820-3662 Liquid damage no S4

Not what you want to hear but corrosion around U7330 will usually kill the CPU.

I was hoping since I had it working initially after repairing the damage that the CPU might be ok. Is the only way to check for bad CPU removing U7330 U7320 and U7310 and see if it turns on or do I just assume the CPU is shot?

You didn't mention it worked. The short on PPVBAT_G3H_CONN must be inside the board too. Is there a short on CPU Vcore?

I wouldn't put too much effort into this thing as the CPU may very well be dead. Corrosion around any Vcore regulators are usually deadly. If this is really the only corrosion on the board expect the CPU to be gone.
