Hi All,
So my friend was visiting and he wanted to use my solder bench to solder on some WLED circuit board. My laptop was open on the side for RAM upgrade. I know my mistake.
So while soldering he had too much solder on the soldering iron tip and he just shook off the soldering iron on the table itself to remove extra solder on the soldering tip and it landed on the motherboard of laptop. He then out of fear tried to remove it using solder wick and did more damage by removing some components as well. So here I am with weird situation.

Good day all,
I got a 2007 MacBook from a friend. The fan was not working so it was overheating.
Once the fan was swapped, I installed an OS and it worked fine.
The board had quite a few corroded spots so I removed it, touched those spots with a soldering iron, washed the board in PCB cleaning fluid (I've done that many times), rinsed it with distilled water, dried it etc.
Unfortunately it doesn't work anymore. It does turn on, fan spins, power LED turns on. But no picture.
If I see that right, I have missed VCORE on L7100 (page 59)....
