The kids informed me today the our Barco 808 stopped working. The unit powers up and I've got green lights across all three CRT's and the power supply board. There is no internally generated pattern but the backs of the CRTs are glowing at the yokes. I checked the two fuses on power supply as well as the 17V pot and it all checks out. The back of the control panel has red lights on Standby, Main Power and Block Match and a flashing light on Processor Cycles. Any suggestions?

Check the red light(s) on the EHT board. Chances are one or both are on. If so, you are in HV failure mode, and you'll going to need to send me the EHT board, HV splitter and quadrupler to check out.

I checked and the light on the EHT board is on....I started following your recommendation removing the boards and realized I had done this about five years ago. At the time you tested the boards and ended up sending me back a new EHT board. What am I looking at price wise to just replace all three? Back then you were corresponding to me at matt@denisonhomes.net, that email is no longer active.
Thanks
