Got a NEO, has a few problems, the main one being that when it boots up, you see this:

VIDEO RAM ERROR

ADDRESS WRITE READ
0000060F 55555 1555

What chips need to be replaced/what needs to be done?

Also, how do I replace the four lights above the cabinet? Any idea on how to pick the tubular locks?
 
The most common fix for the lighting is to replace them with a fluorescent tube. The units themselves are expensive, and hard to find, and a common fail point.

You can drill the locks out. On mine, I just took the back off and removed the coin door, then took the locks apart.

As for the RAM error, not too sure, but check a manual, or schematic if you can find one. There are a few guys on here that specialize in Neo Geo repairs, so you can check them out.
