Projection Screen

My projection screen TV has horizontal lines and flashes until hot. What is wrong with him?

She looks my tv taking longer and longer to warm up each day. The main screen of the television and all the supplies needed to heat for at least half an hour. The display flashes until the TV warms up. The TV is a projection TV that is about 10 years old. Does anyone know what would cause the flip of the screen and how much it would cost to fix?

About $ 400.00 to repair the problem .... Of course, I prefer to look at first, then quote a price .... and turn off the TV .... I see that it does not work when you get there.
