I read a previous question where it was suggested to use a cell phone camera to test the beam on the TV remote sensor. How is that done? What if the TV sensor is not working? We've tried several replacement remotes as well as changing the batteries in our original; nothing works.

Re: Remote won't work
You can build a ir sensore box find parts at radioshack or you could open your remote clean contacs with mild soap and water nothing else and do not use any thing that may scratch then check to see if your (leds) light emiting diodes are broken of the pc board

Not very often, if ever. Here's a way to test the remote for operation. Turn on the camera on your cell phone. Aim the remote at the camera and hold down any button on the remote. If you see a flickering light coming from the remote, the control is working perfectly. Now hold down the button that doesn't work. If the light flickers, the TV sensor is bad. If the light doesn't work on the suspected button, then the remote is toast, but repairable.
093,028,082,073,000,019 are the codes to check with Coby brand TVs. If you wish to get more details, check this site. Pull up previous posts there. Setup code list and setup proceedings to
many popular brand remote controls are given.
Three digit, four digit, five digits and two-digit code list are there. Check the site with patience. Surely you'll get a solution to your problem. Search the site by 'Timeslide' option. It will make search easy. Or, type in the brand name to your device
into its search box, and press "Enter"
Please follow this procedure to find the exact problem.
Check the battery of the remote.If your battery is 1.5vdc x2,the reading should be 1.5vdc x2 also! or 1.4vdc,tolerance to response the remote.Replace the battery if it is below on the tolerance voltage.
Check the IR sensor using a digital camera or cell phone camera.
Place the camera in the front of IR sensor then push any of the button to activate the remote.If your IR sensor flashes on the camera it means you IR sensor is good if not flashes on the camera replace it.
I hope this information will be helpful.Thank you very much.
Hi, Two things are involved to cause that problem, tv remote control and remote sensor in tv. Upon verification of remote working, it would be confirm that remote sensor in tv is defective and need to be replaced. Remote control sends infra red light signal to tv and we can not see that light with naked-eye, so need digital camera or cell phone camera to see it by watching remote front through camera, press any keys on remote, if you see infra red light is blinking in remote front that means remote is working and remote sensor in tv will be replaced. If no light blinking on pressing remote buttons confirm that this remote is defective and buy new remote. Let me know if you have additional question. Thanks.
test your remote first by placeing in front of a cell phone camera and press any button on the remote and look for a blinking light on the cell phones lcd screen (same as taking a picture) if you the blinking light then your infrared remote sensor is bad inside the tv. part cost about 10 dollars.
As far as I am aware, the code is only for preventing rated channel viewing. Can the TV be turned on/off with the remote? If not, either the remote or the TV is defective. Check battery, check TV/DVD/SAT switch on the remote's side or front, is there any switch in the battery compartment? If the battery is good and the remote is functional, you may check it by holding it towards the your cell phone camera while pressing any remote button. You should see a bulb lights when any key is pressed. Our naked eye cannot see it but the camera can. To make sure the test works, use another remote. If the JVC remote test fails with good battery, change the remote. If the test shows good, then the TV's remote sensor could be defective.
Evidently 2 good remotes point at the problem being the remote sensor on the TV itself. I have about 4 remotes I can adjust volume w/ including the remote that came w/ my samsung. The TV exhibits the same behavior w/ all of them.
Per the samsung site, the "test" for this (remote vs sensor) is to us a digital camera, (including the kind that's on most cell phones) to "see" if the remote lights up. Just point it at the camera/phone, and press any button. You should see a bright flashing light on the camera/phone's LCD screen. If not, REJOICE! All you need to replace is the remote or batteries in it. If you do see the light, good luck if you're not in warranty. I've been unable to find any procedures for replacing this kind of item.
YOUR REMOTE IS A TRANSMITER WHICH TRANSMITS AN INFRA-RED BEAM WHICH CANNOT BE SEEN WITH THE NAKED EYE THEREFORE USE YOU CAMERA PHONE TO TEST IF IT IS TRANSMITING A BEAM
POINT REMOTE TO CAMERA PHONE AND PRESS ANY BUTTON ON THE REMOTE. YOU SHOULD BE ABLE TO SEE THE INFRA-RED BEAM FLASHING ON THE SCREEN OF THE CAMERA PHONE. IF THERE IS A BEAM IT MEANS YOUR DEVICE THAT CAME WITH YOUR REMOTE IS FAULTY. IF THERE IS NO BEAM YOUR REMOTE IS DEFINETLY FAULTY. IF YOU FIND THAT YOUR REMOTE IS TRULY FAULTY USING THE PROCESS MENTIONED ABOVE THE POSSIBLE PARTS TO REPLACE WITHIN THE REMOTE WILL BE THE L.E.D, QUARTZ455MHZ PS PLEASE CHECK YOUR BATTERIES AGAIN.
