Depends which wireless headphones you have. Most headphones do not use WiFi, they use Bluetooth or 2.4 MHz RF. Usually a wireless headphone set will have a transmitter plus the headphones. The transmitter usually connects to the TV either with the analog L+R ouputs or the stereo headphone jack.
Normally the wireless headphones have a transmitter that send audio via wireless to the wireless headphones. The transmitter needs to be plugged into the headphone outlet on the TV. This will switch off the speakers on the TV and sends the audio to the wireless headphones.
First, determine if the TV device is putting out sound by plugging in a headphone into the audio out of the TV. If audio is there then the transmitter and wireless speakers system may be at fault. You can also plug in a CD player playing a disc into the transmitter to see if that source then transmits the audio.
My speakers were working fine on my TV, I disconntect them, then when I re-connected the transmitter no signal is received and nothing is heard via the spearkers either.
Speakers have a unique RF frequency that needs to pair with the receiver (kind of like a blue tooth headset with a cell phone). At times, the signal may reset, so, you may have to go through the initial pairing sequence. Try this: 1. Unplug rear speakers 2. Make sure the sound signal connector is plugged in to the back of the system properly. 3. Press and hold the ID button for 3 seconds until the blue LED light flickers. 4. Connect the power chord to the rear speakers.
Hi, I had the same problem, it seems to be a design error of LG or a typical problem with some component in the wireless transmitter. It is basically caused by the transmitter heating up, leading to a clock drift with the result of the receiver losing the signal. I tried to cool the transmitter in the fridge before using so it will run for about half an hour before producing this error (depends on the room temperature as well). My solution is to remove the plastic case of the transmitter unit and place it in a cool place where it does not catch heat from other devices. Without the case it does not overheat and also takes less space, just be careful if you have children. I placed the naked Tx unit behind the TV so it does not matter. Hope this works for you as well.
