Panasonic HDTV 10801 BBE TAU

Unplug it for a few seconds and
plug it back in if this doesn't
do it the call in a technician
may be HV or PWR Sply problem

We own a Panosonic HD TV model 10801. It is hooked in to a cable box, and also to an hd sound system. To operate, we turn each component on individually through the cable box remote. Likewise, to turn off we do each individually.

Here of late, when you go to power one component, the button actually turns on something different. For example, if I power up the HD sound, and then try to turn on the TV, the buttons actually end up turnif off the sound system. Likewise, if I try to turn on the TV on the remote, it may actually turn off one of the other components.

When I reboot the cable box, things work fine for a few days. Then, we are right back to the problem. Is there possibly a software conflict through the cable box, so that when they send updates, it creates this problem? Any ideas?
