Question about Toshiba 32AV500U 32 in. LCD HDTV
It may be the IR receiver inside, but look at he back to see if it has a smll jack for External IR jack on the back of the TV, IF it does, try inserting in and out using small headphone jack to activate the switch inside the jack a couple times. You also need to verify that the remote is seding IR signals.
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.
