    Hey man, just want to say thanks. I used this video and followed it step by step and repaired a 65 in LG tv I found in the dumpster! Lol this TV is great and costs thousands brand new! Only cost me $25 for the bulbs! Thanks a lot for this man! Greatly appreciated.

    I bought the back-light strips off of ebay, insalled them myself, and got the tv to work. This video helped me a lot. Thank you.

    I made an H-frame out of wood and attached 4 smaller suction cups to it. More secure and no risk of damage.

    Try picking one end and drop it slap 👋
    The back of the TV
    Let the TV 📺 heat up and repeat
    This worked for me
    The led may not be bad
    The connection is bad

    great video as always, how do you deal with individual replaced diode that are brighter than the rest diodes? thanks. A dimmer led is not that noticeable, but it seems a brighter one will be easily spotted when you have the screen back on. Thanks!

    • @bigdog8882
      @bigdog8882  2 года назад +1

      probably not, just make sure that the led cover is centered on the led and it should be fine.

    At the end all LED must be working? Or TV will work if some of them are dead? I found this 55 LG TV on dumpster and 37 out of the 55 are dead and lights are blinking just like your video

    Hi Big dog, I did everything exactly as you said, it worked, then I putted the LCD on top to test everything before to assemble and it worked just fine, felt like "work is done". But after assembling (and I tried to be so careful specially with the LCD), the image is messed up, there is a white strip going from side to side and the LG logo is repeated all over like a shadow, then little by little the whole screen is turning into black. What you think is it? Visually the LCD look great, I don't think it's it

    I have an LG 65" LED tv. Occasionally it reboots itself over and over again. Not screen flickering but a reboot as if you were turning it on and off. Some nights it reboots itself like 50 times in a row every few minutes, sometimes it doesn't happen at all for as long as a week or two. Any guidance on where to start testing or replacing? Thx

    superb video, sir. As far as the LED tester goes, can't I just apply a DC voltage at the test points on the strips and test that way? If so, do you know the voltage?

    • @MarcysPlayground2.1
      @MarcysPlayground2.1 4 года назад

      Yes I can use a multimeter.. on DC voltage ground it to the chassis and proceed to test it

      @@MarcysPlayground2.1 thank you - I had a dc power supply and was able to test the individual leds and the strips as a whole. Worked pretty well. Found at least one bad led. Can’t believe they’re in series like cheap Christmas tree lights.

    Also when testing just put the probes in series with the leds rather than removing the connectors, I use an adjustable power supply at a set limit. Also best to change any that look a blueish colour they normally start flicking at lower backlight levels.
