Hi

I have here one Nokia 6280, its problem is that it doesn't power on! When I plug chargar in, it shows charging! And when I put f-bus cable for flashing with mt-box, phone power on normaly, and working! Power swith is good, problem comes from the motherboard.
So what can it be?

Waiting for your replas, thanks in advance.

Refit flex cable or change it. (When powered up with cable and pressed power button it gives you profiles?)

Flex cable is good, 'cause I tried with another good (up part: lcd + flex cable) 6280 and phone still same, so problem comes from the motherboard (down part).
When I press power button, it doesn't give me profile.
Thanks for fast replay :)

Simulate battery ( mean Vbat, BSI and GND ) with external power supplay and look over current when you press power button ...
