My tv wont work with the remote i can turn on by hand but remote wont do anything it has new batterys and the red light goes on

Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

2) If the remote checked out OK, then look at the back of the TV for the "REMOTE INPUT", use a mini-phone plug and insert the plug into the remote input jack in and out a couple times to clean the switch contacts that select between the front IR receiver of the TV or the rear panel IR input jacks.

My MKJ40653802 remote won't work even after putting in new batteries.The TV is hooked up to sky and that remote works fine + the Tv works on the buttons but not on the remote.Any suggestions


This only takes about a minute and will restart 1 in 3 "Dead" Original Remote Controls.


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. (no light means bad remote)
If you do then the problem might not be the remote but the sensor on the set.

IF this does not work then;
you can turn the set off and unplug for about an hour to allow any EPROMs to reset. Next plug back in and try the remote.
If this does not work it

My lg doesn't work with any remotes! I checked my lg remote - put in new batteries (correctly) - and no change. I reconfigured my directv remote & nothing happened. At this time I have to turn tv on...


This TV may have IR remote input jack in the back (the size of small headphone jack), when the external remote receiver is used, it will shutoff the remote receiver in the front of the TV, this jack has a switch inside which can get corroded if its contacts are not activated once in awhile. You can plug in a small headphone plug into it a couple of times to see if the remote will work again.

And here is how to test the remote to see if it still putting out the IR signals.
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

The remote no longer switches the tv on or off. is it a problem with the circuit board in the tv? is this repairable?


Does other functions work, if it does, the more likely to have worn out carbon pad on the power button.

My remote stopped working... I tried to reprogram my ATT universal remote then tried the remote that came with the tv. Neither is working.


The IR receiver in the TV may have gone out, but check the remote signal first.

Whad code do i hse to control my sanyo dp19649 tv


Hi! I will be more than glad to assist you in this concern. this are the tv codes for sanyo. 542, 589, 590, 591, 592,
609. this is how to reprogram you remote to the sanyo tv. you need to press and hold the tv button that is on the upper portion of the remote, on the right side of the sat button. wait until all mode lights lit up, once all lights lit up, release it and then press number ex.. 542 then followed by the pound button, then you will see that the pound button will flash 3 times, it means that the code is program to the remote. note: while your doing the reprogramming of the remote you need to be in front of the tv about 2 to 3 feet away and the tv should be on.. granting u try all the code and none of them works.. try to scan the code of the tv by pressing and hold the tv button wait until all mode light lit up, then press 500 then pound, tv button will flash 3 times, lets say the last code is 500 and it did not work, press again the tv button and wait until all mode lights up, press on the re tv button if you have, but just incase u have only 1 red button for the power, press it once, then press the up button every 1 sec for 5mins. once the tv turn off then press the pound button and the tv button will flash 3 times, it means that you got the code for the sanyo tv, to check the code: Press the POUND (#) button twice. The mode button
flashes the number for each digit of the device code, with a pause between the groups of flashes. A quick flash is for zero. For example, if the code is 570, the mode button flashes five times, pauses, flashes seven times, pauses, and flashes once quickly... lets say that this remote works before with the sanyo and suddenly it quit working , pls call 1-800-333-3474 and ask for the replacement for the dishnetwork remote, remote is bad. please feel free to get in touch if you have any query..
