Hi all - I've had my JVC AV28R25EKS for about 2.5 years and been very happy with it but it's recently developed a problem with the sound that makes it unusable. The picture's fine but there's either no sound at all or there's a REALLY loud sort of machine-gun-like beeping that can't be turned down or stopped without powering off the set. Just wondered if anyone else has seen (heard!) of anything like this and if people think it can be fixed via the service menu (just found out about that - thanks! - but am at work now so can't try it) or if I need to get it repaired. Thankfully it's got a 5-year warranty so that's not a problem, I hope... The problem mus tbe with the TV itself because I can plug in a spare portable and see all the usual cable and terrestrial channels and watch videos and DVDs. The weird things are 1) the problem started immediately after our 16-month-old stuffed a mobile phone into the video which is hooked up to one of the SCART sockets. Straight after that we lost the sound and after switching off and on again it came up with the blue 'JVC' setup screen followed by no sound/very loud beeping... Can a mobile in the video *really* screw up the whole set...? 2) at least one menu item has now disappeared - the 'Digital Surround' option has just vanished! Also, the 'Sound Setting' menu is different to that in the manual - there's no 'Stereo I/II' or 'Speaker On/Off' options but there are 'BBE' and 'Hyper Surround' options which I don't *think* were there before but can't remember. So.... helppppp please!!!
