Hi, I recently picked up this tv for a good price, however I'm having problems getting it to tune in to any channels for some reason. I've tried it connected to a roof-top aerial, tried auto-tuning it and got nothing. I've also tried it with a One4All aerial and pick up a very weak BBC 1 signal. There's nothing wrong with the aerial as it's providing my old CRT TV with a perfect signal... Everything else functions perfectly. Something else to mention, after the TV has tried auto-tuning it comes up with the channel names (BBC 1, BBC 2, ITV, etc.) but still no signal. Any thoughts or suggestions?
