I picked up a Color Classic this past weekend and it would not boot at all. However, the fans would power up if I removed the logic board and plugged it in. I started looking closer at the board, which appeared to be in pretty good shape (PRAM battery had been removed, didn't notice any damage from any leaking caps). I did use some alcohol to do some surface cleaning, but the board was pretty clean.
That's when I noticed one of the pins on the edge connector had been pulled back and was bent in half (I should have taken a picture). When trying to bend it back, the end of the pin broke off. I was able to solder the pin back in place (I'm not good at soldering, but it appeared to stay in place and keep in the channel that it was meant for. I'll throw some pictures when I have a chance to pull the board out (I'm trying to put as little stress on that pin as possible, so minimizing the number of times I'm pulling the board out).
Anyway, I was still unable to get the computer to do anything when the logic board was inserted. No lights, no chime, nothing except a faint sound of the CRT powering up when plugged in. However, I read somewhere about the ability to potentially revive a dead Color Classic by leaving it plugged in and turned on for an extended period of time. I felt like I had little left to lose, so I left it plugged in for a day. I actually forgot I had done it and when I remembered, I grabbed an ADB keyboard with power button, plugged it in, and hit the power button, expecting the same lack of activity.
However, this time, I actually got a power light on the front, a very quiet startup chime, followed by the boot crash chimes. While the boot crash chimes are on the second half I get the first of 3 generic beeps. I'm also not getting any picture on the screen. I'm guessing the 3 beeps may be an indication the RAM may be bad. And the board probably needs a re-cap, along with the Analog board / power supply.
So, What's the concensus on best next steps. Should I do a thorough load cleaning? If so, what soap do people use for the slack and scrub phase. Assuming I should remove the ROM chips? Given that I'm not sure what state the analog board is in, should I not bother with the logic board until I recap the Analog board?
Appreciate any advice you all can provide!
