Philips 32PT71B1 does not respond to remote
 

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

Have you tried to change channels/volume from front controls?
If the fault is only in the infrared receiver section, you have a small area
where the fault can be found...
Verify the voltage supplying uP and infrared receiver is stable, then follow
the remote signal from receiver to uP and ensure it keeps the same
amplitude.
