The culprit is a Panasonic TH 42PE30 television that has suddenly developed a picture / sound problem just on BBC 1. Signal quality as given by the tuning menu is good (9) for BBC1 and no other stations seem affected, although we did find the same issue with the BBC News programme (130).
The programme appears fine then suddenly there is a 'pop' sound and the picture disappears into horizontal / diagonal lines with poor distorted sound. It reminded me of the horizontal hold issues with good old 405 line valve sets, but that is a side issue. Picture is not pixilated into squares as can happen with poor signal. After maybe10 - 15 seconds it pops again and picture reverts to normal for another couple of minutes. I have tried an auto retune and also setting to shipping condition to no avail. Another TV running off the same aerial (but via a freeview box) is not affected. A TV on a different (dedicated) aerial is not affected.
Does anyone have any suggestions? This is puzzling me as I cannot convince myself that it is a signal quality issue. All help would be appreciated, Thank you. Phil
