I have a defective remote control I try to check it thru my camera no light emerge in my remote control, please assist me where l can buy a new remote control, thank you

You can test the remote control using a camera to see if the remote is transmitting the IR signal. Place the remote control in front of camera and press any button, once you press the buttons you should see the LED on the remote emitting a light but that is only visible on the camera. If no light is visible, then the remote control is defective.. If light is light is present, then is IR receiver on the TV is defective.
Let me know if you require further assistance.

Did you check the LED sensor it is similar to a small bulb you can check it without removing it in the pcb by using a camera or a cellphone with a camera. Point the sensor in the camera then try to press any buttons then look at the monitor you will see a red light that glows if not your led sensor is defective try to replace it. Do not throw your original remote because it is hard to find a compatible remote control for your unit. Universal remote control has limited function not like the original.

Turn tv on manually.Test the remote control all functions are dead or some functions work other don't?Tries take the remote control parts and clean the inner rubbers buttons between the rubbers insulater and the remote circuitries board and the battery connections + - connections with some rubbing alchahol.Then wait awhile like 20 mins and putting it back together again and putting in new battery in the remote,it might work again.If getting the same result than the remote CPU chip is probally dead,remote control devices are very depended on it CPU chip.Try website like Remotes.com to buy an original remote for the replacement.

an easy way to check if a signal is coming out of your handset is to look at the end that you normally point to the sky box through a video camera or a mobile phone camera. these devices can view a much greater range of frequencies than the human eye so when trying to view infrared it looks like a normal white light through a camera. view the end of the remote thru the video camera and press a button like the volume on the remote as this will give a constant stream of data out of the handset. if no light is seen the remote is goosed. hope this helps

OF COURSE, THE OBVIOUS IS TO CHECK AND/OR REPLACE THE BATTERIES. SECONDLY, AND THIS IS A GOOD LITTLE 'TRICK' TO REMEMBER,AS IT IS A GOOD WAY TO TEST ANY REMOTE [I.R.- INFRA-RED] IS TO TAKE A DIGITAL CAMERA, EVEN A CELL PHONE CAMERA, AND AIM IT AT THE FRONT OF YOUR REMOTE. THEN PRESS THE POWER, OR ALMOST ANY BUTTON, AND OBSERVE THE VIEWFINDER OF YOUR CAMERA. YOU SHOULD SEE WHITE, PROBABLY RAPIDLY FLASHING LIGHT ON THE CAMERA. DIGITAL CAMERAS AND CELL PHONE CAMERAS USE A C.C.D. SENSOR, WHICH IS HIGHLY SENSITIVE TO INFRA-RED LIGHT, INVISIBLE TO THE HUMAN EYE. IF YOU SEE NOTHING, THE REMOTE IS MOST LIKELY DEFECTIVE. IF YOU DO SEE LIGHT, THERE'S STILL A SLIGHT POSSIBILITY THE REMOTE IS BAD, AS IT HAS TO OPERATE AT THE CORRECT FREQUENCY. THIS TYPE OF FAILURE IS NOT VERY COMMON, AND USUALLY OCCURS IN OLDER REMOTES THAT HAVE A QUARTZ CRYSTAL TO CONTROL THE FREQUENCY, AND USUALLY OCCURE WHEN THE REMOTE IS DROPPED. ANYWAY, IF THE REMOTE IS IN FACT DEFECTIVE, THERE ARE MANY UNIVERSAL REMOTES AVAILABLE RATHER CHEAPLY. IF YOU DO BUY A NEW REMOTE, TRY TO SEE IF YOUR SET IS LISTED, AND CHECK THE STORE'S RETURN POLOCY, JUST IN CASE THE REMOTE IS'NT THE PROBLEM.

If your remote control have display but cannot transmit signal to the unit. Confirm first if the remote is really the problem, using your camera or cellphone camera as your eyes point the remote transmitter to your camera and "on" the remote.

The unit can be operate without remote control, use the manual button located in the unit.

If the remote control have no display replacement of remote is recommended.
