Re: Gateway FPD2485W - capacitor related?

Just in case anyone has a Gateway FPD2485W monitor that displays symptoms like the ones I described at the top of this post. I thought I'd post a final update to let people know what they can expect if they decide to tackle this on their own. I ended up selling (for shipping cost plus a few dollars) this unit to a person who had much more technical know-how, and more time than I could afford. He was gracious enough to let me know what he found when he dug in. From him:



Lesson learned: it's likely to be more...

RacerX,
I have not checked that fuse. I'm not sure I understand how a blown fuse could cause the symptoms I describe (menus system slowing down, but still working; sync with signal slowing down, but still, eventually working, if the power cord unplugged/replugged). It seems like a blown fuse would stay blown and cause constant (unchanging over time) problems.

Well, it looks like it will go to the landfill. All the caps replaced, never helped.

Not worth anything else.

Just in case someone else gets the same symptoms.

Re: Gateway FPD2485W - capacitor related?



OK, I had a chance to take my processor board out. It seems that my part has the same 'feature' - making noise like something is rolling around.

I'm attaching a close-up pic of the part so people can more clearly see it.

I wish I could be more helpful, but I'm not even sure what a "data sheet" for a component is.

I think I will try replacing the caps on the processor board; mostly out of curiosity, and to try to save landfill space. I'll post again when I've got more...

RacerX,
It's kind of a pain to take apart the case. If you search, you'll find some basic directions online, but I never found any pictures.

Basically, you remove three pretty obvious screws on the bottom, then the four screws that hold in the metal plate where the screen mounts to the stand. After that it's nothing but prying and (at least for me), breaking some small plastic parts on the sides. I used two screw drivers on the bottom - put one in and then work along with the other. I had to pry much harder than I thought...

Re: Gateway FPD2485W - capacitor related?

For anyone interested...

I ended up replacing all the electrolytic capacitors on the power supply board.

It didn't change anything.

I think, as I said in my first post, that this might have something to do with the processor, or processing board. The main symptom I'm thinking about is the fact that the menu system is slow and getting slower.

Oh well.

If anyone else has any ideas, I'd be happy to hear them.

Re: Gateway FPD2485W - capacitor related?

seanc,
thanks for your advice. I'm assuming you mean start with replacing the capacitors on the power supply board. Is that right? Is there any particular reason? Is it just the easiest thing to do to rule out a problem there, especially knowing that Su'scom capacitors typically cause problems? Or is there something else in the symptoms that's making you say that?

Thanks for your input.

This is my first post, so thanks in advance to all of you that might share your expertise and information.

I have a Gateway FPD2485W that I've used for about 3-4 years at this point. It's generally been fine, but it's starting to act a little weird...

These symptoms seem to be true for both the DVI and VGA inputs. They also hold true across multiple computers - so I'm pretty certain it's not related to the computers or graphics cards.

When I turn it on, and it has a signal, it will take quite a while (30-40 seconds) to go through it's warm-up process...
