Actually not my television. Was trying to set neighbour's Sky box to record. As I said, can't shift the Life's Good logo and there seems to be something recorded behind it, showing less than an inch above the LG screen.
Seem to have got it work, but not a straightforward reboot of the Sky box, like with mine. Or did you mean the TV itself? Anyway, after doing everything and checking the input on the TV remote it now seems to be working.
