Not so fast....Watching the set last night I would loose horizontal lock and was having to tweak the horizontal pretty far to get lock, nearly full clockwise. Then it would pop out of sync and I'd have to go to where it was originally set. I did this at least 4 times. Then after 4 hours I couldn't the horizontal to lock at all and the width shrunk too.

I tested the 6cg7 tube and found it had a short and wouldn't test on either section. I popped a brand new one in there that tested great. Same issue, no lock and poor width, assuming low high voltage. I pulled that 6CG7 out and it showed a short now! Thats not a cheap tube to be wasting away troubleshooting. So now I'm out of 6CG7's until my ebay order of 4 of them ships monday.

I'll do some testing in that section, there really isn't too much going on in that board. Any ideas on what would cause the tube to short out internally?

I thought this set was ready for the living room! I should have done the burn in testing in the garage.
