I have an analogue STB and I recently had a fault with my cable modem. Since being fixed (splitter was faulty outside) I've had diagonal lines on my TV on channels BBC1+2 Wales, ITV and Channel4, when viewed via the TV tuning not on the cable channel. It doesn't notice much on my Widescreen TV, I think because of the 100Hz refresh rate its got but on portables its unmissable.

The cable modem had a 3.5db attenuator before the engineer came but he took it off but I'm not sure what effect this had on the TV picture because I took it off myself when the modem wasn't synchronising and it didn't seem to affect the TV picture. Would the attentuator only affect the TV signal if the modem was in sync ?

When I rang faults about it the guy said they only guarantee picture quality on the cable channel and not the channels which are received via the carrier signal. I wondered if this was correct, he also said if I asked for someone to come out they would charge me ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Â£25 callout charge if they found the cable channel was working fine.

Thing is how am I suppose to watch one channel and record another by just using the cable channel ? The reason I went on cable in the first place was because I could only get 3 english speaking channels.

Thanks.
