Why don't either the charging or on/off lights come on when my transmitter is plugged in?

Bad connections. Plug in and withdraw multiple times, It may serve to "clean" and polish the contacts. Hope it works.

Why are my sennheiser HDR 120 wireless headphones not transmitting any sound

You plug the charger base in the AUDIO OUT of the TV, not the headphones. You wear the headphones. You use the volume dial to lower or increase the volume. And don't forget to plug the base in a power outlet and turn on the headphones.

I have Sennheiser 120. Set it up right. One side or the other comes in clear. Never both sides at the same time.

I have a set as well but the batteries were weak and it was doing the same thing when they were new. Replaced with good batteries and that was the problem. if you try this and they still don't work then just return it for a replacement
