I have the same problem. T68 won't switch on w/o charger. After switch on and unplug the charger, the phone works normal. If I press on/off button and hold, it switch on but if release the phone switch off.

Any idea how to fix it? which parts are fault?

Yes, there is a solution. It is similar to the Stuck-in-Handsfree solution I described a few months ago here. Wire a 2K2 resistor between vcc and pin 3 (I think).

Some of the phones need flashing and when it powers put in a sim card and keep it for some time.

The problem is the phone doen't respond to boot.

The BGA circuit that manages the charging is probably defect and need to be replaceced. That is if it only powers on with a charger. If it powers on but shuts down when you release the on/off button its the cpu thats need to be resoldered. In 90% the cpu is glued so you have to be very carefull when you resolder it. I dont have any pictures of the t68 board so i cant show you where these components are placed.
