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.
