Did you verify that the remote is putting out the signal?
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.

You can try www.shopjimmy.com to see if he has the IR receiver board in stock if it is bad for sure.

    Took a while to get back, but yes. I tested the remote and I do see it working through the camera.
    I called Philips and they had me put a piece of tape over the ir sensor to block interference, and that also does not work. Is this a hard piece to replace? Could I do it?

    Replacing the IR receiving module is just a matter of taking the TV apart and install a new assembly, the problem right now is that I cannot locate the replacement board for this model.
    To be sure that the module is bad or not is to check the signal output of the receiver with an Oscilloscope or just put in a new board which usually runs about $20.

    I have just discovered that I had actually bought a service plan for this set! And I am still covered, yeah! Will follow up when tv is fixed.

There is no TV button to press on rc-017 remote, setup instructions say press on tv button till led lights up.


If you mean the Coby RC-017 remote, it is not a universal remote that can be set to control any TV or other device. This remote will only work with the TV for which it was originally programmed. I believe it should work for a TF-TV1511, if both the remote transmitter and television IR sensor are working. Assuming you have the correct TV, try just pressing the power button.

I hope this helps.

My remote no longer works with my tv. I think its the ir sensor but I don't know what it looks like to replace it. I have another tv of the same model for parts and need to know what the ir sensor...


You can confirm your remote's IR output by pointing to the phone camera and if the remote works it will be seen as a flash on the camera. Now after confirming the remote then the the IR detector on teh TV can be checked. It is always mounted on the FRONT panel and is a small DIODE mounted to face the IR panel ****. It is easily seen and can be checked using a multimeter . In the Ohmn's range in one direction a flash of light will increase the flow and continuity when the probes are held across the diode. If teh IR is good then it is a fault on the processor controller.

I have a 60 inch lg tv. The remote just stopped working Put in new batteries. Tv button lights up on remote but will not turn tv on.


Let me know model number of your 60 inch LG tv to find out possible cause of no remote operation.
I do not think that IR receiver is bad in your tv. Regarding dusty IR receiver lens, you can confirm it by sending remote signal by very close distance to tv.
There are few other possibilities of no remote operation problem instead of bad IR receiver.

Its remote control sensor is not working


I have had to replace that IR sensor several times and I have also seen the wiring for the sensor being pinched by the back cover. You can call 1-800-samsung for the nearest service center.

My IR remote no longer works in another room


Dawn,
If you want a remote that works via IR to control the satellite receiver you will need a IR only. The IR/UHF type only transmits signals to the receiver by UHF and the IR portion only operates the peripherals in the room such as the TV and VCR. There are some remotes that come with a kit that can change the remote to work as an IR only. I believe you have a TV2 remote and want it to work further away from the receiver particularly the room the TV is in. If this is the case you may have have to change the remote address of the new remote to match that of the old. You can do this by taking the number one remote and pressing menu-menu. Now take the new remote and press and hold the SAT button in the upper left of the remote until all lights across the top light up. Now key in the two digit number on the tv screen at remote address for tv2. Then press the pound sign and the SAT button will flash three times then press the record button and the TV2 icon should flash. Now you can cancell out of the screen on tv one and try the remote at the TV2 location. I believe this will fix your issue if not let me know. Thanks for using Fix Ya.

The IR reciever should be in the front of the set where the remote IR window is located.

I can tell you that there is a lot more that can go wrong than just the IR reciever. There may be a buffer amp along the way to the uPC, or there may be a fault with the uPC itself. The fault may also be a cold solder connection, or a missing supply voltage to the the IR reciever or to some of the components involved in the IR signal process.

In opening and working on your set, there are serious safety issues involved. You should be giving the set out to a trained and experienced TV tech for proper and reliable service.

Not receiving IR Commands from remote.


replace the IR sensor...I don't have a part number for it..but I have seen IR sensors grow either weak..or fail totally..also you'll want to verify that the remote is working...you can buy an infrared detector strip from radio shack for a couple bucks...all you do is push power on the remote continuously..and hold the detector strip up to the front of the remote..if you see a red flashing on the strip..the remote is transmitting..if not..the remote has low battery..or has taken a dirt nap.......

Remote control issues


Yes it is a quessing game. If we experts do not have the set in front of us to trouble shoot, but I will explain the process. First off to work on any tv set, your going to need a schematic diagram or should have one, or it will be a crapshoot. Next set up your osilliscope and multimeter. First check the B+ going to the IR sensor. If its at 9 to 15 volts, and is clean without distortion, Im thinking that is ok, but check the manual to see what it is suppose to be. Once the B+ is confermed good. Place the scope probe to the data output on the IR sensor while pressing a remote funtion. If the date is clean looking and is present then the IR sensor is good. If it is not good or noisy, replace the IR sensor. In the event its there, trace the data signal with the assistance of the schematic diagram, to the microprocessor, through all the jumpers and plugs and componets, like coupling capacitors or resistors, as I have found bad solder connections on the route to the microprocessor. If the same data signal is on the input of the microprocessor remote input, that is on the data output on the IR sensor, then replace the micro. This way of troubleshooting, has in the past, fixed every remote problem I have encountered with a remote intermittant, or no remote operation. Good Luck
