Power up and shuts off on it's own

Power up and shuts off on it's own

I power my tv on (Sanyo DP50747 Plasma) and the picture acts like it wants to come on, then shuts off within 10 seconds. I power it up again and the screen shows a little more. When I do it a third time it acts like it is warmed up and works fine after that. I took the back off and looked at the fuses however they have a white film over them. How do I fix this? It has to be something simple.
