ck that batteries are installed correctly and contacts are clean. Put the old batteries in, if it is not trying to charge them, sounds like the charger is bad.

Mine is a bit older (2yrs), but I have exactly the same problem. Absolutely no sound from the headphones (no beeps). I also tried new batteries, but still nothing.

If you have a solution, let me know!

The green light signals that the unit is operational and working normally. The orange light signals that the sound is too loud and it will have to be compressed, again, normal behaviour.
The charge of the batteries is smaller than what it used to be in 3 cases:
1 - the capacity of the new batteries is smaller than that of the old ones. Compare the old and the new and this is the case then the only thing you can do is to buy another larger ones.
2 - the batteries aren't fully charged. You must keep them plugged in the charger until the red light starts to blink slowly. - about 16 hours for the first time then the same amount they were used.
3 - it's not just the batteries that age, the charges also does it. When that happens it can no longer deliver the full charge to the batteries no matter how long you keep them plugged so they just drain a lot faster - you must buy a new one.

Well it could be interference from the TV, computer, or other 900Mhz device (some wireless routers run on this frequency).

I'm currently dealing with the same issue myself, if I find a solution I'll post back.

Yes, you may. RCA connections are universal, just don't connect an input lead to an output jack: you might damage the jack.

I had that problem before. I thought something was bent. Actually all you have to do is make sure the headphone are pushed all the way up on both sides.

Hello Mike, your LG TV, does not have a headphone output, it only has optical fiber audio output
the options that I suggest are,
1) Connect the optical fiber output of the LG, to an AV receiver, that has said input and place the headphones in this equipment,
2) Buy an optical fiber to audio converter by RCA L and R and this is connected to a headphone amplifier
I send you links to the products that are sold in my country
I hope you solve your concern
Greetings Franco Dosil

Hi Edgar, it is important that the receiver works, because there is a dialogue between the transmitter and the receiver to confirm that they are on the same frequency, that is why the transmitter is blinking, you should repair the receiver and look for the frequency or channel that the transmitter is found and it will stop flashing

Hola Edgar, es importante que el receptor funcione, porque hay un dialogo entre el transmisor y el receptor para confirmar que est?n en la misma frecuencia, por eso es que el transmisor esta titilando, deber?as reparar el receptor y as? buscar la frecuencia o canal que se encuentra el transmisor y este dejara de titilar

You question contradicts

I can get sound out of the right side only.

Why no sound from right side?

Usually with headphones, it is a broken wire as they are very fine. Remove the ear pads and then get inside them. Or return them for service.

These are cheap, but I recommend Sanyo Eneloop as do Sennheiser or any good quality AAA Nickel Metal Hydride. The more MaH the better, and that is your duration of use.
