It's usual problem. Check resistance between charging terminals on the board. If it's short circuit then remove all caps between them. Remove charge IC ( small metal IC near microphone like N750 in T610).If you can't terminate the short circuit you need to do terrible operation. Connect the (+) of powerful external voltage converter to the (+) of board charging terminal and (-) to the gnd of board. The voltage is about 3,5 - 4,5 V, current variable 1,5 - 3 A. After preparing it turn on this hell machine for a few seconds. You may see a little smoke or some parts of your phone will be heating. Don' worry it works and tested on 4 Z600. Now you terminate short circuit and your Z600 will power on. Then repair charge circuit like GSM Coolhawk says and everything is OK.
Best Regards.
Looking forward to your answer.
