820-3208-A Board no green light
I have a problem that I would like some help with on this 820-3208-A logic board I’m working on. The board looks really clean and there was no water damage,. However, there was some corrosion around U6990 chip and there is no green light on the magsafe. After cleaning the corrosion and replacing the U6990 chip I only get 2.74 V on pins 2 and 4. Pins 6 and 8 both have 15.50V going in. I checked for a short to ground on the pp3v42_g3h and did find a small drop to ground. I then felt around and noticed the SMC is really hot to touch. Please tell me that the SMC is not bad!!!!!
