LED TV providing RF interference?

I have a set of Sennheiser remote headphones that I use so I can hear the TV better. My TV in the sticks & bricks is an older LCD type and the headphones work just great. It uses the composite type connections. The TV in our rig is a 2-3 year old LED type. It does not have composite connections so I purchased a device that converts the digital output to composite. As I adjust the frequency to the "sweet spot" the static disappears but all I get is silence.

I suspect the LED TV is emitting an RF signal that is blocking the signal from the Sennheiser transmitter to the headphones. Could this be the case or am I way off base? Thanks for your replies.

LEDs that have built in voltage regulators can cause RFI to the point where they blank TVs, so it is possible that they are causing your problem. The solution is to either purchase LEDs with better engineered voltage regulators, or buy LEDs that have no regulation. You run the chance of burning out an LED while your batteries are being equalized (at 15+ volts) but the non regulated LEDs are inexpensive enough that if it happens, just replace it. I have non regulated direct from China at $2.00 each LEDs in some fixtures, and haven't lost one yet...
