Re: Dell 2007wfp - 2 sec to black
Toasty: I fixed the wiring myself and used some liquid electrical tape instead of silicone which cures in 15 minutes. I am typing on it right now. Working perfectly. Thanks much guys.

Re: Dell 2007wfp - 2 sec to black
So I opened the LCD and lo and behold the wiring is damaged on the top right corner (same corner with the arcing sound). See attached pic. Any good place to get replacement ccfl other than [url]http://www.ccflwarehouse.com/[/url]. Thanks Guys.Re: Dell 2007wfp - 2 sec to black<br.... Thanks Guys.Re: Dell 2007wfp...Leave a comment:

Re: Dell 2007wfp - 2 sec to black
Hello,
Although the monitor was viewable after a couple of power cycles, it now always goes back to black after 2 sec. So the capacitor replacement did nothing. Is there any way to confirm this is a ccfl problem if i have no spare ccfl? Should I replace the capacitors in the power supply?
PlainBill: I tried to measure the transformer secondary resistances but I don't have any continuity across any of the transformer pins? What am I doing wrong?
ThanksLeave a comment:

Re: Dell 2007wfp - 2 sec to black
Update:
I replaced all 5 caps in the inverter with Panasonic FC series caps. All went well. When I powered up the monitor I heard small arc kind of sound from the monitor's upper right corner. The backlight flickered at the same frequency as the arcing sound. Once the ccfl "warmed" up the backlight stopped flickering and the monitor seemed to be working normally albeit some sound from the same corner/ccfl. Turns out now, everytime I power cycle the monitor the ccfl flickers, some times even going 2 sec to black, when it does...Leave a comment:

Re: Dell 2007wfp - 2 sec to black
I've posted the pics to the forum. I dont have an extra ccfl so cant troubleshoot with that. Where exactly can i measure the tranformer's secondary voltage?
Thanks....Leave a comment:

Yes I have looked for it online. It is P/N: 5EL2J04011. I is/was listed [URL="http://www.lcdrepair.us/2007fp-inverter.html"]here[/URL] for 49.99. I am unable to find it anywhere else.Re: Dell 2007wfp - 2 sec to black

Dell 2007wfp - 2 sec to black
Hello,
Recently m 5 yr old Dell 2007wfp developed to what is described around here as the 2 second to black problem. After reading about this problem I begun to think it is an inverter problem. Unfortunately inverters for this monitor are not that cheap or plentiful so I came here to see if I could repair it. I opened the monitor to inspect the inverter and power supply. See pics hosted [URL="http://postimage.org/gallery/4s4aw9d3c/"]here[/URL]. I don't see any bulging cap and I would like to know if I really should go ahead and replace all 5 inverter caps. Let me know...
