|  I think T20 uses the same board as T28... so I think you have to change the audio IC, it's a BGA Ic, just under the key "2" on the keyboard. (I don't remember the exact name, maybe RDP1011120/SC).<br />On ericsson T28 data sheets is called N800. <FONT COLOR="#ffff00" SIZE="1">[ 22 November 2001 13:47: Message edited by: D-Brain ]</font> |
