Guide/channel list button on Samsung TV remote works intermittently. Only way to access is through Menu button. Tried new batteries, software up to latest version, no luck. Other buttons on remote responding ok. Now Apps page just blank nothing displaying. Any ideas to what it may be?

Possibly a knackered remote. There's a quick way to check. Use a digital camera or mobile phone camera to view the IR LED at the business end of the remote as you press a button. IN the camera viewfinder, you sholuld be able to see the IR LED flickering - try it with a known good remote and you'll get the idea.

If it's knackered, prosbably a quick sojourn to EBay is in order.
