Re: Dell 3008wfp faulty power supply

Good Eye

Sorry I haven't responded in a bit, been on vacation.
I had a chance today, tested with a multimeter and the F1 fuse looks to be the culprit. I lightly soldered a connection to bridge it for a test, and booted up the monitor.
And... Display!

A very bad and weird switching between a full white screen; a half screen with a very messed up display, and the other half black.

I took a picture.
It's a step in the right direction, tho not sure if it's repairable yet. Going...

Re: Dell 3008wfp faulty power supply

Thank you for your persistence in the troubleshooting of this issue. I really do appreciate it.

Currently, I did only a visual check of all the components, on each board. Nothing looks discoloured or bulging. I haven't done any multi-meter testing, as I am not quite sure where to start.

The symptom is, monitor responds to power button. When I turn it on, I can see the back light power on, the screen is dark (but lit up), and I have no display. I should expect to see a Dell Splash logo, or even menu selection when I...

Re: Dell 3008wfp faulty power supply

Took a little vacation and came back yesterday.
Decided to heat shrink and electrical tape the wires apart just to test out and see if this would fix before I sought a more permanent solution.

Turns out, the wires were either a symptom of another problem, or when they touched, they took out something else.

Since the problem is not visual (no bad caps) that about does it for my electrical troubleshooting skill.
Any suggestions?

Re: Dell 3008wfp faulty power supply

Right? Isn't that strange?

I will double check when I get home today, but when I was looking at it earlier, it didn't look like I could pop those that easily without breaking somethings. The side in the photo is easy enough, but the other side is a very tight 'ribbon like' connector.
But I'm always willing to try something new. Having a good one sent to me was just going to be the easier option for me Less work.

I will try to repair, and send you a PM, Lumberjack, if i get defeated with my current cables....

Re: Dell 3008wfp faulty power supply

Hey, I took apart a 3008wfp yesterday, found the issue in the attached photo. I have never seen cables do this before, so I was quite disheartened when I realized this was the source of my 'monitor turns on but no display' issue.

Before I go and attempt to reheatshrink this cable, does anyone have a spare one, or a project 3008wfp that they gave up on, that they would be willing to sell me this cable from?

Hoping for some Luck!
