I got my mom a pair of Sony TMR-IF240 cordless infrared wireless headphones to watch TV (she is hearing impaired). They worked beautifully in her house connected to a LCD flat panel TV. I just moved her in with me and tried to connect them to a plasma flat panel TV. All I get is buzzing. Unfortunately, the manual is at her home in another state.

I tired connecting the AC power to a different outlet and I tried replacing the RCA cable. Neither made any difference. Any ideas?

Here's a manual for a later model, might help.

Thanks, Chas. None of the troubleshooting info helps. All I get is buzzing.

I took them upstairs and conencted them to a different flat panel LCD TV. They work beautifully. So I know they work. Unfortunately, I need them connected ot the plasma TV.

There must be something that's causing interference near the plasma TV. This TV is conencted to a digital cable through a DVR. I also have a VCR and DVD player/recorder connected to the plasma TV or DVR.

Maybe check the manual for the TV?

I have. Shows diagrams on how to connect everything from timing lights to food processors. But nothing about headphones.

You need a line filter. http://en.wikipedia.org/wiki/Line_filter They run around $40-$50. If you want to go the cheaper route, pick up some shielded cables. http://en.wikipedia.org/wiki/Shielded_cable

Try connecting each side separately of the audio from the tv. Or try connecting to the audio out to the vcr or dvd.

Unplug the VCR audio cables and plug the headphone audion cables into the same AUDIO OUT jacks on the TV...
