I have a 1690 that I have had for 18 mos and really like it. But some how I pushed the remote buttons incorrectly. Now when I use the menu button, the highlighted area scrolls on its own to the various functions and will not stop. this keeps me from using the functions. Anyone have any idea hon how to cure this? I have tried umplugging the unit to let it rest but it did not wrk. Thanks! al
