Spent formative years on annunciators in mines, refiners, power plants. Love the ability to utilize supply house and troubleshooting guides.
Thank you, your previous repair vids and my soldering skills fixed my daughter`s tv.....CHEAP! New board was 80 bucks +shipping....parts kit under 25 bucks with shipping! Jamee says thank you. Building all those electronic kits as a kid paid off, or I would have had to buy the board.
Happy to see you doing more trouble shoot & repair vids.
great camera work, crystal clear with explanations. you can't do much better than that unless you fix the tv's for me! too much fun for me to do it mysellf!!
Excellent video and troubleshooting! Thank you!
Love your videos dude you are simply the best repair guy on youtube - simple explanatory vids, good presentation skills, good english, annunciation and knowledge.
Plus you look a bit like Colin Farrell - ever considered a career as a celebrity double?
lol
I repair computers and used to design digital stuff but i have learnt a lot from your vidz, now i repair everything and throw nothing out now - Great video as always Tampa-t , keep up the good work.
Oh man....wanted to know result of this repair now!😅..... Glad I sub to your channel, & can’t wait till part 2❗️
Cheers✌🏻
Looking forward to part 2 👍😎🤠
Will be looking forward to part 2👍👍
Always look forward to seeing more new videos from you, great videos..
Good job sir.i enjoy your repairing techniques.Thanks brother
❤️ the video as always and can’t wait for the next video
I really love your vedios and I learn a lot from them a lot. Thanks
Awesome tutorial!!
thanks bro. Hey check out iLuvtrading, he's a great guy.
Very good video mate thanks to share it ,well done 👌
Thank you! Nice video!
Enjoyed this video Tampa, looking forward to Part 2 :-)
Thank mate
love the diagnostics video!
awesome, thanks
you may already know this on most Samsung you can confirm wheather the power supply or mainboard is at fault by unplugging the cable from the power supply to mainboard and plug AC cord in if the backlight comes on your problem is the mainboard if not then its the power supply service mode from remote is mute 182 power im a retired Samsung tech they still make the best sets on the market love your vids
Great tips, thanks David 👍
Hi, does this trouble shoot work with most brands of TV? I have a Philips which just quit on me and I'm gonna open it up tonight.
Terrific....keep it up...Thanks v much.
Fantastic. U are Mr Mac Guyver.
I like how he ended his video by simply saying “later,” very masculine for a young guy his age and maybe he could teach his generation something about that! Lol 😂 ;)
Killer video dude! Keep up the good work little brother!
Repaired a Phillips PSU this week. 90€ was the cheapest one I could find. Took me one week to source the failed regulator IC for the mains mosfets witch cost me only 5€ :)
I got a tv just like this one from a recycling center and turned it on and worked perfect, until smoke started to come out from it. Turns out it was the inverter board. I order one from eBay and now that tv works great.
Enjoy the repair vids. Just an observation you had the leads reversed in the ESR meter.
lol, don't drink and tech, but i took those caps out and tested again and got same results. thanks
Thanks
Hopefully you’re still answering questions here. I have a slightly different model, but with the same issue. I removed the back and there’s no apparent issues with with caps or anything, no bulges or burn marks anywhere. Mine has 2 fuses which I checked right away and sure enough one was burned out. It is the one right next to the power supply. I replaced it and as soon as I plugged back in it popped. I tried it a couple times and the fuse popped immediately, so I can’t get any further testing power. I do have a digital MM but I’m not well versed on how to use it. I’m at an impasse - what would you suggest I try next? Old tv so it’s not worth putting more than $50 or so into a repair.
Thanks for the videos , like watching them great info . The Atari 2600 comment is from way back , which I thought was funny because I actually still have my original Atari 2600 lol 😂
Great video. Very Informative. Do you have any videos of newer UHD TV's? How to disassemble and remove boards. (There aren't screws on the boards)
good tutorial video.
great video tutorial as always.
just about the remote, theres cases that the IR led will flash but the TV wont react,
this could be one of 2 things
bad IR reciever circuit on the tv
or
bad quartz in the remote. (the component that sets the frequency of the remote signal.
Thanks for sharing, great tips 👍
You mean PROBLEM can also be caused by REMOTE CONTROL, POWER BUTTON? OR INFRARED CONNECTION?? Been wondering about that...as SOLID RED Light, ALWAYS ON, when TV is OFF...n SEEMS, IF DEPENDS ON ANGLE of REMOTE BUTTON, HOW I PUSH IT, n HOW LONG I HOLD IT DOWN.... EVENTUALLY TURNS TV =(ON) ... OR INSTEAD To ONLY A FLASHING SLEEP MODE LIGHT, =[SLEEP MODE, NO SCREEN OR SOUND]! LIKE PLAYING RUSSIAN ROULETTE, EACH TIME!! Sometimes OVER N OVER AGAIN, I have to PUSH POWER BAR OFF= FEW MINS, + BACK (ON), & LEAVE FEW MINS AGAIN + IF SLEEP MODE AGAIN, THEN DO SEQUENCES ABOVE WITH REMOTE & POWER BUTTON ON REMOTE, FEW TO MANY TIMES, TILL TV, FINALLY COMES ON >>CORRECTLY!! IRRITATION ENSUES!!
But You Say Maybe Possibly Be the ***(REMOTE)?? USE MY INTERNET PROVIDERS >>REMOTE
Please more SIMPLE DETAILS ABOUT REMOTE + BAD QUARTZ?? IS A REMOTE CONTROL CIRCUIT BOARD?? IF DROPPED HARD, INTO HARDWOOD FLOORS, FEW TIMES, BE THE PROBLEM?? REALLY APPRECIATE SOME HELP TO DIAGNOSE PROBLEM, DUE TO (MY FUNDS SHORTAGE) TO FIX IT! PLS, SEE MY DETAILS ON TV GOING INTO (SLEEP MODE,0), BY REMOTE, N EVENTUALLY (AFTER POWER BAR, +FEW RESETS + RE- TRYS) IT COMES ON + WORKS CORRECTLY + FINE....BUT SO FRUSTRATED, TRYING TO TURN TV ON, NOT GOING TO SLEEP MODE, TILL EVENTUAL SUCCESS, OFF N ON POWER RESET SEQUENCE!! THANKS!
I really really LOVED your VIDEOS, question do you have any book or curse for beginners?
My LG 32LH 200C Where the lighting has struck and the tuner is not working but my crome cast is working ....I didn't still remove the TV to see if the Turner comes with the mother board or can only the Turner replaced ...thanks all the way from Sri Lanka
If Chromecast is working but tuner is bad then replace tuner or main board. You can find parts at shopjimmy.com or electropartsonline.com or eBay.
Thanks sir.
Nice
Badass video!
Thanks for the vid! I need some advice on an issue with a Sony kdl-60r520a. It was struggling to turn on past the red standby led stage and now the standby led doesn't come on at all. I've taken the following voltage measurements from the power supply board:
3.3sb=3.3
ACD=3.3
Power_on=3.3
T_con_12v_gnd=0
Reg_12v_gnd=0
Tcon 12v=0
Reg 12v=0.44
Bl_error=0.5
Bl_on=0
Pwm_dimmer=0
Do you know what the problem is?
My situation is, the backlight overall is fine all are bright I've been checked with led tester, but when turn on the power all backlight is not bright enough, the light is too low. What do you think? Is this power supply issue? Do i need replace a new motherboard?
hey need help have a LG55UH6030 with vertical lines what the fix for that what do you recommend
Without looking at the video I think it's a capacitor. Had the same problem with my 2010 Samsung LCD TV. Let's see if I'm right.
Update: I was half right. Should of expected the transistors have a short.
Yea I just watched your video how to fix a LCD LED tv with no power pt 1. Do you have the 2nd one done yet? I liked the video very much and learned a few things from it but I have a 40PFL4901/F7B with a power board number of BA5D22G0201. I bought a repair kit like you did but I don't know how to check the items you or what to set the multimeter on. Please let me know as soon as you get it done ok? I don't know how tp find a schematic on it or any info really. You have other video's that I want to see too.Oh yea that is a Philips TV
I LIKE YOUR VIDEOS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!DON.
Wondering what happened to part 2
👍👍👍
Nice!
I have a Sony XBR 800 TV on the power board is putting out the correct voltage until I plug it into the main board then the voltage fluctuates and I have no picture or standby light. What are your thoughts I'm lost
Do some late model TV's have a standby voltage of 2.7 VDC? Various vids all refer to a 5 VDC or 3.5 VDC. My newer Sharp only outputs 2.7, despite P.S. board replacement. Red LED, no startup....even upon main logic replacement.
Great video.
My lg 42" 3d TV doesn't turn on, instead it cuts off the fuse in the 3 pin plug of the power Cable that connects it to the mains. When the fuse in the plug is replaced, it blows it up once the TV is put on.
What could cause this?
How could this be fixed?
Thank you
Can u use any flat screen tv parts or does it have to be the same name brand tv
a couple of notes. confirmation of stby power should be ascertained by disconnecting the wiring harness that goes to the main board and checking if your 5v is now stable (load the line down if necessary), as your main board can easily be shorting your stby down. you can see your voltage switching, so there is a chance it isn't from the p/s, though i didn't see you esr the stby cap. :P
Yes, good tips. Thanks 👍
@@TampaTecHi Sir!
Can you help me fix my tv?
Model: LG 55LW5600
Standby power is good.
When you turn on the power, there is no display.
I check the voltages, Pin 1: POWER ON 24V is suppose to be 24V but I only measure 3.3V.
Which one is at fault the power supply or the main board?
Thank you.
Hope you can read my comment.
Okay so if the tv powers on but there is no picture possible could be bad t- con board you were saying?
I have a samsung tv I can really use your help trying to fix it can you help?
Where you been Tampa?
I was testing standby voltage on a Vizio M550vse on the main board plug the red stand by wire and a black wire I’m guessing is a ground?..and my Test lead touch the two pins and now the tv won’t turn on at all. Any idea were to check??
My Sony xbr-55X810C has same symptom. Lightning strike. Completely dead set. Power supply has 3.4 volts standby, 12.7 volts dc reg. but no 12 volts on TCON terminals. Several transistors are showing an unstable/varying voltage. Disconnecting the plug to the main board results in a loss of the 12 volt reg. and no back lighting appears. Any advise? I'm trying to decide what to replace first, Main board or Power supply.
My tv just shut off on me a couple of days ago. It's fairly old. Got it 2nd hand. There was already an issue with it when it comes to just turning it on. I had to hold the button occasionally to turn it on or when I hit the power button it took 30 secs or so for the tv to turn on.
At one point the tv was in standby. When I tried turning it on the light turned off and then went back into standby. So when I turned it on...I never turned it off again because I was afraid it would never turn back on....lol
I'm guessing my problem is most certainly a power board issue.
Side note the tv always seem to run alittle warm too. I guess an older tv (not sure how old) might run alittle warmer than new tvs.
Hello!
I have a Samsung lcd tv.
When I unplug the main board from the power supply board my screen turns on.
As soon as I plug them together the screen turns off. And I hear like a whizzing noise coming from one of the boards no quite sure which one.
Sometimes it turns on for 1min and off for 1min. While it's plugged in.
The power led light it's on when is plugged.
Please help me.
Thanks much for your video!
Good video thanks. I got same problem with my Samsung 50inch model ps50C530C1W just tripping of no standby light please can you help me to suggest the real problem? Thanks
Hi, May u please advise how much does it cost to change the display of a Samsung N5000 LED tv
Can this Samsung 55 inches TV with white dots be repaired?
Do they ship and cater to Australian customers?
I have a similar problem, my standby light is on but the tv doesn’t not power on. Everything works & slowly it started not turning on, eventually it didn’t turn on at all. Do you believe a power board will fix this issue?
I need a LS2204037-00-GP Power Supply Logik I cant seem to get one. Can I replace all the parts , if so, could you help name them on that board Thanks
Hi, can you tell me what can be? I have LG 47GA6400, i press power on and the small light start to light white and dimming off but nothing on the screen.
When checking the power supply and it indicates on the board +12 V and it shows 19 V is this ok?
Hello. I have a vizio D32X-D1 and the picture went out, but I had sound. I unplugged and replugged the power cord a few times, then lost sound too. When first powering on, the leds come on and go out quickly. I preformed the flashlight test and I’m not able to see a picture. Have any idea?
Guys am thinking to but a remote for this exact model do u guys think a remote will fix the issue
Can you please educate me how to solve the sound problem in LCD TV? It has good picture, there is sound, but the sound is distorting, rattling and its not clear. Is it a problem wtih the mother board? And pls also advise me if I can order universal motherbord for this and sort out the problem, Thanks
Can be bad audio chip or blown 🔊 but you need to test speaker to be sure. Watch this video from Shopjimmy it may help czcams.com/video/oC4f2Ik8rCI/video.html
What happened to part 2?
Where do you get your test equipment.
Amazon 😁 as always
Hey Tampatek, I have a found Nec v552 led flashes on then off. Red led flashes 3 times then..does the same. Do you think it’s a bad led? Power board is good and I baked mother board? Thanks
Your TV is flashing a trouble code. If you search your TV model online, you may find out what the code means....the table will be listed by number of flashes.
I have the same model as far as 50pg20 / us.ausnlhr but What’s exactly in the Parentheses? What is that?
Hi TampaTec! Great video Sir and lucky you for being in sunny Florida! Meanwhilst in icy Scotland................hoping yourself or someone can help. I was watching my LG TV, when suddenly the screen went black and the red standby light was pulsing for a few seconds before dying. I tried dusting, hoovering, removing the back panel and doing the same. However when I turn it on, the LG logo appears for a split second and the standby light pulses again for a few seconds before dying.
Any tips folks? I have read about baking the main board for a short term fix but am after something more permanent.
I have priced up a new main board, and power supply board, but am unsure which one it could potentially be and wondered if anybody could advise?
Baking board is only temporary fix if your lucky. But all those parts are temperature sensitive up to 160f / 71c. What you mentioned, I would buy cap kit for that tv model. Try eBay, or shopjimmy.com or electropartonline.com for tv parts.
Is it worth it if the screens are cracked.
Hi bro 😊
I have a TV of this model, telefunken tv te32269b40y2d
everything else is working fine but the picture is not coming, sometimes the picture is very blurry, what is the problem, can I open it and fix it at home?
What if your getting standby voltage.
Hi i got Sony XBR-75X850E tv just got 3 years ago, was working totally fine but all of a sudden today no picture no sound totally blank, only makes a clicking sound after every 5/6 seconds.can u tell me how to fix this problem ?
I've got a 52in aquos power light is green push power and just makes a click noise but no power to the screen
Sounds like bad capacitors, look for swollen capacitors.
@@TampaTec checked the power board all good the opc flashes twice and the power flashes 3 times on lc52d85u
@Blondie SL thanks for the help this model doesnt have any fans I found a main board online but the ver letter is different
before going through all that trouble make sure its not locked in standby mode because that disables all of the buttons on it when its shut off and resets will not work on it.
Didn't know what you were talking about. To Technical.
hi..may tv ist 50inch led ..no power no blink all capacitor end diode is ok..please solution
Hello .I have a problem with my 4k led tv 50” .I wish I can send you a picture , you see the problem.this problem started after I updated the firmware and it changed right at the installation and pictures and words doesn’t fit in the screen .when I switch to apps ,they are over others .like it’s not clear at all it’s like it switched itself to zooming and stuck there .I’ve tried to change the firmware to no avail. Please help .
I replace my power board and master boy and I still get a clicking sound what that's coming from is coming from the right corner or my TV on a 65 inch Samsung
Can you tell me your location I’ll
take my tv to you and fix it for me. My tv has no power
I think that you've already solved the problem. Replace the shortened component and replace all the electrolytic caps. And you won't have to purchase the new power supply
I opened my tv, its LG led tv. Red stand by light flashes 3 times and then nothing happens. Also, backlight just flash once and then it turned off by it self. On power supply board, I checked standby voltage , it is 3.4v. On the output side of power supply( lable mention four 80v pins and three 13.2v pins) when i check voltage on those pins i got 60.2v and 9.3v. Do you think my power supply is bad? Or i am not getting exact voltage bez tv is not turned on. Thanks
Don't trust those polarization marks even in good brand capacitors ! Sometimes they are wrongly labeled .
Which problem
l m leaning guys
I didnt no u can check volts on diode mode
true but fluke 113 meter has auto mode
I have a problem with my lcd computer monitor no power led indicator.can i send you a email with picture it is one module with power supply on board.
Afton LCD TV no power on
My LG has a steady red led, but will not turn on by pressing the button. I've attempted the rest set process several times with no success. Any one know of the right fix is.? I've checked the stand by voltage at the board and it exceeds the 13.2v .
I'm always surprised how many TVs I see when I go to the local recycler.
Did you take anything?
Hi
My Samsung LA37R81B has a blinking standby light and it's not switching the screen on. Can someone out there help to trouble shoot the problem?

Pls help me fix a Philips Led TV
Filipino repair of lg backlight
With voltages you shouldn't be using continuity on your meter. Nor to use it for transistors. A diode check works so much better. You need to read up on your meterminstructions. I'd rather trouble soot the circuit than to spend that money on foolish modules..it would be a lot cheaper..
