Mind boggling screen issue

So here's the story, I replaced a screen with an aftermarket screen on IOS 10, screen worked fine, but the proximity sensor had come away from the camera flex so wasn't working, took it apart to try and reseat the proximity sensor, it still wouldn't work, whilst reconnecting had forgotten battery was still attached and blew the backlight filter, sent it away for repair, came back everything working but the home button, turns out the main home button flex on the screen had become faulty, in the mean time I had updated the IOS to 11.*.* and purchased a new screen, new screen wouldn't work, purchased several more screens and still won't work, I have bought 2 Genuine Apple screens and they won't work either, I have restored with DFU using non-gen and gen screens, now the strange thing is I still have the screen that was on when I blew the backlight filter and that works fine, and I have another screen with slight fault and that works fine, this morning I decided to try the gen Apple screen again and it fired up!! But only for about a minute, it was showing lines then the normal screen then it was fading then showing normal screen then it went off (black screen) and hasnt come back on again since? Any ideas please???

Okay, that's a lot of variables to sift through. I would stick to what was known working for now; that would be the original aftermarket screen.

The ris here is that with all of the connecting and disconnecting of the screen, you may have damaged the connectors, either on the screen or on the logic board...or probably both. Take a close look under magnification to see if the plastic part of the connector is mangled up or if any of the gold-plated contacts are bent or missing.

The other possibility is that the backlight circuit/filter may have blown again. When you connect a screen and it doesn't appear to light up, you need to shine a bright light on it to see if there is a dim image. That would tell you you have a backlight issue because the LCD is working.

Commentaar:

The original aftermarket screen has a fault with the main flex home button cable so unable to fit that, the backlight filter has not blown again and the connectors must be fine if 2 other screens will work when connected, I can't use either of the working screens as one has the main flex problem and the other is the wrong colour and has shadowing on the screen
