I went to the color classic FAQ and found this:
and I also found this:
My CC logic board had a battery left in it, and when I opened it up, the battery had leaked all over the logic board. Using contact cleaner, I was able to get a lot of the goop off, but a small component, which looks like a capacitor broke off, and two chips, marked U3 and U4 still have slime on them. The component that looks like a cap I believe came from Y1. The can says "FIJAPAN" on it.
Because U3 and U4 are in such bad shape, I may not be able to rebuild the board. I wish U3 and U4 were in a socket, but they are not.
Can someone me what Y1 is?
I will try to figure out how to post photos to this forum so you can see what I am taking about.
