I've just encountered a problem with my Yamaha RX V357 sound when accessing the Sky + TV Guide or recorded programme playback I get terrific static thru the centre speaker. Once the programme is in normal play mode the static disappears and its OK in normal Sky and annalogue programme mode. I do not get the same problem when accessing Sky + TV Guide etc when I switch off the sound from the amp and go to the built in TV Sound which is why I think the problem is with the amp. I would be really grateful for advice to solve this irritating problem.

I'm not sure your amp is at fault. Are the two connected by digital link or analogue? If the Sky+->TV link is in analogue and the Sky+->Yamaha is in digital, then it's a problem with the digital connection. The Sky+'s digital output and the analogue ones run along different lines at output and one could be off and not cause problems in the other.

I suspect the Sky+ box has problems. Is it a problem that resets itself after a few seconds? If so, it's a muting issue; if not, it's the digital output failing to lock on in certain modes. If the amp was randomly losing digital lock, the amp might be at fault, but it sounds like the Sky+ box has gone all crazy.

The words 'get a new one from Sky' spring to mind.

Thanks for the reponse Alan and sorry for the delay, have been away. It was the Sky Box, I had further problems with the Sky Menu other than the one which started the post. The Box has now been replaced and the problem has resolved.
Thanks again.
