Have a Samsung 40" lcd about three years old. Worked fine when just connected to home theater computer via hdmi. Got a cable box with hdmi and plugged it in, now no hdmi inputs work. The computer won't even work when it's the only thing connected to the tv, and neither will cable when its the only thing connected. At first when things did work, it would take the cable box signal and when I switched to other hdmi inputs it was showing that image on all of them.


I updated the firmware in the tv, unplugged everything, rebooted...every conceivable combination. It appears as though it's the tv and it's a hardware problem. Could the cable box have damaged something since it did this immediately after connecting it?????
