my nearly two year old humax foxsat hd box recently stopped working showing lnb short and then no signal, a tv engineer replace the old lnb even though it was working there is an excellent signal to the back of the box but the box does not recognise it , have tried a factory reset , the tv engineer took the box away to try on another tv nothing I have spoken roughly to it waved it about a bit and threatened it any help please , thanks
Thank you I will give it a go , just a little more advise if you will, the box gets as far as asking to detect a signal but can not detect the signal even though it is there, there is no obvious damage to the capacitors is this still likely to be the cause thanks for the help.
