RE: Cine Monitor problem

Next test: I’ll plug that monitor into my space wars, so we can understand
if it’s a power supply monitor. If not i’ll change both DACs. I was waiting
to do that because they are not socketed

Is it jittering or is it a stable screwed up image? If it's jittering, look
for ripple on one of the power supply lines.

Hi All,

some days ago my star hawk bagan to have the problem shown in the picture. I
swapped PCB with a speed freak but the problem was still there, so it is a
monitor problem.

I already changed all on board regulators (78/7915,78/7918) and all four TO3
transistors but nothing changed. lf133331 had been substituted with another
one too.

Do you have any idea?

regards,

Marco
