I have a 1230 set with 31234 as key 0 with a ringing appearance on key 5 of 34567. When 31234 rings, it isn't ringing on 34567. Why?

SOURCE: Pantech C120

change the speaker on the phones and also have the ringer check on the main-board.

SOURCE: 0 and - keys fell out!!!!

hey
This could be a little difficult to explain.. coz the white ring acts as a spring and putting it back on is not hard but difficult to explain.

See first of all on an acer laptop a key has 3 components
the key
the white thing (which holds the key in place)
and a black soft thingy (which actually gets pressed wen u press a button and acts like a spring)
first of all the white ring can be removed and refixed easily .
Youll see 4 small hook like structures on the palce where key needs to be placed ... first place the white ring over there, the white ring has 2 things which come into one another. (try referring to the key where in the white ring is still in place).
now if the black spring like thingy is removed from its place, place it in the center of the ring and put the key on, try moving the key a little, if the key and white ring are put correctly, this will produce a click like sound showing the key is locked by the white ring .. if the white ring is dismantled into 2 parts it could be a little tricky to put them back on.. in that case i guess ull have to check a fixed ring and try and replicate the same for this key

SOURCE: MY PHONE WON'T RING. WHEN I SET THE RING VOLUME

replace the speaker of the phone

SOURCE: I cannot hear my phone ring. It is set to high

Look for a setting that changes the ring from vibrate to ring. It's a setting different from that of ring volume.

SOURCE: will not ring for incoming call only viberates

You should try to put it on only ring cause some phones have issues simular to yours.
