If your LG TV came with the IR blaster cable you will need to set one of the sensors in front of the sensor on your DirecTV box. Then go to your TV setting and select Video Input and Select the Input Port that your DirecTV box is hooked to. (In my case HDMI1). Then you will select that you are trying to sync your Service Provider and it will give you a list of device manufacturers. Select DirecTV limited and it will start to give you codes to try. You test these by trying the channel button up or down. If the channel changes you have found your code and you will click on "Yes" and you are ready to control. The "Guide" button will now bring up the DirecTV Guide and you no longer need the DirecTV remote.
Look at the back of the TV for the 'EXTERNAL REMOTE INPUT JACK (IR INPUT)'
Insert the mini headphone jack such as the MP3 player headphone jack into this IR jack in and out a couple of times to clean the switch contacts (the switch inside will select the front panel or the rear panel IR input jack signal).
Please try that to see ifit helps. Otherwise it can be the IR receiver board on the front of the TV or the processor in the main board may have failed.
First you need to figure out why your not getting sound. For the following don't use the remote. Turn everything on manually. Set the TV's input to the source you want i.e. DVD, input1, inuput2, etc... While viewing that source manually turn up the volume on the TV or receiver. If using the receiver, toggle thru the inputs untill you here your program. Write down the combination of equipment and there input settings. Bottom line we need to get your hardware working and understand the settings before we start working on the remote. Once the hardware is working you can then program the Harmony with the correct settings. If your hardware is not getting you audio please send me more information concerning your setup. TV type, Cable box, direcTV Reciver. I need to understand your setup before I can help you troubleshoot your system.
Hope this helps.
My LG TV stopped responding to the remote. A very helpful repair technician told me to stick a head phone jack in the sensor jack on the back of the TV a few times to clean out the contacts. Now the remote control works fine.
When you define different activities (such as Watch TV, Watch DVD, etc.) the remote will ask which of the TV inputs your device is plugged into. After programming, when you select the appropriate activity, the remote will automatically select the correct input.
