Resetting a Samsung TV

[spreadsheet]

I have a Samsung TV (LE40B650T2W)

which after behaving oddly for a couple of days
seems to be jammed onto channel 101

Is there some sort of reset I could do to sort it?

Have googled it but got poor results

Probably find there is a reset to factory option in the service menu, although you do so at your own risk.

Instructions for entering the service menu are something like this

Put TV in standby.
Quickly enter this sequence from the remote: [Info][Menu][Mute][Power]. If you do it too slow it won't work.
Use the power on/off button on the remote to exit the service menu.

Another option although a bit drastic would be to upgrade the firmware of the tv (if it's not on the latest) but i'm not sure how you do it on that model.

Yeah try those simple things first, I got too complicated too quickly xD
