Unfortunately, I don't any other ideas except to call 800-SAMSUNG to see if one of the representatives might be able to assist you in troubleshooting the unit further. If that's unsuccessful, they can assist you in setting up a service ticket so that the unit can be repaired.
I turn it on, it says load, and has been that way for days. I have tried to reset it, but the reset methods have not worked. IE turn off and unplug for five minutes, press the power button for ten seconds. Turn on pressing the l>> Well nothing works. For the first four seconds I can get the tray to open, I have tried an update disc I made, and even the update on usb. But nothing works. Any suggestions??
