Switch Lite Water Damage

Hey all,

Very new to electronics repair but hoping for some insight. Niece dropped her Switch Lite into some mop water and then tried to turn it on and charge it while still wet. Trying my best to fix if possible. Apparently only the left side fell in which looked to be accurate when I opened it up. Water spots mostly on the LH control board. I replaced that board as there were a few corroded/blown caps on it. Also replaced the battery as it would only charge to ~3.2vdc. New battery is charged up to ~4vdc but still no response when trying to power on. Any suggestions on what to test next or is anyone able to provide test points to trace power around the main board?


what backlight voltage do you see(yellow line) when you trying to power on with a charged battery?
