Looked like I had FIXED set (replaced T-Chip), played great for almost 40 mins, heated T-chip to point where it was so hot I could not touch (before it would not take long to go out if heated).... THEN....Guess what?? Correct....Black blanking bar appeared! Customer wanted set back today for a game and did not wish to put more than $150 ($200 max). He decided to take set home and not bother with repairs. Was a Tough dog! Thanks ALL!
