Default Re: Dell 2007FPB teardown

Still have not found anything. All the resistors check fine and have same value as resistors in the same position of the second PWM controller which works fine providing both +3.3 and +5 V. But the +12 V is jsut still not there. Something is making the PWM go into 0 % switching mode.
