How to repair a Remote Control that is not working properly

When you have a remote control that is not working properly---works but some buttons either do or do not work correctly the most common cause for this is something got spilled on the front of the remote--it does not have to be a large amount to cause problems.

The way all infrared remotes work is there is a circuit board inside with black carbon lines etched on it---this includes lines for each function the remote has.


The buttons on the outside of the remote are actually one large rubber like mat and on the bottom side are coated black buttons---when you press a button on the keyboard the button part on the bottom of the mat touches lines on the circuit board and directs the remote to send a infrared signal to the unit it controls.

In this situation you have two choices:

1.) Most remotes can be taken apart and cleaned for this problem--I have done hundreds of them.

a) Once you get the remote apart (the hard part) the rubber mat should lift freely off of the circuit board---if you have to peel it off and feel resistance you will see whatever residue of what was spilled and got under it; it gets between the mat and the circuit board.


b) The surface of the board where the lines are can be cleaned with denatured alcohol.

c) To clean the mat: remove it completely and with a small toothbrush and dish soap gently wash it in the sink with warm water. Then dry it with compressed air or a hairdryer set to air only. When it is COMPLETELY dry put it back into the face of the remote.

d) If there was a spill into the remote it is also a good idea to clean the face of the remote where the buttons protrude and dry it completely before you put the mat back.

e) Put the remote back together and see if it now works.

Your second option is to borrow another remote for the same kind of unit and see it works normally--if it does and cleaning does not fix the original remote--YOU WILL NEED to buy a new original remote for the unit.

I stay away from "Universal" remotes as many either will not work or be missing several features the original one had.

If a KNOWN good remote does not work it is possible but very unlikely that the problem is in the unit the remote conrols.

See attached photo
of a typical remote taken apart--note the lines on the board and the bottom of the buttons on the keypad.

Neverclean the bottom of the buttons with anything except soap and water asany chemicals can damage the black conductive coating on the bottom ofeach button--it will not hurt the lines on the circuit board!

Please make sure your remote control is working properly.
It is pretty common for remote control buttons to stop working after a certain time period or due to excessive usage.

My remote for my Kdl 40w5500 tv doesn't work properly?the volume,programme,theatre & on/off buttons work but none of the others do????????


Hi,
Common cause is the liquid substance from old batteries of remote control. Just clean the rubber contacts and printed circuit board inside of your remote control with alcohol and cotton or cloth, let it dry for few minutes, then re assemble your remote control and it's done...

Menu Scrolls Uncontrollably


The most common cause of the problem is a stuck/shorted button either on the television or on the remote. The worst case scenario is a faulty key control board. Remove the remote control battery or put it away from the television. Press the menu button on the television and check if the menu scrolls by itself. If yes, the DOWN button is stuck or shorted. You can actually hear or feel it click when pressed if it is not stuck.

Open the back of the television to gain access to the key control board. You can either repair/replace the faulty button or replace the key control board. Remove the screw holding it to the television casing. Disconnect the old board and install the new one.

Replace the remote control if the buttons on the television control are working properly.

remote code for dish network remote to control olevia tvs


Please follow the steps below to program your remote control to equipment other then your DISH receiver:
Note: If you start this procedure and at any time and do not press a button within 20 seconds, the remote will end the procedure automatically. Simply start over again. Use the TV button for your TV, the VCR button for your VCR or DVD player. These Mode buttons are located at the top of your remote control.
1. With the desired equipment on, press and hold the correct Mode button until all mode button backlights illuminate, then release. 
2. Press the numbers 5-0-0 on the remote control. 
3. Press the Pound (#) button on the remote. 
4. Press and hold the correct Mode button until all mode button backlights illuminate, then release. 
5. Press and release the Power button on the remote control. 
6. Press the Up button once a second while pointing the remote at the desired equipment. If the code for the equipment comes up, the equipment will power off. 
7. Press the Pound (#) button. If the code entered is valid for the remote, the mode light flashes three times. 
8. To verify the code works try several different functions for that equipment. 
We cannot guarantee our remotes will work all other devices. If this does not correct the issue, unfortunately our remote will not work for that device. We apologize for any inconvenience this may cause.
