Most likely water has gotten into the back of the handset and shorted the handset.

The cordless handset is not working


I suppose you put the handset back on the base unit so that they synchronise first.

My Sony SPP-930 cordless phone is about 15 years old. Just recently it stopped working. The base lights work fine but when I lift the handset off the base and press TALK, all I get is 4 beeps. I bought a...


The problem is in the main base, the cordless phone is unable to communicate with the base because it has stopped working that is why you are getting the four beeps. It is more cost effective to replace the complete phone system than repair. The only other possibility "and it is long short" unplug the power and the phone line cord from the wall and let it sit at least 30 minutes, this might reset the processor ic and get your system working again.

Ringer on Sony SPP-S2730


The main board in the base is bad, I was never able to pinpoint the bad component after changing a few circuit board parts.

I only saw this problem in the 2730.

The only fix I found while at the Sony Service Center was to replace the board.

Radio Shack sells a remote ringer.... You could hook that to the phone line and it would ring... Not the best fix but it would help... Even another phone in another room...

Sorry.... This problem frustrated me.... Wanted to find the fix... The board is expensive if avaliable....

Handset


Presume you are talking about the extra handset. Try placing the extra handset in the "main" base for 5 seconds.
