    Had the PVR about four weeks the picture started breaking up, I noticed when I checked the signal the strength was 80% but the quality was up and down 100% down to 40% then 100% and then 60% etc etc, changed the old looking aerial seemed ok for about ten mins, changed the downlead again seemed Ok for about 10mins, then the same bad picture on and off, I by mistake switched on the aerial 5votls output and the quality remains constant 100% and the strenght has jumped from 80 to 100% and ideas, the aerial is a bog standard 12 element from CPC no amp etc

    Assuming there is not a masthead amplifier then theoretically turning on aerial power should make no difference however you are not the first person to make the same observation. If it fixes the problem and you don’t get messages about the aerial power being short circuited then leave it on.

    HI martin thanks for the reply I get no message and I have no amp at all, I have been away for four days last night when I got back the power had tailed off to 80% and the quality was 100% but after a very short time my picture was jumpy etc, and the quality was all over the place after half hour every thing went to 100% and it worked all night “watching terry” is their a chance it could be damp in the wall socket or some kind of static build up and the 5v output is either drying something out etc, or is it a bad pvr/tuner

    Water in the aerial cable is certainly a real possibility. It needs investigating ASAP because if there is water and finds its way into the tuner the box will need an expensive repair.
