Have not had that issue, Milenkod, but occasionally I've experienced another odd behavior. Every once in a while when the tv powers up the colors would be all messed up, where it casts a sort of purple haze over everything. I disconnected the HDMI cable going through my receiver and tried a direct connection between my cable box and the tv. That made it better (less frequent) but didn't eliminate the problem entirely. I still had to reach behind the tv and disconnect, then reconnect, the cable into the HDMI port to get a normal picture.
However the other day I tried a different HDMI port (No. 4) and that seems to have solved the issue, at least for now. Has anyone else experienced anything like this? I have the 40" model, and this is the only problem I've had since buying it new.
