I have the above TV which has served me well over the years. The other day I noticed the remote wasnt working. Changed the batteries and still nothing. went to the flip out side panel on the TV itself and tried to change the volume and there was no response. In fact other than the on off switch none of the buttons work. Pulling the plug, leaving for a few seconds, then switching back on solves the problem and full control over the TV is re-established. Anyone any ideas what might be causing this, and if theres a fix I can do myself. Other than that a trip to a service engineer may be in the offing.
