We'd need to know more about the receiver than the mic, since it's the receiver that is muted. Muted means NO SOUND.

If your Sennheiser RS 175 TV headset has a green lit power light that blinks on and off and doesn't have any volume, here are some troubleshooting steps you can try:

1. Check the batteries: Ensure that the batteries are charged and inserted correctly into the headset. You may also want to try replacing the batteries with fresh ones.
2. Check the audio source: Make sure that the audio source is turned on and the volume is turned up. You may also want to try connecting the headset to a different audio source to see if the problem is with the source.
3. Check the audio cable: If you are using an audio cable to connect the headset to the audio source, make sure that it is plugged in securely at both ends.
4. Reset the headset: Try resetting the headset by turning it off, unplugging the transmitter from the power source, waiting for a few minutes, and then plugging the transmitter back in and turning the headset on again.
5. Check for interference: Make sure that the transmitter and headset are not too far apart or obstructed by walls or other objects. Also, ensure that there are no other devices nearby that may be causing interference.

If none of these troubleshooting steps work, you may need to contact Sennheiser customer support or take the headset in for repair.

Analog transmission are prone to all kinds of interference. Microwave ovens is notorious for this while it is being operated. Also the high voltage that TV creates are strong source. Flourescent light is also a strong source. Anything that produce hight voltages can cause strong interference. The other ones are somewhat neglible.

Some boxes have settings in menu if the outlet stays on with box being off.

I had the same problem when I plugged it into a new HDTV. The problem was that the sound on the TV was set too low. The transmitter has a feature that automatically turns off when the signal is off or too low. Try turning up the TV volume to a high/higher level and it should solve your problem. Using the headphone jack with the white input allows you to use the headphones while bypassing the TV speakers.

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
