :-/ . It's hard finding these boards new at a price that I am willing to chance.
Thanks for your kinds words! Hope you can get yours working.
my new fave channel
Cool! I’m working on the next few videos and they’ll be coming out soon. Let me know if you have suggestions on what kinds of things you want to see/learn.
I like your videos, your way of talking and more over your smiley voice ❤️
Warm wishes bro
Thanks for watching!
Awesome video.
Thanks for watching!
All 4 HDMI ports stopped working on my 12 year old LG 60PM6700 3D Plasma TV so I baked the main board at 390F for 15 minutes and all the HDMI ports now work.
this is very well done brother!
Thanks! I hope it will work to catch up in person sometime in the not too distant future.
@@FrugalRepair likewise!
Great fix my friend 👍 and nice to see a friendly face. Keep up the great work. Kind regards. Paul.
Thanks, Paul!
@@FrugalRepair your very welcome. I repair vintage audio gear. I hope you and your family are well. Kind regards. Paul.
Very well put together video. Definitely a step up than the average reflow video. I reballed one of these LG's with input issues with leaded balls. But it ended up failing again 6 months later. It might be internal chip bond wire issues and not a BGA issue.
Thanks! That’s interesting. Could it also possibly be a warped pcb or chip causing the solder ball to lose connection?
@@FrugalRepair I suspect internal chip issues. Common with flip chips, the bonding wires break internally. The heat during rework causes flexing and exspanes/contracts. Making the bond wire touch again. Often mistaken for BGA issues.
Thanks. Do you know if this chip is a wire bond or a flip chip?
@@FrugalRepair pictures sent. Check your email.
@@jeffescortlx Thanks. That seems like a different chip than the one I worked on this this video (Broadcom vs LG). But maybe it's just the branding. Anyway, the flip chip vs wire bond is how the die connects to the external chip pads. You won't be able to take a photo of it unless you take the chip apart. Great job on the reball, BTW!
that is amazing ! so many high tech equipment though. a regular person wont be able to acquire all those.
well done &thank you very much
Thanks!
impressive what you did there
Thanks!
Thank you very much I was able to fix my TV
Awesome,congrats!
Great job 👍A+ most people think heating alone works but do it wrong so the chip only works within few weeks. Flux is key to make reflow fix last longer. I think Xbox 360 GPU failed because unleaded solder used. I recommend leaded solder.
Thanks, Paul! There’s also a misconception out there with the 15” and 17” 2011 MacBook GPU’s. The issue isn’t actually the solder underneath so the “reflow” will be hit or miss. There is a problem inside the chip and unfortunately the chip needs to be replaced.
Tampatec your a great guy 2 my friend seen alot off your vids to m8,so i learned from u2,Thx and God Bless...
One of my favorite youtubers on recent memory, got me inspired to try tinkering with electronics myself !
Always great to see you making content boss!
Thanks, man! That’s encouraging to hear. Let me know what you plan to tinker with.
@@FrugalRepair Definitely TVs, smartphones and video game consoles
it's help me alot...
My son just found your channel, and now he is binging the videos! We have a Vizio E320VP someone gave us, and it powers up but gets stuck at the Vizio logo on the screen, and then does nothing. The only way to turn it off is to unplug it. From reading it might be the EEPROM but that seems like a tight fix for someone who has never done it. Probably will try to replace the main board as a whole and see. But we both have been learning!
Thanks! Next video should be coming out soon - a fun repair and result =). Yes, I would agree that you seem to have an eeprom issue. Maybe you could find a friend to solder it on for you? Or maybe a local makerspace club could find someone to do it for you? And of course, you can just replace the main board.
@@FrugalRepair Well I am sure my husband could do it if he could find some time. He is pretty good at all that, he built his own racing quads and remote plane stuff. I didn't think we could replace just the tiny little parts on the board until we bumped into your video. Worth a shot I guess. :). Looking forward to the new videos!
The third time around I followed your procedure and so far so good. Thanks for posting. The first 2 times I used the bake-board-in-the-kitchen-oven method, the first time it worked but lasted less than 2 months, the second time I set temp temperature a little higher and components fell off the board. Lets wait and see how long it lasts for.
Did you solder components back on the board? Or did you get a new board for the third attempt? Glad to hear it’s working!
@@FrugalRepair I got a used board from ebay
Did the same operation twice on an old LG 60" plasma TV and it served me well for 5+ years until It finally gave up with another error last summer and I threw it away. But yes, It´s sad to see that so much stuff is thrown away because simple faults... Forgot to mention, I got the TV for free from a friend since the HDMI-ports were not working =D
Thanks for sharing! That’s great to hear you got so much use out of it.
I got this TV for free recently as well! Now we'll see if I can correctly reflow the chip
pretty cool....any idea if it's still working?
I have this exact model TV and am having this exact issue, no HDMI input ports working regardless of what I try. I have had this TV for nearly 10 years now, and contacted LG to see if they would do anything about it. I know TV's are dirt cheap these days but it's the principal of the matter, seeing if LG will give me anything for my "troubles" ;)
By golly you've done it again! Now I just need one of my tv's to break to try it! *fingers crossed* lol. Great content!
Thanks! Actually, maybe you want to get your hands on a broken TV that’s better than one of your TVs and fix that one. Then sell your other ones.
@@FrugalRepairya I'm not leaving my house right now. Lol. It's OK though most of my tv's are vizio's Last time I had a broken TV, my dad stepped on it with steel toes while helping me move. I don't think that in particular can be fixed for under a dollar.
But next time I have a broken one... I know who's videos I'll check first.
Awesome video! Can I still do this without the thermal sensor?
Thanks! Yes, you can. You need to be careful that you don't over cook the board. So with a heat gun, say give it 3 minutes of close rotating heat on the chip. Then test it. You can try it again if it doesn't work and lengthen the amount of time. If you can see the solder get molten, that's when you know to stop but it's hard to see under the chip.
You are really something... 👍👏👏👏👏👌👌👌👌👌
Thanks!
Hey, I got this exact TV but the 42” version, I bit the bullet and had a go using my wife’s crafting heat gun. I used some insulating tape to hold down the small components near the main chip and then put a bit of cardboard on top with a small square cut out showing just the main chip. I then applied lots of heat and thought I had over cooked it perhaps as when I stopped and removed the cardboard some of the insulating tape had burned a bit. I then put the board back in the TV and connected up all the cables, the 2 thin ribbon cables were tricky. Upon powering on the TV came on but the screen was messed up, so I disconnected and reconnected the thin ribbon cables and after a good bit of fiddling and adjusting the ribbon cables hey presto screen working as it should and all HDMI working! Perhaps you could do a more detailed video on how to disconnect and reconnect those thin ribbon cables correctly as it probably took me 6 to 8 attempts to get then aligned correctly. PS: this is the 2nd time my TV has failed with the HDMI port issue, it failed after 4 years and was covered by the warranty and then failed a further 4 years later!
Great job on the repair! Yes, sometimes those connectors can be a little tricky.
how long does that repair last? I have seen in other channels that it is only temporary, however nobody does it as well as you have done
Had success with no flux just yesterday hope it holds up
It was a 50 inch 4k still working
thumbs up, thanks
Thanks for watching and the thumbs up!
Super!
Thanks
@frugalrepair I subscribed to your channel and I love it. But the LCD repair tips PDF was never sent to my email. Any chance you can fix that?
Sorry to hear! Send me and email (it’s on the about page or my website) and I’ll look into it.
I guess I have to try this on the BT chip in my PS3 which stopped working half a year ago.
Would not have been confident enough to try the heat gun without seeing it here.
Can I use docking station with hdmi ports and plug the DS USB to the tv USB port?
Thank you for sharing your knowledge. How does repairing a LED TV differ from repairing a LCD TV?
Thanks for watching! They are both LCD technology. The LED refers to the backlight. Older TVs used CCFL (fluorescent) bulbs.
@@FrugalRepair Thanks so much for letting me know this!
Hi, on my tv the coaxial port is not working, for over a year now, the weird thing is I conected it last week and it staeted yo work then it stoped, will doing this to the chip fix it? Thanks for the vid. Hope you answer
I have a TCL roku 55” tv barely a year old. The hdmi ports come back with no signal. It is out of warranty by 10 days. Do you have a fix for this? I enjoy your excellent tutorials. Thank you!
Thanks! I’m not sure if a newer TCL would have the same BGA issue causing loss of HDMI so I can’t say that I’d recommend the heat trick like I did in the video.
Plug in RCA Cable too, it's work for me :).
Sorry for bad English, GBU.
Do you mean use the RCA inputs instead of the hdmi?
@@FrugalRepair Use RCA first then Switch to HDMI, it's works for me, 3 HDMI port Normal back.
I have to do this to my TV (LG too) every 2 to 10 months. Instead of a heat gun, I back the whole board in the oven at 392 F for 10 minutes. I put it in a baker's parchment paper pouch and then into an aluminum pouch folding up the open sides to prevent the smells from escaping. It's annoying to have to do this, but it saves me $230 on a new board that is never in stock.
Have you thought about adding some active cooling? Like a fan to the back over the heat sink. They may keep it from warping again due to heat. You could potentially try something simple like cutting a hole in the metal cover to expose the heat sink. I have a big TV that I hope to work on soon and I might do the fan install and see how it goes.
@@FrugalRepair not enough room in the panel for adding a fan without modding the ,in my case, metal back panel. the only cooling I could add would be those little raspberry pi passive chip coolers. If you have a different idea in mind, I would definitely watch a video about it.
Hi Rhys I am interested in the heating process you used, because I need to change a processor platform on a motherboard. I do want to buy a heating plate for just one board, so with a few adjustments and a thermal imager with my heat-gun should work. What do you think?
Do you mean like a zif socket? You would probably melt the plastic with a heat gun. If you are asking about a BGA chip, then I'd probably not recommend doing an install of the chip with this method. It can be done but a rework station is the most precise. But if you want to give it a try, just be careful to not overheat the board and warp it.
@@FrugalRepair I am thinking of replacing the socket which has bent and broken pins on it. This motherboard was given to me because the original owner happened to accidentally bend the pins while changing the processor.
hi i have got a samung smart tv model number ue43tu7100k it has a line from side to side and i tryed doing what i saw on your vidio but it didt work any advice
Great but it could be very usefull if you can say how many minutes left the bulb after begin the process and how many minutes for the heat gun
How do you remove the heat sink?
Hi my tv have voice but screen is not on.screen have big broke line too.please help me.what issue it have.
My t.v. has a line with a white small dot in one place the line runs down the left of the inside of the screen is this caused by heat ir someone hitting it by accident
my vizeo can heat up my bedroom to runs hot from day 1 but its lasted 8 years now still works except for the sound.when it was new i could hear cracking noises as it heated up.now that its old it doesnt do it anymore
what kind of solder do you recommend?
It depends on what you’re using it for. I have leaded (for circuit board work because of the lower heat required) and nonleaded (in different sizes). I’m pretty sure I have solder listed on my amazon shop page.
I had a problem with my PC PSU and GPU, both are burned.
At same time both monitors HDMI inputs stop working.
It detects cable connected but there's no signal.
Could be a microfuse or a resistor burned?
The VGA input still working.
I had a lightning strike 10 m away from my outside TV aerial. Since then one of the HDMI ports on the back of the TV isn’t working. It was connected to a DVR recorder which was connected directly to the outside aerial. Is it possible that this would only take out one HDMI port or do you think something else calls the HDMI port to file?
Cheers Wayne
Yep, the surge could come through the hdmi. I have a video where this happened to a tv and I fixed it by replacing the main board.
How many minutes do i have to heat the chip
I am geeting no signals on my TV tuner (coax connected to HD TV Antenna). Would reflowing this chip could also fix that?
It could. Your problem could be caused by something else though. Sorry I don’t really know for sure.
For calling yourself Frugal Repair you have a lot of money invested in tools😂 I really like watching.
I didn't start that way. Any money I made from fixing things went into getting better tools. Having the right tools can save you a lot of time (and frustration).
In what time-frame would an "older LG model" be from? Thx
Like 2011 era. Maybe a few years before or after.
Hi, Can an infrared thermal scanner be used instead of a thermal imaging device? thanks
How is that different than what I used? I think it would mainly depend on the range and accuracy of the unit.
@@FrugalRepair It is a gun that has a 2-mm laser light that you point to the surface, to read the temperature. It does not have the advantage of thermal imaging where color uniformity on the chip surface can be seen at once. Instead, the laser beam should be moved on the surface as the heat is applied. -20 C - 520 C range.
It should work. Again, depends on range and accuracy. Also, you are hoping the laser is aligned with the thermal sensor. But it’s what I would use if I didn’t have a flir.
Wah,u seem wise
Im having this problem now with my 10yr old 32inch lg3dtv
I'm curious: Why didn't you use the oven method to reflow the solder?
For several reasons. I can’t measure the heat while it’s in the oven, its imprecise, it’s heating up the whole board which is unnecessary and could cause more problems, it melts the plastic which makes things stink, etc
Of course, I could know the heat on the dial of the oven, but it is very important to have a very accurate temperature reading underneath or on the chip so you can get just above the melting point and then stop. Oh, another reason not to do this is that you’re burning off flux, which is not something I want in my oven.
I have a Vizio 40" 4k ultra tv series D model D40U-D1 that will power on but I get no picture. I do get the V when it powers on, then the tv goes black. I tried the power unplug and reset options with no outcome of improvement. I carefully took the back off of the tv to see if I could notices any burnt or discolored resisters on the power board, but no luck. Any idea what I could do to get the tv working again?
Download my pdf if you haven’t already. I have steps in there to try.
Yea, did exactly as what was told in this video, now NOTHING appears on the TV screen, just pitch black while on. Thanks
Hey frugal! There’s lots of broken or cracked screens out there, could you try to repair one in a video? There’s not a lot of information out there
Unfortunately, you can't fix a broken LCD screen. At least, where the LCD is cracked. There are other tricks for other types of broken LCD display issues, like bad tab bonds, bad COF chips, etc.
The HDMI inputs on my 86" LG quit working after a lightning strike. The HDMI Arc output to the speaker bar still works however. What should I do?
You may want to check out my video on that topic. You can replace the main board.
This seems like a workable solution. I'm gonna try this on our church's old projectors. If anyone is curious about the result, leave reply here in the comments.
Are you going to heat the CPU? Have you seen elsewhere that is the issue? And it's not the bulb? I'm curious how it goes.
I'm curious as to your results
Do you know the possible fix to a TV that would turn on normally but once turned off it would have a hard time to be turned back on again, but once it turns on again it would work normally
That sounds like a classic symptom of bad rectifier capacitors on the power supply.
👌🏻
First of all, thank you for these useful videos. I finally bought a tv to repair after watching a bunch of your videos(Samsung UE46D5630). It has a good display which has a blue tint on-screen (HDMI inputs only; Other sources work fine).
I had a question I used your guide and it looks like my BGA needs to be reflowed as I get blue tint in all HDMI ports. The picture test is also good. I am planning too try this method but worce case will need to replace the mainboard(BN41-01587E BN94-05105S) which I cant find. any advice?
Thanks! Give it a try. eBay is where I usually go
Hey hope all is well....I've been holding onto my Vizio i701-a3 tv and still can't get it to work. I changed the tcon board and nothing....I had a repairman look at it and they said bad panel.... Please help me and where do purchase one of is it worth fixing
Unfortunately, your repairman might be right. One thing you could try is to disconnect one of the ribbon cables coming out of the tcon board and only driving 1/2 of the screen at a time. This is one technique I use to find a panel fault.
Hello. I did exactly what you said for my LG le8500. However hdmi ports still not working. Have you got any other advice? Should I increase the temperature above 200 degrees? Should I heat the another chip?
It’s possible you have a different problem. Are you certain no one has tried to heat the board before? For best chances you want to use flux and get past the melting point of the solder.
@@FrugalRepairWhen I reached 200 decrees I instantly stopped the heatgun. Should I continue heating at that temperature for a minute or two? I had the same issue twe years ago and I sent the board to an electronic service. Tha problem was fixed but it did cost me a lot and I do not want to spend the same amount of money again. Between the hdmi ports and the part that I see you heated, there is a small black chip with many external pins at all sides. I do not know its purpose but do you think that I should try to heat this also?
I wonder if they replaced the CPU chip when you sent it in for service. Did they say what they did? Hopefully they didn’t charge you to do what I did in this video. If your goal is to get the solder underneath to melt you probably need to get above 200°.
@@FrugalRepair No, they did not tell me what they did to fix the problem,. It is the official LG service and they told me that they use an expensive tool, that's why they had to charge me 120 euros. They warned me that I will face this issue again in some years. Nevertheless, I am not going back again. I will try again at about 210 decrees and hopefully the problem will be fixed. Thank you for your time.
That’s interesting that they told you it would happen again. If you do get yours working, I would advise installing a cooling fan over the heat sink.
I have a tv that looks like paint running down from the top of the screen all the way along the top. The guy said he laid it down to move and it started after that. Any ideas?
If the LCD isn’t cracked, then my first guess is that the connections to the driver boards need to be checked. The connections from the T con board can be reseated but unfortunately, if the tab bond connections were tweaked then things may be harder to fix.
Hello furgal, I have a question for you, hopefully you can help me with..... I have 7 36v batteries, I'm try to use a 36v to 12v step down, do I need 7 36v to12v step downs or can I use one step down for all 7 batteries......
Thank you for any help you can provide me with......
I assume you want all batteries in parallel so your starting with 36v? Or in series and starting with (7x 36v)? What are you trying to accomplish?
I'm tryin to connect them so the voltage will stay 36v, but the amp hr will change
Yes I want to start with 36v, but still have the amp hr for all 7 batteries, so can I use only one 36v to 12v step down or so I need one for all the batteries.....
I don’t know your application considerations but from what I remember in EE class that the 36v in parallel will stay at 36v so you would need one converter to get to 12v. Obviously rated for the correct amperage, etc
Love your videos something to bear in mind is time taken for most folks may outweigh benefits.
I have an oh tv which doesn’t have a tcon board
Hey how did u figure out that the problem is in the cpu and not on the HDMI ports themselves? Can't they get broken as well? How did u know it's the former and not the other basically
I guessed because it’s a common issue. Usually not all hdmi ports fail if it’s not the controller chip or cpu (or bga issue)
If the solder connections are between the chip and the board, why not heat the board from the bottom of the board where you can access the solder?
The solder balls are not on the other side of the board. It is possible to heat from underneath (I’ve done it before) but heating the chip from above is better in my opinion because gravity is on your side.
you have a quick 861d behind you lol
My hdmi port on the side of my LG tv broke off. Can I resolder it back on
You should be able to.
I fixed a Playstation 3 with the red light of death. A heat gun and some thermal paste fixed the problem.
Sweet! Great job getting it running again.
Hi my son broke my LG hd tv is that any easy fix how expensive can that run
If the lcd screen is cracked, then it can’t be fixed, unfortunately.
Hi FrugalRepair, it’s your tv still working? Thank.
As far as I know, it was a friend’s tv
i have a 47 inch vizeo heavy first lcds it still works amazing but sometimes sound will start crackling if i shut it off for for 15mns its fine or just ignore it it starts working normal been that way for 3 years its weird
That makes me think it’s related to heat or a bad capacitor. Glad to know you have a work around at least.
@@FrugalRepair Thanks!
All my 49 in LG TV functions work except HDMI ports. Replaced with new main board, HDMI ports still say no signal. Checked with known working cable and device. Any help appreciated.
If you replaced the main board, then they should be working. Maybe you can ask the seller you bought it from if the HDMI ports were tested ahead of time
I have a 46 inch Samsung tv that shuts off on its own what part should i buy?
You probably have to open it up and do some tests. Did you download my pdf? I have some tips in there you may want to look at. If the TV is older it could be bad capacitors on the power supply. Or it could be bad LEDs
Woah, I have that same yoda puppet, think his copyright date is 1980?
I think it’s that old. That’s fun. I was wondering if anyone would recognize the puppet. Did you see the late night show in the 90’s when they used this doll, pulled the ears back and it looked just like Barbara Bush.
is there any danger of heating the chip too much to cause damage?
If you have no feedback on temperature...yes.
