Re: Dell E172FPB - power supply board

Hi,

About the nickname -- I just picked it randomly (sometimes you have to wonder what goes through your head... ) Here's a couple of pics of the power supply board. I've inverted the picture of the underside so it matches exactly with what you're looking at on the top side.

Any ideas on how to bypass inverter circuitry? I just need power to the pins on the left that go to the logic board.

On a side note, I think I can see what causes the failure: it looks like one of the transistors on the far...

Hello,

I recently acquired a 17" Dell E172fbp that turns on for 1 second then goes black. Now I'm planning to use just the LCD screen for a homemade projector, so I don't care about the back light. I'm wondering if I can replace the built-in power supply board with something else, like a couple of walmart adapters or a computer power supply. This monitor has 2 circuits boards: one for power and one for the LCD. They are coupled by 10 pins. 2 pins are at 5V, 2 are at 3.3V, 4 are ground and the last two energize at 2.45V and 3.14V when I push the power button.
