My TV stopped working a few weeks ago. At first, the red light would blink, then a I would get a picture, but only a minute. Then some days, it would blinkl the red light, then I would have a picture (for a day or two). Now, it just blinks red lihgt and thre is no picture. I have treied to source a manual so I can find out what this means. It is repairable ? The Model is a P50XT70A. Any help would be most welcome, thanks, Melita Montague.

It sounds like a power supply problem where it got clogged with dust. Sometimes there is a reset on it, but before you run it you better clean it out. If you had done that earlier we would not be trying to solve this problem.
