Hi my infrared remote control did not work from one day to the next. I tried each bugfixing from the operators manual. I changed batteries and the position to the receiver (receiver: sr4021). Are ther probably some button combinations on the infrared control panel which can connect it. How can i test whether the infrared control panel is damaged.?

Check the remote control for its infrared emission. Check it with fresh batteries. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience.

At first, you have to check whether the remote control is functional or not. Check its for its infrared emission. Check the battery contacts in its battery compartment for any rust or dust accumulated. Clean them well, insert fresh batteries and check for its functionality. You can get more details about how to check a remote control by check this. Some remotes will need cleaning. You can get these details too.

Hi Connie,

First of all, thank you for posting your question here at Fixya.
Please ensure that the battery is in good condition. Check the battery terminal for corrosion, Scratch it with fine sandpaper.
If the battery and its terminal is not the issue, please confirm if the remote control emits an infrared by pointing directly the sensor (infrared emitter) to your cellphone/digital camera. If it is working fine, you will be able to see the flash of the infrared through the screen of your camera. Watch the video below.




If you've confirmed that there's no infrared coming out from the remote control then this is an indication that the remote control itself is already faulty. Replace it with new one (part no. 0980-0305-3300 ).
If you can see the flash of the infrared, the IR board inside the TV is faulty. Please inquire at this link for replacement.

Hope I helped you.
Good luck and have a great day!

Hi,

To confirm if the remote control is working or not, aim the infrared emitter of the remote control directly to your cellphone camera, while pressing any button key you will see the flash of the infrared if the remote is in good condition. Click this LINK for more info.

If there's no flash of an infrared, the remote control is already faulty.
• Replaced the battery to ensure that the symptoms is not caused by low charged.
• Take it apart and check for bad solder joints especially on the battery terminal and on the infrared emitter.
• Ensure that there's no blockage on the infrared receiver in front of the TV.

If you've confirmed that the remote control is already faulty, click this LINK for the replacement.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

good day

2 common causes of malfunction remote control... first,is low battery or empty...if you have a multimeter tester set it to dc and check the voltage of your battery if it is on empty or low battery condition replace it

and secondly,when the infrared is defective...how can you determine?..if you have any digital cameras get it and point it to the top view of your remote then try to look the infrared bulb (LED)then press any button to activate the remote after look at your camera while pressing the remote if you see infrared lights up for every pressed..your remote is OK..if it is not lights up and your battery is good..replace the infrared to fix your problem

thank you and good luck

Are there other infrared sources in the new location that weren't there in the old location?

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.

Hello
You just check your remote control handset for its infrared emission. There is an infrared light emitting diode [LED], in front of your remote control handset from which infrared light rays are send to your TVs infrared sensor, fitted inside it, behind the infrared window on its front panel. Infrared rays are invisible to human eye. We can check if it is there by using a cellphone with camera option.
Put the cellphone in camera mode, and place your remote control's LED side towards its lens, for about a feet away or so, and when you push its each button, you can see an image in the phones' screen. If it is there, and still your TV don't work with remote control, TVs infrared sensor inside is faulty, and needs replacement.
If there is no infrared image from your remote control, you have to buy one new remote control. OK.

dont blame the receiver yet, the problem mostly comes from the remote control. it may be the infrared emiting problem. checkout if the infrared in the remote control is emited well. to see this infrared you can read the article at http://www.unique-stuff.co.cc/fixing_remote_control_check_infrared.html

good luck
