Set came in dead 6 months ago?replacing STRS6301 fixed. Came back in yesterday with new problems: I can hear the HV come up as the set comes on, but it turns off after 2 seconds. I replaced the 135 volt regulator because I thought it was bad, but no difference. I put a variac on it and got the set to come on and stay on at 100 volts AC. I turned up the voltage to 120 volts and the set stayed on for 30 seconds. Q603/4/5/7/8 in the x-ray protection circuit all tested good. Does it sound like my STRS has gone bad again? Thanks.
