toshiba 42hp66 HD plasma snowy picture
So far, I'm able to get around it by turning the TV unit on and off a couple times seems to solve the problem and eventually the picture comes in clear as a bell.
I'm not sure where the problem might be, but I've noticed that it has the same signal processing problem whether I'm trying to watch TV (the signal from the DirecTV HR20 DVR) or access my Mac's desktop (the signal from the Mac Mini).
Since I'm getting the problem while trying to "see" both TV and Mac, I don't think the problem is due to the Harman Kardon AVR 245 I use as a switch between the devices. Rather, I think it's something to do with the connection between the AVR 245 and the TV itself. I've tested the physical connection of the HDMI cable to both the back of the AVR 245 and the TV, and those both seem fine.
I'm really hoping it's not the actual HDMI cable that's going bad. Not only because I paid the installer the unholy sum of $85 for the cable, but because the cable has been installed inside the wall so there are not unsightly wires hanging from our wall-mounted HDTV.
