Are Panny FM series good enough for a Delta (Dell) PSU?
Or do i need better caps?

Re: Dell PSU recap. Which Caps?
Yeah, they should work just fine but you might want to check the data sheets of the (most likely) Ltec caps you are replacing in the PSU. My favorite are United Chemi-Con KY series caps, ever since one of the members recommended them to me I've been using them for almost all of my PSU's recaps. -
Re: Dell PSU recap. Which Caps?
The origionals are OST RLP and Ltec LZP.
So the Panny FM's should be OK for PSU use also could i use these for the other ones which i can't get in panny fm's? http://uk.farnell.com/jsp/search/pro...sp?sku=1144684Comment

Re: Dell PSU recap. Which Caps?
Yes, I think mixing ZL and FM is fine... They're pretty similar in spec.
If you're going to go through the trouble of re-capping the PSU, you should do a total re-cap. If you posted pics and a detailed list, someone can find you the best caps to use.Comment

Re: Dell PSU recap. Which Caps?
I did recap it a while back but only used really cheap caps off ebay. I didn't know what i was doing. (Didn't make any diffrence)
I will try and get some pictures up tommorow.
Should i also replace the really small caps like <80uf?
ThanksComment

Re: Dell PSU recap. Which Caps?
Yes, absolutely. The daughterboards with PWM and 5VSB chip should also have some small caps that should be replaced. If you use wick on the pins, you can lift out the board so it can be worked on.
What exactly are the symptoms with this PSU? How do you know caps are the problem?Comment

My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

when i press the power, fan goes full speed, power button lights up , and caps lock light is on, the screen polarises, goes dark,no backlight...All voltages present, except PL4701, but that's probably for GPU power later....
I've tried a few dumps from posts, it always acts the same, so i thin it's not a bios issue...
No shorts found on the board...
What should i try next? -
Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
