MAC MINI and PLASMA TV's

So here's the latest:

I've had a mac mini (Intel) hooked up to my plasma (720P) in my bedroom for over a year I had the HD replaced with a 500GB unit but there have been no issues in quite a while.

So I took my mini away with me an connected it to my Pioneer Elete 50' HD plasma, everything worked fine but when i returned the unit today to my 42" 720 Plasam the following happens:

1) I turn the mini on and everything is fine the "Log In" screen appears and asks for my password.
2) The screen saver that I chose is there.
3) I enter the password and that's where the problem starts.
4) The plasma flickers and then goes dark.
5) The dark screen only happens when its not getting a signal so the mini isn't sending a signal.
6) I have 2 monitors at home and they work fine its just the plasma that doesn't, after log in when the plasma geos dark I can switch the monitor and it works.

Does anyone have any ideas?

Thanks

I would start with reseting the P ram, that will reset the video settings.... boot holding the p, r, option, and Apple keys and hold until you here it bong like 4 times
