[SOLVED]820-3437 All rails present, fan spins, no display, doesn't boot, CPU not getting hot Hi there, I have a water damaged 820-3437. I replaced a bunch of corroded components, repaired some traces, and I'm getting a fan spin, but no chime, no display, no boot. I have all rails present...

Hi there, I have an old 820-2610 that charges, starts, chimes, boots etc. but cuts out after running for a few minutes. Sometimes after one minute, sometimes after ten minutes, but it won't run for much longer than that. It gets the all clear from ASD. I'm aware of the C7771 issue with this...

Hi there, I have an 820-2936 and I'm trying to diagnose an issue with the headphone socket. When I got this board, the computer wouldn't switch to the headphones when I plugged them in. After inspecting the board I noticed there were a few components that had been knocked off around the...

Hi there, I am a novice Mac repair hobbyist, so I apologize if I have missed something obvious. I was given a broken 2009 A1297. I had green light on the charger, but it wouldn't power on. I opened it up and found some very noticeable water corrosion on U7201, particularly around pins 25 - 30...

Hi there, I'm very new to this, so please go easy on me. I have a late 2008 A1286 that is in apparently perfect working order, with only one small exception and that is that the little battery indicator light in the side doesn't work. My first thought was that the little button/light assembly...
