1. The full model number off the back of the TV is UE26C4000PWXXU.
2. I have had the TV for 2.5 years and have had other TVs in the house for longer without problems. The problem started a couple of weeks ago and was intermittent but now we can't seem to be able to watch the TV at all as it is flicking through channels and the volume is going up at a very past pace. I have to unplug the TV as it cannot be worked manually on the TV.
3. Once the TV goes on the manual controls for both channel, volume and turning it off do not work if it is in its crazy mode.
Hope to hear something positive from you.
