Hi.
I have an A1989 with only 5V.
Client says he felt a burnt smell on the day before, but I can't see nothing damaged on the board.
It passed all S-UEM2 tests, and I've found out later that It had PPBUS_G3H leak.
After removing the short on PPBUS_G3H, I still have only 5V on ampmeter, and U3900 (T2) is hot in IF cam, and so I'm assumig it is the culprit.
I'm assuming that it can't be replaced, but just want to be sure.
Does this diagnostic makes sense to you? Can I check something else to be sure?
