No lights on charger sennheiser 45

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.

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

1. "Feedback" might have been intermodulation with another RF frequency. Make sure to use Sennheiser's frequency finder, or something similar, to determine what TV channels are clear. If you're using more than one transmitter, make sure they're all using the same channel bank.
2. The low bat/on indicator should be on solid if battery is good; and flashing if the battery is low.

ck that batteries are installed correctly and contacts are clean. Put the old batteries in, if it is not trying to charge them, sounds like the charger is bad.

Can you remove the rechargible batteries ? To try and reset them ? Or maybe replace them ? It sounds like the batteries have gone bad and not charging

There are 4 reasons why your unit is behaving this way:
1. Charger is the problem.
2. The docking station is the broken.
3. The battery is broken or not accepting charge.
4. The actual unit is the problem.
It is very hard to tell which one is causing this to happen.
Let us do some troubleshooting first:
1. Plug your charger in an A/C outlet and make sure the red power light (left) is lit, otherwise the charger or the docking station is broken.
2. You can test the charger with a multimeter. Unplug the charger from the docking station and measure the voltage across the outside and inside, it should register more than 5 volts DC. If there is a 5Volt DC the docking station is the problem otherwise the charger is broken.
3. If the red power light is lit and the status light (right) is lit too, your docking station is broken.
4. If the red power light is lit, dock the unit into the charger, the status light (left) should turn red when your battery is accepting charge or turn blue when your battery is fully charged.
5. If the status light will not lit at all (while the red power light is on), tap the screen while the unit is docked on the charger. If the unit will become alive, you need a new battery otherwise you need a new unit.

12 hours is very long time to charge, the status light should turn to blue in less than 2 hours especially for a new battery.

Hi I had the same problem and just emailed Sennheiser.Go to the menu on your TV and change the variable audio output to fixed. I use the headphones through the home theatre so the volume must be max on the home theatre and then you can adjust your headphone volume. It absolutely worked and I don't get anywhere near the static noise when I go to another room with the headphones on that I got previously. Also be sure your audio cable is plugged into the fixed audio output socket. I did not have to do anything with that.
