Helo. I'm working on a JVC AV27790 made in 1996. I do not have a service manual. The set never shows a menu or a volume bar when pushing the front buttons or with the remote. When pushing the channel +/- it will change but with a 1 or 2 second delay. The same thing happens when pushing power on/off. Otherwise the picture and sound are good. Does anyone have a suggestion?
