    Thanks for the help. Unfortunately, I tried the factory remote as well as unplugging the set for an extended periood to reset it. No Luck. Next step is a tech since I lack schematics.

    Ain't it a shame that our parent's tv sets lasted for decades and we can't even gt a couple of years of trouble free service from these Far eastern pieces of ****.

    I have the same problem. The TV works good except the remote (not any universal remotes work). I took it to a repair man and was told it would take about $200 to fix. Is there anyway I could order the IR sensor module and fix it myself? Do I need schematics? Where would I get them?

    I have the exact same problem with my ir in my set. I'm absolutely sure it's from the set and not the remotes. Send me the scematics of the television so I can fix it. The part would be nice to if you would sell that to me instead of the certified repair. I bought the tv and should have boiught the right to service my own and the scematics. a package deal. Either we come up with an easy fix or I'm going to have to buy a new TV. Oh and it definately will not be another toshiba. I loved this TV but, there is always something to ruin it.

Well finally after trying everything else short of replacing the ir port or hitting it with hammer. What I done was drill a whole in the IR port screen about the size of a pencil so I could look inside.Well low and behold the remote worked from that day on. i don't know if I shook something in place or or the ir port was blocking signal. Either way i'm glad it works.

After exhausting all other options, I have decided to buy a different brand TV.

A universal remote is not a reliable way to test a remote control. If you can have an original remote this is the best way to test the remote function of the set. Or, if you have another set that is the same model as yours to test a universal remote, then the test would be acceptable.

If the remote has failed on the TV side, this can be from a number of problems in the set. It can be the remote IR sensor module itself, or one of the buffer amplifier stages on the way to the uPC, or the uPC itself. In some models the buffer amp is built in to the IR sensor module.

Without properly troubleshooting this fault, there is no possible way to actualy determine the point of failure. More than 90% of the time, the failure is the remote. Remotes get dropped, and abused often, and therefore they are subject to a high degree of failure.

Did you try unplugging the set from the AC mains for at least 15 to 20 seconds? This will cause a reset to occure for the uPC. If the fault is still there the set and the remote control will need a proper follow-up to service it.

Remote control not working


Have the remote tested to see if it is sending signal (infrared is most common) as most shops have a tester you point the remote at and press buttons and the test unit reacts.

many digital cameras can also in a very dark room be tested in the same way, push buttons with remote pointed at the camera and look for a tiny flash in response on the camera display

Other possible reason is a bad remote receiver but that rarely happens.

Remote won't work. Tried new batteries, reprogramming, etc. Universal Remote doesn't work either. LG #42PC5DC


Hi,
To confirmed if the remote control is working fine, aim the remote control sensor(IR emitter) directly to your cellphone camera. While pressing any button key on the remote control, you can see the flash of an infrared emitted by the remote control if it is working fine.


If you've confirmed that the remote control emitted an infrared but still the tv won't communicate with it, this is an indication of faulty IR sensor board of the TV. Check if there's an obstruction from the IR receiver in front. Keep away all of it, clean the plastic window of the IR receiver with soft clean cloth.
If the symptoms still persist, you have to replace the IR sensor board. Check the actual part no. of the board before ordering.

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

The remote won;t work


If it's a "Universal" remote and you've changed the batteries, you'll need to reprogram it according to the make/model of the remote. A remote that came with your receiver....

1. Check batteries, they may be dead or dying.
2. Is something blocking the remote receiving window on the receiver?

Remotes use infrared light to transmit to their matching devices and MUST have a line-of-sight path to work properly.

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.
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.

Remote control dosnt work on this tv


I have the same plasma Pioneer tv. I also tried a replacement remote and no fix. I replaced the infrared receiver module (~$4 from Radio Shack) on the TV, yes it involved taking the tv apart. Voila, now I have two working remotes.

Remote does not open garage door


It sounds like the wall button has the lock feature engauged.

Is there a small green LED flashing inside the wall button?
Push and hold the lock button for about two seconds and the LED should stop flashing. This will unlock the garage door opener and your remotes should start working. You may have to reprogram your remotes and homelink again since you triedprograming in the lock mode.

Good luck.

PANASONIC COMBO TV DVD VCR,REMOTE CONTROL NOT WORKING,NEW REMOTE CONTROL STILL INOPERATIVE,SUSPECT INFRARED RECEIVER IN TV,NEED SCHEMATIC OF A PV-DM2792 TKS


You can try replacing the remote receiver inside the set. This should be a small silver box located in the front of hte set. It should have 3 leads soldered to the board. The part number is:
LSSZ0004 and costs about $5.

Infra Red LIGHT OUT


Hi, Based on your trying of different remotes, your conclusion is basically correct, however, it is very rare for the infrared receiver to go dead (or at least the sensor itself). Should this still be the case, there is no other way but to open the TV unit. Since the placement of the infrared receiver is to the front of the TV, chances are that what your are thinking "take the entire set apart." is the only way to do remove the infrared receiver. A guess would be the sensor which normally is available even in RadioShack. Your best bet may be to seek the services of a qualified professional willing to undertake component level repair rather than modular/PCB replacement. At times it may just be a loose connection inside the TV or no low B+ to the infrared receiver module/circuitry. Alternately, you can try to "borrow" an original remote and see if that will work just to really confirm. Some instances of this problem in some other brands/models got solved by resetting the TV (unplug for a couple of hours). Hope this be of some idea/help. Pls post back how things turned up or should you need further information. Good luck and kind regards.
