Re: ACER 5742 Dead M/Board
Replaced Pq51 desoldered pj18. Used power supply 18.5v 1amp. Turned on 18.5v on pq51 drain/gate /source also on pq52 source then nothing on drain of pq52. Moved power supply to drain of pq52 injected power as above sparks at pq52 drain power supply drawing 550 mAmps, put alcohol on board no obvious heating of components, turned off PS. What is the best way to devide and conquer this motherboard?
