Board had liquid damage to area between LVDS and U7090, then down about 2 inches, stopping right above Q7130. Board has green light, but no fan. Rails seem present, but ppbus is bouncing from ~8.4v to 8.6v pretty rapidly. Same increments over and over (i.e., reads at 8.56, then down to 8.42, to 8.50, to 8.59v, back down to 8.42v, etc). I can't recall what usually causes this type of cycling, but feel like it may be related to a mosfet not functioning properly.
Any advice would be appreciated--thanks!
