I have an older 27" Mitsu TV that is having a curious prob. After a few minutes it turns itself off. Turn it back on and it turns off, this goes on for 10 minutes and then seems to get tired of the game and stays on. As I said, "curious". It gets stranger... A red light flashes when it turns it self off near the bottom left. Does not light up when I power it off nornmally. And one other thing, if I set the sleep timer to say 30 mins, when it trys to turn off, it clicks but stays on. ANY help would be greatly appreciated. I am thinking maybe a leaking cap???
