anyone have any ideas, i hate to get rid of this set right now but my problem is, when i first cut it on after a min or 2 it will make a pop and cut off . I may have to cut it back on 1 or as many as 6 times by pushing the main power button on and off to get it back on , then it will stay on the rest of the time . It seams to be getting worse, is it worth fixing and if so what is the problem?
