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
