Defective Monitor?

Good afternoon. I thank you again for your help in the past. This time:I need help with a monitor that has gone blink-dark. This is a KDS model VS19. In the beginning it was doing very well. (This is used) Then it blanked out, so I took it back. After being told there was nothing wrong I put it back in the system. All was well for a spell, but then it went south again. Reinstalled my origional monitor, and it does fine. I discovered that I could cycle the thing about 5 sec. after blackout and it would come back, however now it is dead in the water. I hear the usuall start up for the tube-Bllliiing- but I can hear a circuit breaker or some kind of planed obsolescence device opening up the circuit as it goes blank. The B+ is still there, as I do not lose the "on" light. I am looking for some information on what the current draw should be. Also, where can I find a schematic to let me know if there is indeed a circuit breaker in this thing. The sound I hear does sound like a relay opening up. There is no reset on the back. Please advise what other info you need. Thank You. Harold Schmidt.

Welcome back Harold! :D

Sounds to me like the power supply in the monitor is failing (or failed). This is NOT something you want to attempt fixing yourself (very high voltages). I hope it's still covered by warranty. <_<
