I've got an oldish (10-12yrs) NEC CRT TV that's decided to start playing silly buggers with me (or my wife to be precise).  Apparently, a couple of seconds after being turned on, the telly switches back off to standby.  She's tried doing it through the remote and manually on the telly itself.  Doing a complete power-off and on doesn't seem to help either.  No changes have been made to the home theatre setup.

As much as I like my daughter having an afternoon without Fox News, has anyone else encoutered something like this before?
