Answer:

I knocked off a filter when i was removing the antenna wire.

But as you can see... it is somewhat of a design flaw.

They put the antenna clip very close to the image filter.
They glued the antenna clip in place so it cant knock off a filter on its own.
Getting the antenna off with the glue makes it easy to knock off a filter

Perhaps i would use some rubbing alcohol and some heat next time i try to remove this antenna

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?

Thank you!!!

@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.

So I was practicing with an old iPad I have and removing the power port flex cable from the main connector. I guess I was too impatient and part of the flex cable connector tore off and remains on the main connector. Botched it pretty badly. I don’t know how to remove it and am nervous to rip the pads underneath. There’s also some residue that is stuck on top of the main connector as well. Not sure whether to use more heat or what. Or if it’s just destroyed. I tried heating it a little and used flux and when I tried to clean it with IPA the cotton just got caught so there are strands everywhere. It a mess. Any suggestions? Thank you.

Anyways - I have tried to repair only my 2nd iPad ever from a family member the other day with just the worst luck. Everything has gone wrong with this repair and I'm so stressed at this point, I can't afford to dump any money into this as I believe I messed this up on my own.

Firstly, I was only asked to replace the screen as it was cracked. Ok, easy enough. Worked on it the other day and finally after 4 hours, got it all back together and done. Went to put the screen on and didn't realize the frame was gashed and CRACKED THE NEW SCREEN.

Anywhom, I said whatever and bought a new one and went to go replace it.

ISSUE THAT I NEED HELP WITH BELOW

• Did a function test with the old cracked screen and the newly cracked screen. All was working as should.
• After installing the new screen(2nd new one) it is now found that the LCD screen is glitching.
• It is that "Ghost Touch" and moves the screen around, types in random passwords ETC.
• I thought maybe it was the LCD itself. Replaced that, did not fix issue.
• I tried with old glass digitizer, this ghost touch glitching problem is still there. I know it's not the digitizer.
• Even if my hands are off the LCD screen and it is ONLY the LCD screen plugged in, I'm getting this ghost touch issue.
• Checked the board connectors and all pins seemed fine. From a visual inspection of the Micro PCB connections, all looked to have no issue. Do not have a microscope, as I'm NOT A PROFESSIONAL. This was only confirmed from a visual inspection.

I really appreciate the help and support, as I've been stressed and really losing it over this thing. Not really sure where else to go.

i'm considering

1st option: replace the current mobo with an ipad 8 motherboard

will everything work since it's almost the same(the only difference is the mobo)
2st option: replace the current mobo with an ipad 9 motherboard, current cam to 9th gen's cam

will it work?

current known: 7th lcd interchangable with 8 and 9

digitizer work on 8 but not 9 (will truetone work if I change the digitizer)

battery is the same on 3

Reboots are not spaced evenly at 180s apart, which probably indicates the sensor is responsive at times and not at others? At the beginning of the issue, I could sometimes use it for 5-10 minutes without rebooting, and sometimes less. Charge level fluctuates around 10-20% on each reboot and just randomly when unlocked. The reboots got more frequent and regular over time. Last night it seemed the iPad was charging very slow.

I took it for repair today,

They replaced the battery and the issue persists.

I've read TG0B is an NTC thermistor in the battery.... what could be the next steps? Any possible issues in the measurement circuitry?

I know it needs fixing but Santa is bringing her a new one for Xmas so I'm wondering if there are any tricks to get it to stay charging for the next 9 days without having to get it fixed?

now the LED screen appears to have some ghosting/shadows behind the image. never had this issue before.

Is this fixable? or do i need to replace the LED.
