Hi, I have a Toshiba 36ZP18P connected to a Pace cable STB (NTL). I am absolutely certain that up until yesterday, the TV (if turned off while the STB signal was selected) would automatically select the STB when the set was turned on again. Yesterday my son pointed out that it was no longer doing that, and after investigating I have found that he is right - it always turns on tuned to an aerial signal. I cannot find a setting that may have been accidentally changed and that will fix it. Is my set likely to be faulty, or have we gone mad and imagined it? Does anyone have a similar setup that they could check it out on please?
