I recently picked up a A3000 off ebay without reading the description to well and have run into a problem. I get a black screen when I start it.

So far I have tried:

removing everything
only the daughter board
remove ram chips
replace CIA from good 3000
swap power supply from good 3000
vga monitor
commodore 1084 monitor
ensure all chips are seated
double check jumpers

Now for what I think is the problem. The battery leaked some time in its life and has left a mark on the motherboard. Also, there is a green buildup on 2 of the chips beside where the battery was well as on some other components.

I am going to clean up the area a bit more, but am wondering if there is damage further below the area.

An ideas what I could check?

There's a fairly high chance that the battery corrosion has done some damage which requires some good attention.

If it helps, I recently wrote a page detailing some common A3000 booting problems here.
