    50PX950-UA screen flickers

    Hi guys, long time listener, first time caller...I have a 50PX950-UA that was working but the main board went out according to the Toms Service Manual. Jumped the two pins and the test screen popped up and looked like it should. Fast forward a week and I get a main board from TVPartsToday which looked kinda bad...but not great. They said it worked and offered a full refund if it didn't so I popped it in and the tv turned on but the screen went to pink and the tv didn't respond to the remote or the touch bar and it has me kind of concerned something inside burned up. Fast forward to today and I receive another board from someone else and now the TV powers up but it flickers and you get all sorts of horizontal lines. If you have any idea what this is doing or where you'd start trying to figure out the issue let I'd appreciate it. Hopefully it's not scrap. Attached is a video of what it is doing. All voltages check out per Tom's Service Manual as well.

          Nailed it, there's a board after the main board that was disconnected to do the main board test...apparently that strip wasn't plugged back in properly. Disconnected and reconnected it and it's good as new

              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...

              Philips 46PFL8007K/12 - Picuture flickers on half of the screen
              by Capacitorial
              Hello guys.

              I recently got a TV that has the following problems:
              1. Sometimes it has to be turned on and off a few times, to boot up. Sometimes it starts from the first try
              2. When it is running normally, the right side of the screen flickers. Sometimes it is just a square of transparent white maybe a 1/3 of the right half (top right)
              3. The flicker is also sometimes a square that is filled with lines
              4. I noticed that when the TV brightness is set to max, it flickers less. I think the Standard setting is the worst where it comes more frequent
              5. When it runs a few minutes it gets better,
              ...
