- Hi, I have no experience with TV repair, but thought I'd have a crack. I used the box as a table and did this solo. Sorry I forgot to turn my phone sideways. If you're planning on attempting this repair, you may find this useful.

Amazing work...outstanding considering the size of the TV!!!
So far watching this video has convinced me to never buy a 75 inch TV. Ever. That said, really good video. I learned a bit from this about how to tackle a project like this. How big that TV is, definitely presents a challenge. I think, the biggest thing would be to just start with the beer, off the bat. It, definitely, looks like a necessary tool in the completion of this repair.
Smart as an Egyptian and the Pharaoh, to begin with!
I had the same error. Without your video i probably never started to repair the TV. The new LEDstrps were different to the old ones. I replaced all LEDs. Thanks for your video. IT saved a lot of time. It took me only a half day. :-)
I'm glad this video is helping people. 1/2 a day is fast! did you do much differently from me? (apart from not melting the diffuser).
@@michaelclift6849 I used a thin knife made from a plastic bottle for the background paper (diffuser) and a thin real cutter for removing the LED strips. Other stuff was nearly the same. But you showed me what was next to do. I was running your video all the time during the repair. Thanks again.
@@marcusbode5353 ich nehme mal an du bist deutsch? Wie hast Du das mit dem Panel gelöst - genauso? - oder ggfs. Umgedreht und mit Saugnäpfen „ausgehoben“? Danke für eine Rückantwort!
@@prAsco servus, ich habe die Reparatur gerade am 65er hinter mir :) Respekt an das Video. Ich finde es umgedreht mitm Display oben definitiv viel leichter, ausser dass man mainboard usw vorher entfernen muss. Das Display kannst du ganz einfach mit griffen aus transparentem paketklebeband rausheben. Mehrfach über Kreuz 4x einen "griff" aus dem Band aufkleben
@@Fisch1986 Servus - hab mittlerweile schon drei repariert - zuletzt innerhalb 2,5 std mit dem Tausch aller led s. Hab mir Saugnäpfe gekauft und spezielles Klebeband für die Stripes. 👍🏻
Thanks for the video. I will start my Sony LED replacement soon. I love my TV. I hope I can do it too!
I would reccomend going as slow as possible, and putting as much thought into every step as possible. That's basically what I did. I'm no expert, but If you get stuck or have questions don't hesitate to ask. Good luck!
@@michaelclift6849 Did you "ground yourself?" I'm trying to do this right! LOL no disasters here! Thanks for your support.
@@cathy9791 I didn't, but I don't really build up static on my carpet. Maybe just take your shoes off.
@@michaelclift6849 I just replaced the LEDs. I found a small piece of COF? tape (looks like PCB tape) on the floor from the side . Is the TV junk now? I haven't plugged it in yet. Doing bezels.......
:(
@@cathy9791 COF? PCB tape? I'm not sure what you mean, but if it's just tape it's probably fine.
🤤 Frothing at watching this.....
funking good work sir, splendid job..
Thanks, apart from melting my diffuser, still I got there in the end.
I finally stripped my bravia KD-65X7052 today, after it wouldn't turn on, flashing red 6 times; this is almost always a backlight issue with Sony TV'S, so I'm told.
I'm finding LEDs almost impossible to find anywhere. Even the part numbers on the actual LEDs themselves bring back nothing online in terms of stockists.
Two year old TV, bought for £1,000 - and something as ridiculous as a BULB failing may see it being thrown in a skip 😔
These tv's are clearly built to fail, as repair is a crazy process. The TV shop I rang last week basically said that they'll attempt repair, but if they break the screen during removal, they don't accept liability 🤔
Hence I stripped it myself... Although I'm none the wiser for it 😕
Did you try complaining to Sony? Sometimes the squeaky wheel gets the grease. As for the leds, I would query the sellers of other backlight led kits. They may know which kit is compatible with your tv. Failing that, there are second hand parts available, but who knows when they will fail again.. www.ebay.com.au/itm/334298377677
Hi. Michael. When you moving using your phone in horizontal position. Try and make comparation.
Hi, yes I never normally video anything, and I'm just used to holding my phone vertically. I didn't realise this mistake until after I had finished. If ever make another one I will hold it horizontally.
Well done really good work
I gotta say, watching this is like watching a series on Netflix. Today I have started to repair my Sony KDL-70W850B and using your video as reference to what I need to do. I've got most of it apart and I'm on the "episode" of removing sticky tape off the corners right before trying to separate the back from the screen. Oh how this would be so much easier with someone helping me. One question I have for you is... why did you not add the LED strips with the back laying flat on a table instead of standing up on its side?
Limited space. I already had the screen on the table. I would have needed another table of the same size. Good luck!
Hi there. I have the same TV and I have just replaced one led because of 6x blinks. After assembling the TV I got a darker screen horizontly from the middle towards the right side. Do you any idea what the problem could be? Is it the copper screen attachments under the bezel? Any help will be appreciated. Thanks.
Sorry to hear that, I don't know what that could be.
I started this same repair and now I had 1 of those brown ribbon flaps on the sides (that you show at 30:05) come off. They are not connected to anything. Wonder what purpose they have and did I just trash the panel?
Yep. They interconnect parts of the panel. How did it come off? That panel is for the bin now.
@@michaelclift6849 I cannot tell at which point that ribbon flap came off. My best guess is when I was lifting the panel up. It was either my butterfingers/my dog. Took it to the recycling center.
Sell it for parts. Remove motherboard and sell.
hi i watched your video it was great by the way the only thing i buggered up is the deflective sheets you said to tape the corners so we dont mix them up well i forgot to tape them the grandkids bumped them and they ended up on the floor i put them back the way i thought they went and yeah the pictures not right plus i can finely see the leds through the picture would you have any idea which order they go in thanks j
From memory, there were some staggered tabs on the edge which indicated the order. I only remember that the courser one's went on first (closer to the leds) , and the more opaque-foggy one went on last.
@@michaelclift6849 thanks so much
I have same TV with same problem. Found your video just on time, Starting to repair the TV in couple of days. Where did you get the strips ? Aliexpress. thx alot for the video.
Hi, no Ebay. Good luck!
@@michaelclift6849 Thanks for the video. I also had no experience repairing TVs like you. Finally TV is working again. Even though I got full strip set, I only changed single strip(had only one faulty led). Hope I wont regret down the road and wont need to open it again.
Do you have a link where you bought your backlights
I checked my ebay history. This is the backlight kit I bought: www.ebay.com/itm/272580913844
And to stick them down, this is the special tape I bought:
www.ebay.com/itm/313403471775
Thanks for the video! I'm about to tackle this project! Do you remember how wide of tape you used?
If you mean the double sided tape for the LEDS, it was 15mm, which was a little wider than needed.
@@michaelclift6849 thank you!!! Is your tv still working?
Yep, it's still fine. I don't leave it on 24/7 any more though. When it failed it had been on non-stop for nearly 2 years.
@@michaelclift6849 it is finished!! All done went great! I was too afraid to put the chassis back on over the screen like you did. So I set the TV upside down, upright by the panel and tipped the cardboard under my panel up and slid the panel into place. More or less dangerous? No idea but it worked! Thanks again!!
@@alexwharton7407 can't argue with results! good work! Thanks for the follow up :-)
