I've tried several remotes and I know the original one is working as I can see the IR light in a video camera but the TV will not respond.
My TV does respond to several channels from the remote , but not to all of them. Would this still be a problem of the RI componant?

tried with reset doesn't work, ok it could be the IR sensor at the front panel of the tv doesn't work. but before you replace it you need to ensure if your remote controller is working. have you tried to check the remote with camera trick just to know if the remote controller is sending light to the IR sensor of the tv.
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.
Is it one of hose remote that needs to be programmed for your TV or original reamote? 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.

Hi, I have a few things for you to try. 1. Your TV "6424TF" seems to have problems with its IR "Infra-red" sensor going bad. This is a common problem with your model TV. If this is the case no remotes will work on your TV. 2. Because I do not know the model of your universal RCA remote I cannot tell you how to program it.. please supply the model number of it. Try looking under the battery cover. might be an "RCR..." number. I need to know this because all universal remotes have different codes and programming methods. 3. To know 100% if its your TV that's bad you will need the original remote for your TV. I have already looked up your original remote and you can purchase a brand new replacement that will work right out of the package (assuming your TV IR sensor isn't broke) here: RR0108UD for all sylvania TVs . no programming is necessary for this remote.
To check to see if your device is controlled by a RF (radio frequency) or IR (infrared) remote:
Power the device on manually
Cover the front of the original remote that came with the device with your hand
Press any button on the remote that you know the device would respond to normally
If the device responds even when your hand is covering the front of the remote, the remote is RF and the device cannot be controlled by the Harmony remote
Another test that can be performed is using digital camera:
Using any digital camera, even one on a cell phone, camcorder or webcam, look through the screen of the camera at the front of the remote
Press a few buttons on the original remote
If you see flashes of light as illustrated, the remote is IR and the Harmony can control it. If the remote does not flash, this original remote is an RF remote and the device cannot be controlled by the Harmony remote
For comparison, try the same steps with a remote control that you know is working correctly, such as the original remote for the TV, or DVD player. You should see the IR emitters flashing when performing this test.
Most DirecTV receivers are able to be controlled with IR (infrared) or RF (Radio Frequency) signals. DirecTV receivers are usually set to be controlled by RF.
To control a DirecTV PVR / Satellite, it needs to be set to respond to an IR Remote: 1. On the original DirecTV remote press the Menu button 2. From the Menu press Select on Settings 3. Select Remote from the left menu 4. Press Select on the IR/RF Setup button 5. Use the Up or Down arrows to change from RF to IR 6. Press Select to save
Note: Some models of DirecTV may have different steps to enable IR. You may need to refer to your user manual
Harmony Remotes only control IR signals. so this is not the issue. The Harmony Remote should control the tv. the original remotr needs to be tested for IR or RF.
The device we are working on that is not being controlled by the Harmony Remote could be operating on RF (Radio Frequency) signals. Harmony Remote can only control the devices that operate on IR (Infrared) signals. Most devices that work on RF signals can be changed to operate on IR signals, and this usually could be done by changing the remote control command mode to IR from RF.
Please follow the steps listed below to test to see if the device is being operated on RF or IR signal: 1- We need to use the original remote for that device to complete this task 2- Using your hand or a thick and wide object (wall, pillow, book...), cover the top part of the original remote. In other words block the direct positioning between the original remote and the device. 3- After you cover the top part of the original remote (or used an alternate way to block the direct communication of the original remote and the device), try pressing the buttons on the original remote to see if it can still send commands that can be received by the original remote. You can try powering on/off your device using the original remote when the original remote is being blocked by your hand or another object. 4- If you still can control the device using the original remote without a point of sight, your device is being operated on RF signals. If you cannot control the device without a point of sight, then it is IR operated. 5- If the device is RF operated, please change the command receiving mode to IR rather than RF and test the Harmony Remote. 6- If the device is IR operated, please contact us again by replying to this email and let us know if none of the commands or some certain commands are not working for that device.
You can usually find the information on how to switch the device to be operated on IR signals rather than RF signals, through the user manual for your device, or by contacting technical support of the manufacturer for that device, or even sometimes reaching the information simply by doing a basic research over the internet.
Take the remote to your local Radio Shack and have it tested.. They used to carry IR cards and now have a pen-like tester that can tell if the remote is operating properly. Then, if you're sure the code is correct, you probably will have to have the IR detector in the Tv replaced...
If the remote is working but the TV will not respond, it means that the little IR receiver in the TV has stopped working. This is most likely because the receiver has burned out, but it could also have come loose. This is a very easy thing to correct, but the set should be serviced by a qualified tech.
