any help would be appreciated please..... picture is still there, have checked all connections, i've lost instructions, tv is about 2 yrears old and not under any guarantee. any ideas please? thanks in advance
If your TV has a headphone or other "audio out" socket test those to see if they work. If they do, it's likely to be a problem with your TV. Possibly the internal speaker connection?
Also try using another TV and the same connections - this will tell you whether the problem is with the signal coming to your TV or the TV.
P.S. You haven't "muted" the Telewest box have you?
