HDMI White noise

[xavgo2]

I have a problem with my Sharp Aquos TV. My HDTV receiver is set to Auto HDMI mode so it's switching resolution to display the native resolution off the channel. When I switch between HD and SD channels, it happens that a get white noise. Just like the switch is not happening right. To get the signal back, I need to turn the TV off. How can I solve this annoying problem.

A firmware update from Sharp? I would return it to be fixed or replaced with a different model, one that works.
