I've had my Samsung LN46A550 for about a month now and a few times I've either turned the unit on or changed a channel and got no picture/image (picture went black without any indicators for "Searching for Signal") but there was audio coming from the TV. I turned the unit off and then back on, and the picture came back. This has only happened a handful of times, but I was wondering if anyone else has experienced this, and if there's a fix. I may consider checking out the firmware version, and upgrading it if it needs this.
Thanks,
Mark
