When I turn the tv on, after few minutes, picture disappears but sound stays on. what is causing it?

Question

I have Poloroid LFM-1911 for a year. It gave a great performance through out the year. Last week, whenever I turned the tv on, after few minutes, the picture disappears but sound keeps coming. I have to turn it off and then on again. It turns on fine but picture disappears. I don't know what is causing it. Please help.

i don't know if your type of tv has a color wheel, but that's what was happening with my friends tv and the color wheel was the problem and needed to be replaced.
