Initial complaint was no picture/sound when using input#1(s-video for dvd). Tech replaced the board with the actual input &power supply jacks(G board ?). Now input#1 is fine(S-video,audio and video), but input #5(HDMI) causes the same problem. It will work for a few minutes when using input#5 then shut down. No issues whatsoever when using input#1. Green LED stays on when this occurs.First board was replaced under extended warrannty/They refused to replace it again, opting to buy out the remainder of the contract.. After some haggling, we agreed to a decent(higher) buyout figure. I would love to repair this seldom used TV, as I love the picture and would really like to pocket most of the buyout $. I would love to hear from anyone who has successfully repaired one of these common failures.
