Hi Bill,
Sure sounds like a shorted blue CRT to me. Couldn't you just unplug the HV,
and the CRT board from the blue CRT, and see if it'll power up on the red &
green?

power-up momentarily arcing in blue CRT and lighting screen with blue
retrace lines then shut down.

point I dialed into technical and set the phone down, forgot it, and went
back to it about an hour later. Same canned music and recording thanking me
for continuing to hold.
> This is a nearly new unit and I suspect the problem is a short in the blue
CRT. Anyone have anything on this unit with these symptoms?
