Model: Vasara
Symptom: Won't boot. Locks up.

Board wouldn't boot unless the board connectors were pressed together with bare fingers. When it did boot, the graphics and sound were corrupt. Resoldered the 2 custom video processors and the CPU on the main board. Resoldered the 16-bit surface mount ROMs on the program board. Replaced missing heatsink on the main graphics processor chip and tested.
