Hi

When its shuts down does the LED blink?
Do you get a picture before it shuts down?

Hi

I think I understand what you were trying to say, Try disconnecting the HT supply to the line stage and fit a 'dummy' load(100w light bulb) and see if Ht stays up
If it does then likely to be either a S/C on seconadry of line output stage or line output transformer itself
