Re: dell E173Fpf burnt parts
Yes, your right. I used the diode function on my multi meter. The voltage drop across the junction was my second thought of what the reading actually was. When the probes were reversed I had an open circuit. Thanks for the insight. I'll continue to examine/test and post my results as they become available. Thanks for all the replies.

Re: dell E173Fpf burnt parts
Thanks so much for the replies. Good point about specific pictures of my board, all kind of small changes could have occurred. When I get a chance I will post them as you suggest.
The resistance of the transformers are just what you said, 529 and 530 ohms for T1 and T2 respectively. I tested C6 And C26 with a cap meter after pulling them out of the board and got around 210uf each so I think their good and I put them back in.
I tested the Schottky Diode (D854) and got .194 (ohms I believe) from each outer leg to the inner cathode, and...

Re: dell E173Fpf burnt parts
Hi. I have the same problem, no display, but my power light is a steady green. I swapped in a good power/logic/inverter board and the display came up just fine. Your picture is exactly my system board. On the bad system board nothing seems to be blown out or burnt. The person I got the display from said the picture just quit. I tested the typical 220uf 25vcaps and their good. Sooo, I think the low voltage power supply is ok, good power light and the flashlight test reveals an image on the screen, but no back-light. Since both back-lights quit together,...
