I was watching T.V. and when I went to change the channel, the remote control wouldn't respond. I changed the batteries (generic) & the new ones didn't make the remote work either. I hit the power button on the T.V. and it did turn the T.V. on & off & changed the channels. I think the bulb or the eye on the remote is the problem. I can't remember ever seeing the bulb actually lit up. It is dark, so it seems it would be red. It's an old T>V> & remote, but has always worked. HELP PLEASE.

You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site.

Pull out the power plug of your TV and don't use it for few minutes. Remove batteries from your remote and keep it without batteries for few minutes. After about 15 minutes your TV and remove both will work fine.

your turning section is not responding to any input, hence needs to be checked by a technician. every thing you have mentioned are controlled by one ic, with its respective voltages.

for some reason unknown, the laser or infrared diode has died
