Dale, Welcome. I love it when a customer tells me "It did the same thing before and they just replaced a board". I'm not familiar with this particular model, but shutdown could be for many reason, though I don't think those chips(possibly convergence chips) would apply in this case. You need to know why it is shutting down. If it is playing for a few minutes OK, then shits down, you will probably need the service manual to pinpoint the problem.

Ok anyway I don't work on Big Screen TV's but it is a friends he said that he has had the power supply board replaced before for this same problem It takes about 15 minutes for it to come on after pushing the on button and it will play for a while and then shut off. I am not familiar with Big Screens I work on monitors and smaller tv's. I was told by a friend that there is a board that has 2 STK's that need to be replaced can some one help me on this I don't have a sam's for it. If you could help me or suggest some place I can get a rebuilt board for it I would appreciate it Thanks Dale Brewer E-mail : dale.brewer@xxxxxxxxxxx ------------------------------------------ To REMOVE your email address, click here: http://www.tech-assist.org/unsubb.html To CHANGE your email address, click here: http://www.techassist.net/forms/change.html ------------------------------------------ ***NEW*** Tips Added Instantly!!!*** Submit Repair Tips here: http://www.tech-assist.org/secure/tip/ ------------------------------------------ To REMOVE your email address, click here: http://www.tech-assist.org/unsubb.html To CHANGE your email address, click here: http://www.techassist.net/forms/change.html ------------------------------------------ ***NEW*** Tips Added Instantly!!!*** Submit Repair Tips here: http://www.tech-assist.org/secure/tip/
