My Barco 1209 shuts down the CRTs after about 3 hours. Restarting the unit brings the CRTs back for a short period. Any ideas?

I'll bet the EHT shutdown light comes on when hte tubes go out. that means your HV is shutting down due to some HV failure, either the quadrupler (most likely), the HV splitter or the EHT board itself.

Thanks for your reply. What is the best way to attack this problem? Is there a board replacement that will cover the items you mentioned? Any help will be greatly appreciated.
