FSP psu 150watt dead
April 15, 2018 05:44AM
I have an fsp150 1ade11 laptop charger and it`s dead i see 3 bad componenets a fuse a transistor and a resistor , the fuse and the transistor was replaced exactly the same as before. But i can`t find the resistor value i cant measure because it`s dead , and the marking on the top side was completly erased ,due to the burnout. The board name is : 76v0a 94v-0 and i can`t find a schematic for it, i tried 10, 100 ohm resistor but always destroyed.On the ac side i can measure 120v so the ac side is ok except the resistor.

thumbs up for the effort to repair the PSU.
Maybe you can try to use a potmeter? Begin with full resistance and slowly turn it until it works....
