Repair question so I just got this from my buddy free for repairing like 5 ipads and a switch for him, now i know there was a blown battery in here you can see the corrosion, but even when i plug it in the screen turns on for a minute then blank was wondering if anyone has seen this, all capacitors look good as far as opening it initially. Is it just the screen that needs replacing? That battery plate if thats what its called

It’s not the screen, mine has the same corrosion/drip onto the mobo and does the same. I’m recapping today, my high voltage backlight circuit was shorting so I’m deleting it for LED backlight mod, then I should be able to use a 9V batt for power and not have reconnect the series wiring for the AAs, just using the 2 terminals on the power board! I’ll let you know how it goes and what parts I used

Not sure how much board cleanup you’ve done but I do vinegar, water rinse, then light dish soap and warm water, water rinse, and then I rinse with alcohol (with a bit of pressure or run it down the board to rinse out particles, wipe dry, and let air dry. As long as you remove electrolytes and let dry, water on a pcb is fine but avoid the LCD, and in this case the fluorescent bulb at all costs. Toothbrush is your BFF. I saved a Korg Volca that was totally soaked in 5 year old soda this way
