Does not respond to remote once remote turns TV on. Use Philips remote, RCA
unvirsal, and satellite remote. All have worked before, all do the same
thing, once they turn on the TV, the TV does not respond anymore. Changed
batteries in all remotes with brand new ones. Can still change channels and
adjust volume with the TV set controls.
If I unplug the TV for a half an hour and plug it in again, the remotes will
work fine for a couple of days, then the same thing starts to happen
again....at first intermittently, then all the time.

Any help appreciated.....
thnx
