I have a HP LCD monitor with benq power board. Last week, when i turned it on, the backlight turned off right away. I can see the image moving on the screen using flashlight.
I found out the whole thing was made by benq and there 're some discoloration( lititle darker) near the transfomer .
I borrowed a ESR meter from my friend and all the caps are still within range. I suspect it is the transisitor that near the transformer.
The transistor is FU9024N , a p-channel transistor, and i only have a multimeter
Anyone know how to to test it using the multimeter?
