Unit responds to remote and turns on power LED.

It was having problems losing HV to CRTs intermittently; hitting the chassis
would make HV go on and off, but left sound on.

Tapped on the multiplier then was OK for a while, suspecting bad solder
joint on near multiplier resoldered suspect solder joints.

Now no HV or sound. Inspected work for shrts etc. but all looks good.

Any experience with this type problem?

TIA
