Black screen of death, LED powering up, but no display.
I have opened this iPad and tried swapping out the LED for a new one from eBay, but the same issue occurs where the machine powers up, digitizer works with voiceover mode on, but there is no display whatsoever shown.
I tried all the usual methods of reset, reboot, hard reset, recovery mode, but there is something wrong with the LED output.
Im assuming this is a circuitry issue, but don't know how to discern that from looking at the internals.
Can anyone tell if this is an issue that some soldering would fix? In other words, do you guys see a visual issue with the board? I don't have anything unplugged in these pictures to expose the pins, would that be necessary to tell if there is an issue?
@flannelist here some pictures I took.
I see some "scuffs" where the arrow points and the components that have the 2 red dots, but am unsure what these are. Does anything stand out? If the resolution is crap, I will post some high res stuff assuming the forum allows.
I appreciate the attempt to identify my issue, but more importantly the info given to help me learn what I'm looking at and how to troubleshoot!!! Thank you
Apple wanted to replace it for $250 for same model, but since this one just crapped out, there was no way I was doing that.
Posting a couple more clearer pics. I have a multimeter and am going to look into how to test the diodes. I assume I'll start with the LED pins and see what I can report back with.
Presumably if this is a diode or board issue, this would still require advanced skills to actually fix, but ideally I could get a shop to fix it for cheap since I might identify the exact issue for them.
Is dit een goede vraag?
@oldturkey03 its hard to say from the photos, its possible that the filter is bad but without it being checked with a multimeter i can't say.
