My mac won't power on

Hi all,

I had problems with the display case that started to separate from the screen. I followed your guide to disassembly the screen. The first time I used episodic bi component glue but it did not work. So I re-assembled the mac and It started regularly.

After some days, I tried to for the second time to separate the display and to glue the parts. This time the process went OK but the mac won't turn on.

I checked all the cables, I tried to short the 5th pin and the ground pin but nothing happens. The LED indicator for the battery is ok, the battery is charging too. In the mb near the charge connector, I measured voltages of (16 Vdc, 3,3 Vdc,dcc) and in the battery connector there are the same voltages.

Do you have any suggestion in order to diagnose which component might be in a faulty condition? As I said, no specific operation was made on the board.

If you need more information do not hesitate contact me.

Kind regards.
