sounds like you might have an auto overvoltage shutdown circuit kicking in. The hivoltage goes to high and the monitoring circuit auto shuts down. More than likely trouble is in hivoltage circuitry. If you have a transformer that will allow you to bring up the set slowly without shutting down and you can look to see what's happening.
