Re: Gateway FPD2485W - capacitor related?



Thanks for clearing that up, for some reason ground was on my mind even though I had the data sheet up.

Unfortunately I don't have a meter that allows me to set to 20 ohms, I have this clamp meter: [url]http://www.idealindustries.com/prodDetail.do?prodId=600-amp-clamp-pro&div=1&l1=clamp_meters[/url]

It has a function button that allows me to change from Ω to the following with each button press:

K Ω 0.000
K Ω 0.00
K Ω 0.0
M Ω...

Re: Gateway FPD2485W - capacitor related?



Hi, thanks for the suggestions.

1) Polarity should be OK, double-checked with my older reference photos and others in this thread and negative is toward the bottom of the board with the power connector. Soldering should be OK too, the inverter pads weren't as easy to work with as the power board and the caps were a lot harder to remove but I eventually got everything worked out. Pic attached at bottom, a bit heavy on the flux residue because I had a little bit of trouble getting all the old solder off. ...

Re: Gateway FPD2485W - capacitor related?



Ok limited success here. I went ahead and piggy-backed the new fuse on the old fuse. The new contacts fit within the old almost perfectly so all I had to do was solder them together. I used [B]jsog[/B]'s tip about holding the fuse in place with an exacto knife while I applied a bit of solder from a tinned iron and had an acceptable solder joint pretty quickly. Pic below.

I tested the new fuse for continuity and got a chime, checked ohms and got 0.3. Checked contacts on both the old fuse and on the new one and...

Re: Gateway FPD2485W - capacitor related?



Yeah I considered piggy-backing it on top of the old fuse or even using a few wires to solder them to the contacts, but my main concern is the fuse I have is rated 63V and the one I need is 125V. I've read its OK to use a higher voltage fuse in lieu of a lower voltage fuse, but generally not a good idea to use a lower in place of higher.

If you all think its OK to use the 63V fuse instead of the 125V I may give it a shot, otherwise I'll just place a new order with DigiKey tomorrow.

Thanks ag...

Re: Gateway FPD2485W - capacitor related?

Fuses arrived today, however I could tell right away that they weren't the correct size or specs. Far too small to be the same one, I guess I probably should've measured the dimensions first before ordering. I don't have a micrometer or anything but I measured roughly 6mm x 2.5mm x 2.5mm for the fuse's package size using a standard measuring tape. The part I ordered was roughly half that length at ~3mm.

Here's the parts I've narrowed it down to as most likely candidates, both fast-acting:

Re: Gateway FPD2485W - capacitor related?



Are the Nichicon's I installed suitable replacements then? Would it be worthwhile to replace them with those Panasonic FM at this point?

I did check with a flashlight and saw the Gateway splash and the 3 color bar when the monitor went into sleep mode in the middle of the screen, so good news on that front.

I went ahead and ordered 2 of the LF 5A fuses that PlainBill linked so hopefully that does the trick. I will update once I get them installed, any tips on holding the fuse in place while...

Re: Gateway FPD2485W - capacitor related?



Hi, just to clarify, I replaced the two caps on the inverter board a few weeks ago with Nichicon EW series from DigiKey: [url]http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en&site=US&KeyWords=493-1583-ND&x=20&y=20[/url]

I couldn't find suitable caps that lay down flat on the board but I have trouble in general finding stuff on DigiKey because I'm not really familiar with the various filter parameters to narrow down my searches. I'm pretty sure though someone here said the vertical...

Re: Gateway FPD2485W - capacitor related?



Hi PlainBill thanks for the reply. I mistakenly thought someone already provided a clear picture of the F1 fuse I was referring to but I went ahead and took a few pics just so there's no confusion.

It looks like the F1 fuse is marked "LF 5A". The fuse you linked looks spot on, I'm guessing the LF = Littlefuse.

I'll probably order 2 of these just in case 1 blows right away, do you have any insight on what was making the cracking/popping sound or was that the fuse itself before it blew?...

Re: Gateway FPD2485W - capacitor related?

Hi everyone,

About a year ago my FPD2485W started having a problems and I managed to bring it back to life by replacing the caps on the power board with the help of many in this thread: [url]https://www.badcaps.net/forum/showthread.php?t=8658&page=2[/url]


The monitor worked great for a few months, but then I started hearing a popping/crackling sound off of cold boots. After about 5 months, the monitor was dead again. Here's the latest symptoms and my troubleshooting steps so far:

Re: Gateway 24" LCD Model LP2407

Yep the post Wrog linked is very helpful, I'm pretty sure I used that one as well to get me started.

Separating the clips takes quite a bit of force and requires a tool maybe ~1" inserted that can provide enough leverage to separate the front and back ~1/4" to 1/2" before the clips detach. A putty knife or spudger would probably work best. Credit card is OK to get the initial separation but doesn't provide nearly enough leverage to actually separate the clips from my experience.

I ended up doing...

D'oh, sorry about that.....can't seem to edit my post, if a Mod can do it that'd be great.

Re: Gateway 24" LCD Model LP2407

Just wanted to update, but I did get around to attempting this on Saturday....and SUCCESS!!!!

Ordered from DigiKey on 4/20 and got all the caps in Thursday or Friday. Spent a few hours familiarizing myself with how to desolder caps and solder new ones. I picked up a desoldering plunger and iron stand and went to work.

Overall the hardest part of it all was removing the back cover....there's 3-4 tabs/clips on each side and its a real pain to get them all off without damaging the bezel.

As for...

Re: Gateway 24" LCD Model LP2407


D'oh, looks as if you're right, it was late when I placed the order and I think at least one of those was in my cart at one point, but the dimensions were wrong so I removed it. Oh well, I guess that cap 47uF cap isn't getting replaced. Thanks!...

Re: Gateway 24" LCD Model LP2407

This thread has been a great resource, I started having this problem with my FPD2485W where the backlight would not stay on after sleep/hibernation. Turning on the power would show the Gateway splash for 3-4 seconds and then it would flicker off again. Only way to get the backlight lamp to stay lit was just to keep turning it on and off...

So it sounds like its the capacitors from the power source, this list below was a great help as I just added the part #s verbatim. The only one I wasn't able to find in stock was:
