Re: Dell 2007FPb - No power at all
Thanks, have seen those pics/diagrams before, just not sure what to do.
I followed budm's link to photobucket pics for the 2007FPb pics and tried to measure the violated written on the circuit board. As for the diagram two if those points correlate to the labels written on the circuit board (C44 and C60), but I cannot find a C58.
Putting multimeter to the fuse, I get 0 ohms. I assume that means it is okay.
Testing the diodes I got from this link. Not sure if it is correct or accurate.

Re: Dell 2007FPb - No power at all
zero,
Thanks for the response. I have looked and am not finding what I need. I am not the most knowledgeable but can test things if I follow directions. I have no idea what the tests might be.
Did you find a thread that did a step by step for the main usb board?Leave a comment:

Re: Dell 2007FPb - No power at all
Glad to see there has been some activity here, I got side tracked with other issues. I have not made any progress, but picking up from post #43 above, I get
19v = 19v
12v = 0v
5v = 0v
3.3v=0v
Any new thoughts?Leave a comment:

Re: Dell 2007FPb - No power at all
Maybe replace ALL the capacitors? Anyone?Leave a comment:

Re: Dell 2007FPb - No power at all
In all honesty I am not sure where I am in the process either (e.g. newbie). I tested some voltages as posted. I am not sure the LCD screen is good because I can not get any power to register on the switch or screen. Any help is appreciated.Leave a comment:

Re: Dell 2007FPb - No power at all
Anyone have any more ideas? Or is this thing headed to parts (if I can confirm which ones are good) or just junk it. Anyone?Leave a comment:

Re: Dell 2007FPb - No power at all
Well, apparently I can. I thought it may have been a burn or something indicative of a bad board.
Anyone else have any ideas?Leave a comment:

FD3 to FD8 all read around 90 Ohms with leads in one direction, open with the leads switched.Leave a comment:

I have not, what exactly am I testing? I see the diagrams, but not sure what side or how to test.Leave a comment:

If I can get another monitor up and running, I can take that one apart again. I checked and I do not have a picture of it.Leave a comment:

Re: Dell 2007FPb - No power at all
Not sure if I did this right, but was checking voltage two ways, between the two leads of the capacitors and also by one lead of the capacitor to the ground.
C44 and C60 - no voltage.
Could not find a C58, but C50 - no voltage.
U2, U5, U13 - no voltage.
J4/J9 pin 8 had no voltage.
However, the 19v from power supply is making it across to the logic (?) board and then across pin 11/12 to the USB/power supply board and then across the 3A fuse.Leave a comment:
