Tip & How-To about Televison & Video

Test you remote

Ever wondered if your radio / TV / Receiver / DVD remote is still working? You've changed the batteries and still it does not seem to operate. Test it like this : Using your digital camera or cellphone camera point the infra red LED of the remote into the camera as if to take a picture of the remote like this:



Operate one of the buttons on the remote and watch the remote through the viewer and you should see this:


The LED will be flashing rapidly if the remote is functioning. This is because the infra red signal sent by the LED is not visible to the naked eye but is to the camera's circuitry. Magic!! Now go try it. You know you want to. ;-) ps This will not work on your vehicles remote fob as it works with radio signals and not infra red light.

Just bought a Toshiba refurbished DVD/VCR player. The remote doesn't work at all. I've doublechecked the NEW batteries and tried a tip of pushing EVERY button with the batteries out. Any ideas


1) the batteries will be the same type and full charged
2) clean the contacts battery from dirty, dust, oxide or corrosion
3) retight the spring contacts battery with pliers for a GOOD contacts
4) open the remote.control and clean the keypads switch, from dirty, dust, oxide, Open contacts, or Bad contacts. they emite a good signal infrared from SYScon transmi vs Syscon receiver.
see the block diagram. If doesnot resolve the problem go to the repair shop TV for fix it.

My TV remote doesn't work. I changed the batteries but that didn't solve the problem.


The remote can be tested and Radio Shack and most repair shops have a simple card for testing---point the remote at the card and press buttons and the strip on the card either lights up or not.

Depending on the problem most remotes are fixable.

Stay away from "Universals" as they are usually trouble.

If batteries and remote test good the set has a receiver for the infrared signal the remote sends-

95% of the time it is the remote and not the receiver or set.

A precise model number would tell me of common issues with your set including the remote.
