Hi, I push the power button on the Sharp 27k-x2000 TV, the rely clicks, the picture tube energizes for 3 to 5 seconds, then it shuts off automatically. The only way to repeat the process is to unplug the tv from 120 volts and plug it back in. Then I can push the power button to repeat the same process. Before this problem occurred there was a horizontal line across the top that took 2 minutes to disappear. I am trying to diagnose which component is bad, have tested quite a few.
Anyone with help?
