      I think you should check feedback resistors.

          I do not know if you have the schematics? I believe these are them. Have you tried the HDMI port? Also. make sure the ram boards at seated correctly.

              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...

              MSI GTX 970 4G V316 1.1 Loads of lines across screen suspect memory??
              by cheeky2
              Recently purchased this MSI GTX 970 Gaming 4G graphics card and card shows plenty of lines when booting up to bios and into Windows.
              What are your thoughts memory issue as I don't have that much experience repairing graphics cards?
              I have checked before plugging in card for shorts on the 12V power rails, PEX etc otherwise I wouldn't have plugged the card into the motherboard.
              The screen shuts down if I load the drivers on the card.
              See attached pictures.
              Any thoughts with what is likely to be the issue? I suspect a faulty Samsung memory chip and if so would...
