My remote doesn't work anymore for my 19 inch dvd/tv digital labs tv

If it is an infrared remote... you can test it with a digital camera by turning the camera on and pointing the remote at the camera, then look at the viewfinder while pushing any button on the remote and if it is sending a signal you will see it illuminate in the viewfinder. This help identify if it is the remote or the device that is not working.

I have a Currys Essential TV and the remote does not work. Help! Model is C15DVDB10

Have the remote tested--simple and most shops have a tester you point the remote at and press buttons--tester will flash if remote is working(can test every button on the remote).

Some digital cameras will also do this when remote is pointed at them you will see in the LCD screen a flash if remote works.

If the Remote is good----the remote receiver in the set is bad.

The remote sends a infrared signal to the front of the set (little dark or clear lens) and the lens there (cannot be dirty or blocked) sends it inside the TV for it to be processed.

Infrared receiver doesn't wokr

Call Andrews Electronics and give the make, model number, and the circuuit board location (label printed in PCB next to IRreceiver). To check if your remote is transnmitting, point it a digital camera (cell phone camera will work just fine) and look at the screen on the camera while you press the buttons on the remote. The infrared light will appear as white on you camera display.

Missing plastic circle: remote doesn't function

If the remote sensor cover is missing on the TV, the remote would still work but you may get other effects like the TV changing channels on it own.
This is due to stray infra red signals.
If it's not working at all I would suspect the remote control handset.
You can test it by pointing it at a digital camera lens and watching the display screen on the camera.
You should see white light comming from the remote when you press any of the buttons if it's working.
Digital cameras can see infrared.

Quasar VV-1302 13in TV/VCR unit. Remote stopped working

Test your remote by placing it in front of a video camera or web cam if you have one.. Press the buttons and watch the cam to see if you see the light coming from the remote.. The camera lens merely slows the light to a visable spectrum.. If no light your remote is not working... If light replace the sensor in the TV..

My remote control does not work

You could have a defective IR sensor in the tv set that sends the infared signal to the MIcroprocessor IC. These are something you cant just replace, as it needs to be trouble shot with a scope to see if theres a data signal comming out of the sensor and if there is it could be a bad solder connection somewhere between the sensor plug to the Main IC. Also could be the B+ that supplys voltage to the sensor. Unless you have had electronic repoair experience, You should have a pro assist you with this repair. Sorry I couldnt assist you more with this . Good Luck
