Amiga 500 problem

[Henkie]

Hello,

I have the following problem when i put the power on on my Amiga 500 i get a white screen on the tv. I put muyworkbench disk in. The disklight turns green hums 2 times and stops.So the amiga isn't booted. But the strange thing this morning when i wanted to connect him to a other tv he loaded very long. But i saw no picture because the tv didn't use rgb. So i brought him to my gf's home and tried it there and there was a white pic but he doesn't load. Can it be because i moved him sideways i a bag.  What can be wrong. Can it be that my disk is corrupted because i placed the Amiga on my tv?

I have put other disks into the drive (games) but the only thing you see is a white screen. And they hun twice to and then stop.

I have never seen the kickstart screen only a total white screen. He loads now for a long time but when he stops the screen is still white.
