820-00281 5v

Hey guys, liquid damaged 820-00281 came in with 5V on the USB ports. I measure 3.4v on PP3V3_G3H. One thing, if I plug in the USB tester on one side it stays on at 5V, on the other side it keeps turning on and off. No CD's are getting hot, checked with thermal cam and alcohol. CB301 has some corrosion on it but not shorted. Liquid spil images for reference:



Most liquid around U4200, not sure what this does and if it is related to charge?
