Hello to my favorite electronics forum. You guys helped me many times just by reading through the posts here. Thank you.
Now to the point.
My situation is this :
I have a HP Pavilion DV5 with no signal, fans spin up and capslock blinks with error code "General system board failure". These boards are notorious for their graphical chip going bad. So i did the usual re soldering and heating the vga chip (ATI) and the chipset also.
But now, when i power it up it , the lights come on and after 1 second they go off. During that time the mosfet in the picture below heats up tremendously. Tested it with a Dmultimeter between pins 2/3 and 6/7 and the reading is 66.7 Ohms. THe mosfet is this.
Also found out that the capacitor (also in the picture below ) reads a "Short" when testing with diode (acoustic) test. Is the capacitor causing the heating of the mosfet and my whole problem?
Also how can i recognize what type of capacitor it is ? (How many Farads, voltage? Are these 390 2.5v the values of it? or is it something else?)
Any help of any kind will be greatly appreciated. Thank you.
