I recently picked up a Macintosh LC with 12" monitor, and when I plugged it in, I got nothing. I then replaced the power supply with one I had recapped earlier, and the fan spun up, and it chimed. However, there was no video output, and when I looked inside to pull out the Maxell battery, I noticed that the area around some of the capacitors was covered in electrolyte. Upon pulling out the board, I noticed that a liquid had been spilled on the board at some point, as there was a brown goop around the back edge near the ports and on a few chips near the audio circuitry. The entire bottom of the board was also coated in a different type of residue. After cleaning the board with 91% IPA, it no longer chimes.
What should I do to get the board working again?
