[smashed]

Ok,
I have done some more investigation. Took it to a friends house, and plugged in. It worked fine. Brought friends box back to mine, and that worked fine..great. Then tried mine at home, and bingo, it was working.

Anyway, thought that was strange. But the hard drive was whirring at full speed for 12 hours so I turned it off, and then lost signal again.
Took it back to my friends, and couldnt get a signal for toffee, even though my friends box works fine.
So the problem is definitely my box, but it doesnt explain why it works sometimes, but not others. Any advice please?

Also , when it didnt work around a year ago (for a few days) I tried it elsewhere, and it worked straight off. Took it home, and it was fine again.

It is almost as if moving it in transit affects it, yet that makes no sense as it works until you turn it off.
