My sennheiser hdr 130 has no sound even though it has lights on its based and it is connected to my t.v. what is the cause of this problem and the solution?

yes they do, if its connect via usb cord to pc or wall wort
does no sound cause from no power light (blue light on right side) if so you might have bad batteries this has happened to me before , there not user replaceable either bummer

The system is working in the 860 Mhz range, so not that common. Most of the time it is cheaper to by a complete new system then to tray to buy components. Just keep looking in the thrift stores you find a transmitter for this headphone for a good price.

If you twist the earpiece,one of them has two NIMH AAA batteries ,worth checking out if these are gone ,which is what happened to me.I was about to bin my rs130's and just stuck two new rechargeables and the earphones are working again!!!!!

As for $20 dollars from sennheiser for replacements!?!?!?
You should pick up two NIMH batteries for a couple of bucks on ebay or amazon.DO NOT USE ORDINARY BATTERIES!!!!!

The batteries are at end-of-life OR your charger has failed.

Forst replace the batteries... they are MOST likely bad. Charge the new ones before using.

I had complete silence on an HDR 130 headset (no beeps, nothing), but I solved this problem using a solution posted on another thread. Unplug the base, take out the batteries and wait 30 seconds. Reconnect it all and listen. Mine started working immediately!

Actually, I didn't fix it. I thought I'd go to the shop where I bought it first.

I had a similar problem - after owning them for 4+ years, no sound we coming out, and no beeps -- nothing. The lights on the charger stand were on though.

I tried buying new rechargable AAA batteries and they were NIMH (nickel metalhydride?) and still didnt work. I borrowed a friend's pair of NICM (nickel cadmium?) AAA rechargables though and the problem was solved!

So, it would seem the some of the new chargable battery types might not work in older models of this unit (which is also called the RS 130 now in the US and Cdn web sites).

Hope this helps!

Did you try to remove the batteries and at the same time unplug the power of the base for 30 sec ?

These systems have some signal detection, so needs an input to fire it all up. That is the same for the greenlight, when initially switched on for my HDR 120.

Try to remove the batteries and at the same time unplug the power of the base for at least 30 sec. then replug and reinsert the batteries. That did the trick on mine.
