Question about Sennheiser Audio Players & Recorders
I have charged my RS 175 for over 24hrs (for 1st time use). I can turn the headphones on (by holding the button for 2 seconds). This on/off button stays green. The battery indicator on the recharge base goes out - no illumination when the headphones are off the charger. When the headphones are on the charger, the bass and surround lights work. When the headphones are off the charger, these lights go off. The charger is sitting behind my television (less than 2 metres from where I am sitting). I have the TV sound set to Audio Out/ Optical. The optical cable is connected to the TV and to the charger. I have watched several YouTube tutorials - but still no sound from my headphones. Right now, the green light is on (headphones) the on light is blinking slowly on & off on the charger, the surround/bass lights are not on (charger) and the battery indicator is off (charger) I just checked the power source - unclipped the Aust. adapter, re-clipped and plugged into the surge protected power board and now there is no lights working on the charger. The TV is connected to the same power board and is working ok. Please help a technology challenged person use her brand new Sennheiser headphones... thanks Leanne
Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

sounds like your charging circuit isn't working or the adapter isn't putting out enough power or amprage to fully charge the battery, or you battery went bad. if the charging circuit is bad then so is *********** board, time to burry the system and buy a new one

I found the following:
Red light slow blinking: Battery Low, please put mouse in charger and charge;
When in Charger Red light Slow Blinking: No charging, please check and clean Gold Plated contacts in charger and Mouse;
When in Charger green light Blinking: Charging in progress
When in Charger green light Steady: Charging complete
When in Charger Red light Fast Blinking: Mouse detects overvoltage during charging! Please clean Battery contact inside Mouse, or replace rechargable batteries NiMh 1500-2100 mAh only

I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.

Testimonial: "worked like a champ!"
Mine is a bit older (2yrs), but I have exactly the same problem. Absolutely no sound from the headphones (no beeps). I also tried new batteries, but still nothing.
If you have a solution, let me know!

I will assume you have tried tuning them via the control mounted on the headphones and still get nothing from the left ear.
First try a different channel setting on the base and retune the headphones.. if this doesn't fix it..
Check all your connections.. at the headphone base as well as the source.
Also I suggest trying them on a different source.
Since you did not mention what the source is.. I will make a few additional suggestions.
If plugged into an amplifier.. try repeated switching between output sources.. If the amp is playing fine through both speakers.. pick up an inexpensive adapter that will allow you to plug the red and white rca jacks into a headphone jack, then try HP output. (some RS 120 units shipped with this adapter)
If the source is the television itself check the connections on the back.. and check your balance settings on the sets main menu.
Depending on how old the headphones are along with frequency of use you may need new batteries.
Make sure the batteries are fully charged.. remove them and test the voltage.. they can do this for you at Radio Shack if you don't own a volt ohm meter or some other testing device.
Replacement batteries are not that expensive.. just make sure you replace them with the exact type (AAA - NiMH) and allow plenty of time for them to charge before use (overnight)
This last bit of advice I suggest caution.
You can put a fresh set of AAA standard batteries in the headphones and test them.. DO NOT PUT THE HEADPHONES ON THE CHARGING CRADLE with these batteries or you MAY DAMAGE THE HEADPHONES.
In fact I suggest you place a piece of tape or something on the cradle before you do this to remind you.. once you finish testing the headphones with standard non rechargeable batteries .. again trying different settings and tunings the set.. If they work .. you probably need a new set of rechargeable batteries..
This is a quick and dirty way of testing/comparing.. but REMOVE the standard batteries immediately after this test. Placing the headphones on the charging cradle with standard batteries in place could cause them to rupture and leak into the headphones.. so again.. be careful if you decide to test them in this fashion.
