Test the remote using a camera on a mobile phone: access the camera function on the mobile phone, point the remote's transmitter (front end) towards the camera lens. Observe the mobile's display while pressing buttons on the remote.

If the remote works, you should see a blinking spot on the display of the mobile phone each time you press a button on the remote - this is the light emitting diode inside the remote which can not be seen with our naked eyes because it is emitting infrared light, but the camera on the mobile phone is able to convert the infrared into visible light so you can see the flashes when you observe the remote emitter through the mobile's camera.

When you test the remote, you will probably notice one of the following types of behaviour:

1. the emitter blinks when you press ANY of the buttons on the remote that you normally use to control the unit - the remote is functional and there is a problem elsewhere

2. the emitter blinks only with some of the buttons that are normally being used - the buttons that should work, but do not, most probably have dirty or worn out contacts

3. the emitter does NOT blink no matter which button is pressed - there is a fault inside the remote

----------------------------------------------------------------------------

So, if you can see the flashes, the remote is functional, but the unit you control with it does not respond.

There can be several causes for that:

--- the remote is not programmed with the right code (only for universal remotes, if the remote is original and it came with the unit, then this most likely isn't the case).

--- there is a problem with the unit that is being controlled with the remote. Some possibilities are a bad infrared receiving sensor, bad solder joints on the sensor, a problem with the sensor decoder or other components associated to the decoder, bad power supply to the sensor or/and decoder, a problem elsewhere in the unit).

----------------------------------------------------------------------------

If you see flashes only with some butons pressed, but not with all of the buttons that are normally used, then some of the buttons may either have dirty contact points or the contact points are worn out.
This would require either cleaning the rubber keypad of the remote and the underlying circuit board with some alcohol and cottonwool, but if that doesn't do any good this means that the rubber pad contacts are worn out (they can be renewed with the remote repair liquid kit), an alternative is to replace the rubber keypad or the entire remote.

----------------------------------------------------------------------------

If there are no flashes whatsoever, no matter what button you press, then there is actually a problem with the remote. Some possible problems and solutions are:

- a dirty battery connector contact (clean the contact)

- a broken wire from the remote's battery connector to the circuit board, either at the connector side or at the circuit board (test with an ohm meter or a continuity tester, resolder or replace the wire or replace the connector, if and as necessary)

- a bad component on the remote's circuit board - there are not many, a capacitor, an IC (chip), a quartz resonator, an infrared emitting diode, maybe a few resistors and diodes (see or test if any components are damaged or burnt out and replace if necessary - this requires some knowledge about electronics and some measuring equipment, an universal multimeter for the least)

- a bad solder joint on any of the above mentioned components (resolder bad joints if you find any)

----------------------------------------------------------------------------

Anyway, the most common problems with remotes that i've encountered so far were: bad solder joints on the pins of the infrared emitter and sometimes on other components, broken connection wires and dirty or worn out button contacts. Rarely, if ever, do i recall seeing an actually burnt out or damaged component - this stuff operates on a battery voltage which is somewhere between 3 and 9 volts so it would take some serious short circuiting or battery spillage to damage the components (anyway, spilled battery liquid or other sour liquids can be able to do that and can also severely damage the circuit board leads but this often means that the remote is forever gone).

I must apologize for this lenghty disclosure, i hope it helps somewhat.

regards

SOURCE: my samsung remote BN59-00852A just stopped

Try the instructions below. If you need to replace the remote, you can order one from:
http://www.remotes.com/remotes/servlet/rs?a=Search&o=c&uid=0&m=BN59-00852A&uuid=12967730823440

Before replacing the remote, try the following:
How to Re-Start Your "Dead" Remote Control This only takes about a minute and will restart 1 in 3 "Dead" Original Remote Controls. Good Luck!
Step 1- Pull the batteries out of the remote and leave them out until Step 4.
Step 2- Press and release each and every button one at a time on the remote control until every button has been pressed and released at least once!
Step 3- If your remote has slide switches, you must move the switch to each position then repeat the button pushing in Step 2.
(When you're done, be sure to put the slide switch in the correct position to operate the unit the remote came with!)
Step 4- Put the batteries back into the remote, being very careful to install them correctly.
New batteries should be used if you're not sure about the old ones.
Step 5- Try the remote.

Special Note:
If you have a digital camera, camcorder or camera phone you can test the remote to see if it is emitting a signal. Face the remote towards the lens of the digital unit until you can see the front of the remote. Depress any button on the remote. You should see a light (steady, blink or flashing) being emitted from the remote. If you do then the problem might not be the remote but the sensor on the TV unit.

Let me know if you have further questions. Please make sure to rate this solution. Thanks.

On my dish remote for tv 2 sat button stopped working and wont light up. all other buttons work. i have changed batteries but nothing changed. How do i fix this because i dont wan to waste money on an


Kevin rico,

I can definitely check this out with you. Does the SAT button light up when you press any buttons at all? If you press SAT, can you operate the receiver?

If neither of those work then the remote most likely needs to be replaced. If you would like to try that option, just send me an email at thomas.faust@dish.com and i'll assist you further!

Okay here's the fix.
Remove batteries. Re-install them wrong side in! Don't panic.
Reverse the direction of both the battery cells and install. Press "Power" button a couple of times and a few other buttons a few times. Then remove batteries and re-install the right side in.
Voila.

Philips hts 3544 remote control not working. it just stopped working, I changed the batteries but still nothing. please help.


Please check & ensure the infrared is emiting from the remote control. Though we cant see this infrared beam with bare eyes, there is a trick to do so in http://www.unique-stuff.co.cc/fixing_remote_control_check_infrared.html Most of the problems is weakened infared beam. Replace the batteries when needed. Hope this fix the remote control problem.

Akai KC02-E1 Remote with new batteries stopped working.


First, You cannot resync the remote, Second the IR sensor may be bad on the tv and third, the Digital bd may be bad. The IR sensor connects directly to the Digital bd which is the brains of the tv. Also, there maybe a stuck button on the remote or the buttons on the tv.

My Toshiba SE-R0161 Remote no longer works.


There is most likely nothing wrong with your remote. I just had exactly the same issue with my SE-R0161 remote. (I had just changed my remote batteries too and was getting a DR-2 code on the Toshiba DVR RD-XS52 unit's display.) My DVR and my remote had to be realigned so that they both have the same infared (IR) code. The remote and the DVR can have DR 1, DR 2 or DR 3 as remote codes. Pg 54 of the Toshiba Installation Manual explains how to align both your SE-R0161 and your based unit so that the remote works again. Good luck. Hope this helps.
