I tested monitor with jamma board and it works smoothly!! WHEW!!!!

I tested with tugboat..

after playing for like minute or two. it starts flickering (shake) and i see several white dots appearing the GUI (graphic unit interface)

is it board issue? where do i need to look at???

need cap the pcb?

thanks
 
Check the usual suspects:
power supply voltages (at chips)
connectors, edge, power, video, etc.
fuses and holders.
clean edge connectors with pink eraser.
