Black Rectangle on my 15 " Sharp EDTV

[JackVa1]

I have tried other forums and got no response so I have to ask here. It sounds crazy but here goes:

This happens only of FOXNews Nework
Always happens at night (small bedroom TV only)

I get a blacked out rectangle near the center of the screen. It covers maybe 35% of the screen.
It goes away when I hit the volume button , then returns in 10 seconds.

It goes away if I go to another Network, but returns 10 seconds after re-tuning to Fox.

Now the best part: I have Direct TV and a Cable feed to this set. It happens on Fox ONLY but on both TV inputs.

Please tell me you have seen this. I am stumped and I trouble-shoot Computer problems all day

Thanks

Terriffic!!

I knew I had no CC displayed on any stations, but my SHARP was not set to CC=off.

It was set to CC=T1

I had no idea, Very curios why only FoxNews was affected. Thanks a lot!!!
