The horizontal scan on my Magnavox 32-inch TV is going out. When first turned on, the horizontal scan doesn't go all the way from left to right and the TV turns itself off. I can turn it back after several attempts and eventually the picture goes normal and stays fine. Turn it off for a while and the problem comes back.

No question a component will evetually fail hard.

Any suggestions and what component and where to find a replacement?

Thanks.
