Short on PP1V1 and PP2V8 not turning on
Hello, I have a water damaged iPhone XS max, it was ultrasonically cleaned but a short was found on PP1V1 and PP1V8, I removed most of the capacitors on that line but the short is still there, could it be a possible CPU short problem ?
What should I try next?

Need more info. What are the readings you are getting on these lines? Is the short on the top half of the board or the bottom half?

Have you removed the two audio ic”s U4902 and U5002 yet? They would be the first things I would remove.
