Ok, so my aero fighters won't boot, here's what happens...

Turn it on, get the first 5 seconds of the into music, then audio stops
Gfx display a just garbled screen with artefacts all over, frozen, no movement.

What I've done...

Tested Power Supply voltage from brand new switched PSU tested good
tested monitor, monitor working

checked PCB for...
checked traces for scoring and cracks, none found
Checked solder points and traces for heat damage, none found
brushed board with a brush to remove loosened particulates
blew off board with compressed air to remove more stubborn particles
brushed again to remove anything that might have been loosed with compressed air
used compressed air once more
checked caps for bulging, discoloration, and discharge, none found
removed all removable ICs, polished legs
brushed, blew off, brushed, blew off IC sockets
brushed and blew off IC chips and reseated into sockets
Polished jamma contacts
tested power going to board, power normal

any ideas?

PS: Test Mode doesn't even work
