No, no buttons sticky
I thought that this might be a Remote Control problem, do I need a new remote control?
Or is it a software problem, does Samsung have a software update?
I really do not wish to start digging around in the back of the TV set.
I've tried again pushing and unpushing all of the buttons on the side of the TV set. This appears to have solved the problem of channel changing. The remote control now works OK. I'm not sure of the volume increasing automatically- we will have to wait and see. This happens very intermittently.
I hope that your advice on the side buttons works OK.
How do I contact you if the volume increases?
