while adapter applied the motherboard starts with just a flash green light for a half of a second then shutts down.
I found short to the ground in +5v net. (attached boardview).
here is the list of the chips connected to the +5v net
First i removed D4503 and D4705 diode but short is still there.
Then F5202, result the same,
THEN PC9108, the same, capacitor is ok,
then MOSFET PQ9104, mosfet is fine, short remains,
U5208 ans R5236 are not soldered on the board.
R5710 is ok, short remains
What remained is SL3102, SL4701 and J4901
SL3102 is connected only to the J3104 (backlith connector) but i dont see any damage there
SL4701 is connected to J4901 , dont see any damage there...
So i dont get it? where is the short? how is this possible?
