Have a new Panny TH37PW7. V happy with it and the panny media box. Both the TV and media box came with remotes. All the media box remote buttons work but only a few of the TVs ones. This means I can't get pic in pic or to the TV settings menus to set up the screensaver. The TV hard buttons don't respond wither. Have been advised that the TV remote will work if the media box isdisconnected but I am worried I will lose all my settings. Any advice appreciated.
