Re: Siemens Gigaset 4000 No Sound

I have the same problem. I have carefully taken the case apart and found that the earpiece is a separate part and connects by means of a couple of springs to the PCB. I tested the speaker and found that there is no continuity on a digital multimeter. I then held an earphone plug to one of the PCB lands and used a screwdriver to connect the other side. On pressing the green button- Presto - Dial tone!

So Now I just need to find a replacement earpiece. That won't be so easy.
To get the case apart, you will need a couple of table knives. i.e fairly thin blades, but not sharp enough to cut yourself. Start where one of the little holes is on the sides. The locking tabs are in 8 bunches on the front, you need to get the one near the little hole a bit apart, and work your way round. You may need to keep one gap open with one knife, while opening the next.
If I find a replacement part, I'll post it on here.

Re: Siemens Gigaset 4000 No Sound

Hi Krister,

It sounds from your symptoms (no pun intended) that your handset receiver/speaker has gone bad, or if you use a headset, the circuit might have gotten ripped open from tension from the headset plug. You can try plugging in a standard 2.5 mm plug headset into it (real common headset). My guess is that you will be able to hear dialtone using a headset and use the phone, but the phone will continue not ring or make key beeps.

Its fixable, but with the Siemens models don't let anyone try to open it. To work properly it needs to snap together tight, and guaranteed they will gouge the plastic and break the more than 10 tabs that keep it held snug together, there are no screws. The skill to open them without damaging them is proper training and muscle memory, which is reserved for the people that do it daily, plus if the plastic needs replacing it will add to your costs. Nevertheless, if you want it fixed, just google "Siemens Cordless Repair" and click the first or second non sponsored link to make arrangements to get it fixed. Good Luck and let me know if I was right about the headset audio.

Thank you for these instructions. I have Siemens geigaset A120 with three handsets and one of the handsets stopped working about a year ago and my previous tries att registering it at the base station had failed and I was about to give up and buy a new set for 80 Euro, but I decided to give i one more try at registering and it worked the third time around. So do not give up. When one your hand sets stops working (no dial tone and can not call from it) try re registering as described above.

I have exact same problem. Let me know if you find an answer.
No dial tone. I can call out and reach number (though no sound) so connections are there but just no sound.
For incoming calls, phone rings, pick it up, no sound.
Any solutions??
