Hello. Got an 820-00165 board here with no power. It had little corrosion around U8020, so I removed the IC, cleaned everything and replaced the IC. Still no power. I get a little low voltage on R8020. It should be 3.42V but I get only 2.9~3V. Replaced the IC a lot of times already and same result. If I inject 3.4V on R8020 pads the board starts, but obviously this isn't a solution. Already lifted all caps on the line but same result. Any ideas on where to look?
