Have a 2010 2850, that one fan spins, and the other "twitches"/pulses. Presents with very small amount of corrosion at J9000 but nowhere else. Customer reports that when trying to play graphic heavy games, it tends to crash. I suspect the capacitor for that issue, but cant be quite sure just yet. Ideas?

No Title

I have changed out the cap, and I get scrambled screen. The CPU gets really hot too. No other corrosion/liquid damage other than the two pins of LCD connector. I touched those up too. Get scrambled screen. Ideas?

That is either bad GPU/VRAM or board trace issue. I don't fix 2850 with these symptoms as they always seem to return and be miserable.
