HP 2335 monitor
hello,
I have a problem with an HP monitor. When I put the power cable, I have the green led OK on the front and my screen is black. I can push every button on the front, but nothing happened. I think that the problem comme from the inverter, but i never seen this board before.

Re: Benq Power Supply DS-1107A
My monitor run for a few second before coming black, so backlight working briefly. but since I changed the 4 transistors, it didn't run and became very hot like I describe in my last post.
I resolded the 4 transformers. I didn't use the same transistors because i can't find, I used mosfet, this one:

I think they are good.
I try to change the capacitor and I give you result after.

Re: Benq Power Supply DS-1107A
I have replaced all the transistors, but I have 2 that become very hot, the 2 are at the left of the transformers, the self(solenoid?) above the transistors was very hot too.
No output at all !!Leave a comment:
