Why has my set top box gone all fuzzy?

Question

I bought it about three months ago and it was fine, but all of a sudden it's started to go all fuzzy. I've lost about 60% of the channels to fuzz and lots of the others come and go. I've tried re-tuning it but no difference. help it's driving me mad.

Answer 1

I believe its often caused by heat.  Have you tried turning it all off at the wall counting ten and switching it back on again.  This may help.

Answer 2

It looks like you're experiencing something called the digital cliff edge, whereby the box has an incomplete signal and is trying to extrapolate.

Causes: Aerial has moved.Has your Aerial been blown around in high winds? Ground or nearby reflection of signals. Has anything been dug up, knocked down or built recently (this includes big trees growing in a line of sight). Attenuation: check your downlead coax from your aerial: is it connected properly?

Answer 3

you could have disturbed the aerial cable when you cleared out the loft. check any cable joints in the loft for loose wires
