d. marcela alvarez,
Random channel switching or volume raising is not an indication of the IR issue for other 8 Series plasma units. The symptom for any issue I'm aware of involves not being able to to use the remote.
Do you live in an area where another person's remote might be changing your set as well?
our brand new plasma tv has a mind of its own. the volume goes up on its own, not such a big deal since we have a sony surround satellite speaker. but when the remote light starts going off, the channels start changing, the source changes from tv to cable to games back to tv and you cant even stop it! it does it all on its own! it is very annoying when you are watching your favorite show or a great movie and poof! the tv starts getting signals from God knows where. the only thing that "fixes" this is unplugging the tv for about 1-2 minutes and turning it back on, reset the source to our speakers and wait for it to happen again in an hour, or two if we are lucky.
I have ready other posts, and they only mention interference with cable remotes. but we do no have any problems with out cox dvr. we even took out the batteries from all our remotes (4) and the problem still happens. HELP PLEAAAASSSEEEEE!
