Well, my problem is the power light comes on but no screen or sound. It is in the finished basement, but it is colder than normal because outside has been below freezing for a week now. Also had Dish network installed a few days before any problems. Initially, it would come on but the picture wouldn't fill the screen and was fuzzy. If you changed the channel, the picture would come in clear for half a second and then go back to the fuzzy, but now nothing. I disconnected the dish and hooked up to a antenna but still nothing.
After reading many of these posts, I'm guessing a power supply. But any info would be a blessing. Thanks
Yeppers that ia probibly what your problem is. This is a common thing for this model. Most of the time the problem is the power regulator and a capacitor. Without a schematic, multi-meter, an ESR capacitor checker, and the knowledge of how the cicuit works, you should not experiment with this TV. There are no user replaceable parts inside this TV set. Please seek out a pro to assist you with this repair. Good luck, and let us know what was wrong with your TV when and if you get it repaired.
