Saved me some cash there bud thanks, I just replaced the L.E.D strips in my 47" LG. My 13 year old son did most of it watching the video and pausing it as he went, thats how good this guide is, well done !

Just replaced LED strips on a 47" LG, this guide was brilliant. Many thanks, clear and concise.

This video is ace. My lg TV died over Christmas but the flashlight test proved that it was the backlight that was blown. I bought lights for £60 and followed this video exactly and it now works perfectly again. Thank you so much, you've saved me a small fortune!!

Thank you for posting this video. The step by step instructions helped me repair my father in laws LG TV with very little trouble, keeping it out of landfill! Amazing.

I used these instructions to replace not an entire strip but just a single diffuser on the strip. It had dislodged, and all it needed was a little bit of glue to put it back in. thank you very much; these instructions were excellent!

[ackyphiri]

Thanks a lot, you saved the day. Today I did purchase backlights and did a DIY on my LG42'' TV following exactly what you demonstrated and my TV is back to life. Cheers man

Very grateful for this video. TV went down christmas eve, 2 weeks out of warranty. Local repair service quoted £200, LG Quoted £300! Got replacement array for £35 and did it myself. Would have bought parts from you if not for delivery timescale. Excellent video, especially as I had never done anything like this. Thank you.

Thank you for the step by step video, it allowed me to replace the backlights on my lg42lb580v TV.
Using suction cups to remove the lcd screen was a great tip.

Thanks! I just replaced the LED strips on my parents' 32"LG TV following the steps in the video. It works now!

Just went over this video to replace LEDs on my 42 inch LG. Great video and instructions very clear. Save me 100 quid repair fee :).

Very nice guide. All steps presented perfectly. Following your guide, I just replaced LEDs in my brother's LG 42LB5500, and it works. Saved him some money for repair. Thanks for the video and please keep making these videos.

[StuMazza]

Excellent tutorial. Followed along and fitted new LED strips. All working again. Thanks 👍🏻

[wyattspence]

This guide was the bomb! I would have never been able to fix my TV without it! Thanks so much for making your videos!!!

Svaka ti čast, ne spade ti ni jedan difuzor, kod mene frkte kao kokice😀

[MariuszChw]

Thanks to You I just fixed my parents TV. Big Kudos!

[markweeks]

How do you know if it's the led strips that failed or if it's the driver I have an image of i hold a light up to the screen but no back light I'm going to order new led strips but not sure if it's the strips or the board that's failed ?

[osvhdez]

I just repaired my 42LB5500. Thanks for your invaluable guidance

What kind of tape are you using at 5.27? I think it’s a removable special tape! Thank you

[haajh]
