Flickering purple colors

[bkrieger]

I'm not sure if this is related to my TV or PC, but I have a 55" Panasonic VT30, connected to my PC Via HDMI. On my PC, I Have 2 GTX 680 cards, with everything connected to my ONKYO TX NR818 sound system via HDMI. When I first turn on my TV lately, I notice tge screen flickering in purple, and it leaves dots on the screen. After a few minutes, it goes away and the screen is fine.
Anyone have this happen to them?

Thanks

First find out where the colors are coming from. Connect the TV to another video source, and try a different monitor on the computer. Also by-pass the receiver to test things.
