I am trying to hook up my Sentry wireless H0802 headphones to the TV. I have the transmitter plugged in and working, and the cables from the wireless transmitter plugged into the audio-out jacks in the back of the TV, but all I get on the headphones is static, no sound. Any suggestions?

You must have wireless transmitter provision in your TV,to get connected to Headset.
Or you may buy suitable external wireless transmitter and connect it to your TV ,audio output and receive audio,in your head set.

Instructions
1
Set up the transmitter. Wireless headphones rely on a transmitter that sends audio via infrared or radio waves to your headset. Use the digital audio output (coaxial or optical), RCA outputs (red and white) or headphone jack on your TV to connect the transmitter. The connection will depend upon which outputs are available on your TV and/or the transmitter.
2
Use an RCA-to-headphone adapter. If you don't have a headphone jack on your TV and the transmitter includes only a headphone connection, connect an RCA-to-female headphone connector. This will allow you to plug the wireless transmitter into the female headphone end and then hook the RCA ends into your television's audio outputs. You may also need a 3.5 mm (mini jack)-to-1/4-inch adapter if the headphone plug on the transmitter doesn't match the television jack.

3
Set the transmitter on top of, or next to, the television. For infrared transmitters, you'll need a direct path between the headphones and the transmitter. Placing the transmitter on or near the TV will allow you to take advantage of the clear path you already have.
4
Plug in the transmitter and turn it on. Charge the headphones if necessary.
5
Turn on the headphones. Adjust the volume and settings and you're ready to watch TV.

good luck

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.

it was free,save them for parts

I had the same problem with Brookstone wireless headset the only solution I found was plug in the red and white connectors to your cable box it works perfectly that way. Just make sure the red cable connector from the transmitter is connected to right red input connector on the box. I have a Comcast cable box. Now I need a solution for them on my PS3?

It works, Its that I just needed to find an Audio out port. (which I currently dont have due to lack of a cable box in my room)

I don't think the 12V power pack is the problem. Generally there would be a regulator on the plug pack input to the transmitter (as power packs are notoriously bad at voltage regulation).

My guess is it an 'earth leak' between the TV and the transmitter via the audio lead. Does the powerpack have a earth pin. If so, are you able to plug it into an non-earthed power outlet.

If this isn't possible try removing the ground connection from the audio lead.

It could also be a bad audio lead.

Is the TV mono and the transmitter stereo or visa versa? You may need a mono to stereo lead.

Hopefully something in here will help.

please rate this solution?? hahaha lol here you go

The H0900 should come with a mini-plug adapter. The headphone jack in my TV was deeply inset, so I kinda reversed it. The adapter plugs into the transmitter, then the Red/White plugs, into that, then the long end of the cord into the TV.

Works fine for me. My problem will be posted seperately.
