Hi, My LG LST-6100P Set Top Box remote has stopped working. It is sending IR commands but nothing changes on the unit. The unit works ok using my Logitech remote. It looks to me that for some reason the remote has changed the IR commands it sends out. I have an IR extender and if I hold the remote up to it you can see that the remote is sending out IR commands because the light inside blinks. I have tried another Learning Remote using the ir sent from this remote and this also does not work.

See step 2:
LG:
1) Test the remote:
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.

Hi,

Yes the digital set top box should work in the UK. When it arrives just re-scan for the channels as the UK are currently in the middle of a digital switch over.


Regards.

First I would check if the remote is momentarily sending out the volume command or is it sending it out continuously. You can use this trick with any IR remote. Using a digital camera with display, point the remote at the camera and press the volume button on the remote. If the IR led is working then you should see it glow on the cameras screen. When you release the volume up button, the IR led should stop glowing. If it does not stop then you may have a sticky key or a problem with the program. If it shuts off then the Harmony is functioning ok and there is a problem with your receiver. Another way to test this is to press the volume up button and then immediately cover the remote with a blanket or take it to another room or remove the batteries. Let me know if the remote is continuously sending out the Volume command or is it momentary.
Hope this helps.

Hi. A lot of DirecTV remotes actually use UHF, which is a form of RF. The Harmony remote can only send and capture IR (infrared) commands. Make sure you have your DirecTV device set to receive IR, and if you have an IR remote, or can set your remote to IR, then it will work.

Hi Rod,

Thanks for Using FixYa. If its a 4:3 normal TV or a wide 16:9 TV then you can view high definition picture by using the ARC button on your remote control to change the wide mode(Auto,Letter Box, Pan & Scan). Also check its free user manual for more information.

Please do accept the solution if the issue is resolved or else revert for further assistance.

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.

To remove the LST-4100A commercial control interface from the television you need to follow the commands below.

1. Power on television.
2. Press and hold "MENU" for 10-15 seconds.
3. Quickly press "2-6-6-3" and then press "ENTER"

If you have done everything properly, it will bring up a small menu in the top left hand corner of the television. Kind of a hidden menu.

4. Arrow down to the menu option that says "D Box" and turn the option to "OFF".

Now turn off television and completely disconnect the LST-4100A. In fact, throw it away. In the trash is where it belongs.

Your television will now operate like a normal television purchased from a big box store. You should run an automatic programming setup for grins upon completing.

Enjoy your new NON-commercial lcd television.

try code 10178

first i assume you are trying to watch the unit through AV. If this is the case, turn on unit, press "Display Format" on the front of the unit, keep press it till you have "YPBPR" displaying, press select on front panel, next press "Display Format" again till you come to 576i, press select. Now press menu and it should display. If this problem occurs with HDMI, simply change the display settings to HDMI, and 1080i. Hope it helps, Murder-face.

cap-grant, my friend has the same problem with set top box. When I phone maker I was told it is due to poor and weak signal. You must have 80% signal strength to maintain good picture. When signal strength dropped picture would freeze and had to be turned off at the power point to restart as nothing would work. So I guess what my experience says is you may need better aerial to boost signal and prevent dropout Leonard210
