    Phillips 50PFP5332D/37 Screen Issues

    I have researched for what seems forever, apparently not in the right places, for the root cause of the issue shown below. Most screen issues I have found have been half screen top or bottom goes black, not what I am showing.

    The display is new, yes old tech but was sold and had a screen issue on set up. From what I have found the boards have different names depending on the manufacturer.

    Just looking for thoughts on what would cause the issue shown. It wont be getting put back together, just trying to save what I can from it.

    Thanks in advance.

      First step would be to unplug the main board and put the control board in test mode.

      I have no idea how you accomplish that with this model but if you post close up pics of the control board someone here might remember.

      ... the control board appears to be the smallish board middle-right.

          Thank you for the reply. Everything is already apart. I thought maybe it might be as simple when the screen does X, (fill in the blank) board is responsible. I just havent been able to find an example of what mine is doing.

              TV is old...
              check all electrolytic capacitors for capacitance and ESR, all connectors (pull out and reinsert all cables from connectors several times) ...

                      M1 A2338 screen and touchbar issues after cleaning up liquid damage
                      by jkruns
                      Hello everyone,

                      This is my first post after browsing this wonderful treasure trove of knowledge for many, many evenings. I've decided to learn how to fix these things, properly.

                      My patient is an A2338 Macbook Pro M1 (late 2020).

                      It had some corrosion around JT710 and JT700 caused by liquid spill, as well as against the protective barrier around the USB-C chips UF000 and UF100. So I took the main board out and cleaned it with a toothbrush and alcohol, then with alcohol in an ultrasonic cleaner. Cleaned the touchbar flex connectors as well. The board looks...

                      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...

                      A1502 screen only issues
                      by aazjo
                      I have a MBP A1502 (early 2015, 820-4924) with a screen that will not turn on. I have swapped screens with a cracked test screen and the computer boots and the cracked screen works for both backlight and image. The black/blank screen appears to do nothing.

                      I have collected resistant data from the cracked screen connector pins and submitted to OBData server:

                      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...
