water-damaged iPad 7

08-20-2025, 03:59 AM

iPad 7 won't turn on.
When I connected the DC power supply and turned on the switch, the current rose to around 70 mA, then dropped to 0 mA, and then rose again to around 70 mA, repeating this cycle.
The voltage was normal, including the secondary voltage.
Could the cause be the CPU?

Apple iPad Pro 3rd Generation 12.9" (A1876) No Power/Charge When Screen Is Connected

by grimacelord

Hello.

Working on an Apple iPad Pro 3rd Generation 12.9" that has a weird issue. When the display is NOT connected, the iPad will charge and power on normally. I know it's on because I can hear notification sounds and the charging notification sound.

If I connect a brand new display to the logic board, the iPad will not turn on at all. When I connect the iPad to an 18W wall charger and a USB-C ammeter, I can see that the iPad is attempting to charge, but constantly "resets" after just a moment or two.

For example, when I connect the iPad to...

iPad Air A1475 Boot loops after replacing battery

by trepachka

This iPad was working fine except the battery was not holding charge for more than 40 minutes. I replaced it with a new battery. I haven't glued the battery yet, just inserted it into the slot and held it with battery screw.

The iPad was powered on with the new battery and I am getting white screen with Apple logo for about 10 seconds, then the screen turns dark. It then cycles like this forever.

I know the battery is working because the iPad continues to boot loop without the charger until it depletes to 0% and the message displays I need to plug in the charger.

iPad Pro 12.9 (6th Gen) screen shuts off after unplugging device

by SarcasticOP

Greetings,

I have an iPad Pro 12.9" 6th gen tablet that had a screen replaced about 10 months ago at a repair shop and last week the screen went blank during use. The device was still on, notifications played sound for example. I have replaced the screen twice, both screens are working until I unplug it, at which point I can see that screen is on but is all black. If I press the power button, the backlight goes off, and when I press it again, the image appears for half a second and then the screen goes back to being black but on. This issue is not present at all when the iPad...

ipad Pro A1876 not charging - FIXED

by mon2

Hi. Thought to share a recent repair on the iPAD PRO A1876 that was flaky / not charging.

Issue was a defective dockflex charge cable.

See attached pix on the original connector condition.

Sourced a fresh cable from here:

https://www.esourceparts.ca/replacem...ad-pro-11.html

After the replacement - the display was dark and we almost were in a panic. The charge current was around 40mA @ 5V which is too low for this unit. Confirmed...
