  • I fixed a LG TV that has Black Screen that is Caused by the LCD Panel Itself. This TV has all good working parts except the LCD Panel itself. I fixed it or did a remedy by using the Tape Method.
    This kind of problems are a bit common to 4K LCD Panels.

    I have a 42 inch tv that has been standing outside for a couple of weeks coz it suddenly stopped showing the picture, so I was gonna throw it away. But then I saw your video and thought I might aswell give it a try.
    My tv is a lot more complicatet that the one you showed, but I could still use the same principals as you showed, so I was still able to narrow down where the problem was.... AND IT WORKED 😀 Thank you so much for this helpful information 😊

    This actually worked. Bad design on LG's part. It's obviously a common problem, and the TV should be able to identify the shorted pin and exclude it as a fail safe instead of just shutting down the whole signal. Most people won't try to fix this and will junk a perfectly good TV.
    Once I found the problem area I had to do a REALLY small piece of tape or else it blocked too much of the signal and I could see lines on the screen. Got it working and it looks great. Thank you!

    • @atanbajan
      @atanbajan  8 місяців тому +1

      Nope, you cannot just replace the cable because the problem is in the LCD panel itself. What we can do is just block the connection that is going to that defective portion of the LCD panel that is why we cover some pins.

    Managed to fix it. Covered 2 pins and all is good but there is another issue..... Half of the screen is slightly darker and u can see that screen is gently flashing. Thats normal effects? Or maybe i coverde wrong pins. Thanks for any help. Regards

    • @atanbajan
      @atanbajan  8 місяців тому

      That slightly dark and a little flashing could happen on some tvs and some model of tvs. Since different tvs have different designs so the pins that are shorted or has the problem has different functions and adjacent pins closest to it.
      That slight datk and flashing after effects are normal in some situations because we are blocking signals that are supposed to reach the LCD panel.
      There is 50 to 60 percent chance that everything will work perfect if we block connections going to the panel. Assuming that you covered only the pins that are needed to cover.

    • @atanbajan
      @atanbajan  11 місяців тому +1

      If you still have lots of pins covered by tape it could cause that black vertical strip. Narrow your tape to the minimum.
      Also it could be a bad COF IC that is causing that problem. It could also be that the vertical strip is the original problem which is a result from either a bad COF or LCD panel and since you covered the connection going to it with tape, now the TV shows picture and at the same time it shows the problem itself.

      @@jayredd5614 I cannot really tell what is the problem unless I tested your particular TV. But here are some guesses that could be the culprit; 1. Leaky LCD SCreen/ Buffer Boards 2. Main Board Problem / Solder problem in the BGA ICs. 3. Leaky LED in Backlight Strips 4. PSU Unit 5. Loose Ribbon Cables. So as we can see it is really hard to say what is the problem if the TV is not thoroughly tested.

      If the original problem was the backlight assuming that all other parts are good. And you replaced the backlight strips with new ones. And it did not work after replacing backlights, the problem could be the new installed backlight is defective due to a bad single LED or a broken voltage path.
