    RCA L42WD22YX5 waves on top side of the screen

    Hi,
    These waves, as you can see in the picture, come on for a few minutes after turning the TV on, then disappear. It's somehow temperature related
    'cause if the TV is turned on after being off for a long time, the waves take longer to disappear than if the TV was turned on after being off for a few minutes.
    I feel this could be related to electrolytic capacitors starting to go bad, but on what section? or does anybody have a better idea of what could be the problem?

      Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
      by Ryan.man
      Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

      My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

      This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

      Macbook Air M2 A2681 Kernel panics after screen replacement
      by reformatt
      Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

      It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

      iphone XS turns off when press on screen.
      by smic717394
      Hi,

      I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

      Samsung UN60JU6500, stripe on left side of screen
      by valvashon
      Friend sent me this picture of what their 60" Samsung from 2015 is doing. I didn't have any luck getting rid of a vertical stripe in another TV that developed one so I'm not too excited about trying to fix this one. It's mine for the asking; wish it had a dead power supply or bad backlights instead.

      Is this most likely to be a connection at the circuit board or where the ribbon cable hits the screen itself?

      Update: was just informed that this stripe comes and goes and has been doing this for a couple of months.

      Thanks, Val
