Re: 2007 Dell XPS 410/9200 with Bad Caps
I completely agree, a 25w iron is not ideal for this job. It's too bad the 45w iron I found in the storage unit had a bad tip. If that's not bad enough tips aren't available for this iron anymore. All said I feel lucky to have a positive result....Leave a comment:

Re: Failed UCC and Rubycon replacement on a Dell XPS410, equivalent?
Ok so I went with the Poly caps, and they made it here Saturday afternoon. I installed them right away. It was a pretty challenging install since I only have a 25w soldering iron. I had some difficulty clearing the solder from the lugs in the circuit board but managed to get them cleared out and the new caps installed. There were traces on the board near the lugs that were very small and looked easy to damage or burn through if I wasn't careful, but I managed not to goof any of them up.

Re: 2007 Dell XPS 410/9200 with Bad Caps
Thanks for the insight. This will help should I need to repeat the repair on something else. I have ordered the parts and will update the post as soon as I'm confident I have a winner, or if I happen to have any questions after the job is complete....Leave a comment:

Re: 2007 Dell XPS 410/9200 with Bad Caps
Ok great, thank you for all of your help and insight. I really appreciate you hanging in there even with my inexperience and noob nature.
I think I have one more question; can you please tell me why it is you chose this particular capacitor for the job?
I'm thinking 16v because it's rated high enough to avoid over-volting the cap, and with it being an ESR of 8 it's close to, but does not exceed the ESR rating of the original cap? These are a guess, I could be totally wrong....Leave a comment:

Re: 2007 Dell XPS 410/9200 with Bad Caps
So are you suggesting I use either of these as a replacement for both the KZG and the MCZ?
Thanks!...Leave a comment:

Re: 2007 Dell XPS 410/9200 with Bad Caps
Ok, here's what I think I've come up with for aluminum polymer replacement caps for my blown KZG and MCZ electrolytics:
First, specs for the originals
KZG: size 10X25mm, 6.3v, 3,300uF, 0.012 ESR, 2,550 Ripple. Datasheet: [url]https://www.digikey.at/htmldatasheets/production/1172682/0/0/1/kzg-series.html[/url]
MCZ: size 10X20mm, 6.3v, 2,200uF, 11mohms ESR, 2770mA Ripple. Datasheet: [url]https://pdf1.alldatasheet.com/datasheet-pdf/view/144892/RUBYCON/MCZ.html[/url]...Leave a comment:

Failed UCC and Rubycon replacement on a Dell XPS410, equivalent?
Hello, I'm working on an old Dell XPS410 with burst capacitors. I'm trying to source either an equivalent replacement, or a replacement that will work. It's been suggested to me to use Poly caps as a replacement, but I have no idea what to order or what will work.
If anyone has a link to where I can buy what I need that would be even better.
These are the caps that have burst:
Board location: C8BV, C26BV, C43BV
Brand: United Chemi Con
Series: KZG
Size: 10mm dia X 25mm height
Impedance: (ohms max/20c, 100kHz) .012
Ripple: 2800...Last edited by DXseekerMO; 02-04-2022, 05:01 PM. -
Re: 2007 Dell XPS 410/9200 with Bad Caps
So if I am understanding your post properly, when sourcing poly caps the microfarad and ESR specs are critical, and slightly higher voltage rated polys with similar ripple current ratings would be ok?
Should I only replace the burst caps, or will I have to replace all the electrolytics with polys for things to work ok?...Leave a comment:

Re: 2007 Dell XPS 410/9200 with Bad Caps
Thanks for the reply Per Hansson, I saw those caps, and I will be replacing them.
You suggested I "poly mod" this board. I'm not familiar with this mod. I think I read something earlier in this thread about the same thing, but one poster seemed to think this mod could have detrimental effects?
This said, can you elaborate on what the "poly mod" is, and if there could be problems as a result?
My best guess is you are suggesting I use "poly caps" in...Leave a comment:

Re: 2007 Dell XPS 410/9200 with Bad Caps
Holy 11 year old thread revival Batman!
Hello everyone, this is my first time posting in this area of BADCAPS. I normally post in the TV repair forum. I have some experience working on TVs, much of that learned from this site.
Interestingly enough this Dell XP410 PC I'm working on represents a lot of firsts for me.
It came to me in the first abandoned storage unit I've ever purchased.
It's the first PC I've ever "hacked" as it was PIN protected. I was able to get in after...Leave a comment:

Re: Vizio D55-f2 backlight/power supply 20v/24v rail output high 26v
Ok so I found a fuse from a t-con board with the markings "YD". The rating printed on the board was 32V 5A. I removed it from the t-con, installed it on my main board, checked it for continuity after the install and it checked good. I installed the main board, plugged it in, turned the TV on and the fuse blew straightaway. Looks like the Main Board has a problem. Now for where to start?...Leave a comment:

Re: Vizio D55-f2 backlight/power supply 20v/24v rail output high 26v
8 hours run time and the backlights are still on.
I'm still looking to find out if the current rating on the automotive fuse is 3A at 24V. Anyone? And I meant ATC type fuse in my previous post, not AGC type.Leave a comment:

Re: Sharp LC-70UD1U Half screen Normal half screen is white
Usually when we see this we find there are burnt/overheated gate driver ICs on one side of the screen. If by "right" and "left" side you are referring to right and left when looking at the back side of the TV it appears the problem side is upon the right, as in when the right side FFC's are attached and the left side isn't the TV goes in to protection mode and displays the "2-5" error code, but when the left side FFCs are attached a picture appears on that side and the right side...Last edited by DXseekerMO; 01-19-2022, 11:50 AM.Leave a comment:

Re: Can I switch PSUs of same Series ?
The LED Driver IC upon the Main Board has a feedback circuit built into it that monitors the return voltage from the backlight string. If it isn't within a very specific range the IC will shut down the LED driver portion of the Main Board and you will see no voltage.
Try monitoring the voltage on one pair of the LED output at the Power Supply. Unplug the TV, attach the leads of the voltmeter to + and - that are next to one another and while plugging the TV in monitor the voltage. If you see a voltage flash that...Leave a comment:
