I have eliminated all remote batteries, and disconnected the anynet device and I still have had this problem.
My UN55C8000 that I received 2 days ago does the same thing. Each morning watching satellite, within about 10 minutes of powering on (and remotes hidden away), TV changes input to PC, static appears in the back, lower right red indicator is flashing quickly (as if remote is sending commands) and TV is unresponsive to front panel buttons and most remote buttons. I am able to get the input back to HDMI by pressing Menu on the remote, but takes repeated tries. To bring the TV back to normal, I have had to physically disconnect power cable from the wall (very annoying) as the regular power button doesn't work.
Purchased from Amazon.
TV had firmware 1006 (02.20.2010 I think) and had the problem
Updated firmware yesterday to 1016 (04.09.2010 I think) and still had the problem again this morning
Yamaha RX-V765 AVR connected by HDMI to TV. Tried with HDMI control on and off, no difference.
PS3, Dish Network PIV 722, and PS2 connected on HDMI to AVR
Other than the single HDMI connection from AVR and power cable through basic surge protector, no other connections to TV.
Called Samsung and they say something is definitely wrong with my TV, that its not something previously reported to them. They offered to schedule service but I'd rather just exchange with Amazon. Frustrating because its not easily reproducible. The rep said if possible a video of the TV "doing its thing" might be useful for a service tech.
Also, on an unrelated note, TV has one dead red subpixel about 1 foot up from center (looks like a blue dot on people's faces, if I'm looking for it - doubt a typical owner would ever notice).
Other thoughts: Picture is excellent. Black isn't perfect but better than any LCD I've seen. Clouding is not an issue, and I don't have "flashlighting". I compared last years 8500 and this years C8000 in store before purchasing; 8000 had better PQ IMHO in store, and I'd take the lack of blooming on the C8000 over the potentially better blacks on the 8500. I do find the dongles annoying - personally would prefer a 2" thick TV with standard inputs and a removable power cord than a 1" thick TV with a bunch of dongles. Someone raised concern about the 1/8" 'analog' to optical digital audio: The connection to the dongle is digital, not analog. Hope this helps.
