Re: Suggestion to replace bad caps ?
I don't think anyone has found a datasheet for the Samwha XC caps. Given that, the choices you made look like good low ESR caps.Leave a comment:

Suggestion to replace bad caps ?
Hello.
I´m going to replace bad caps from a Syncmaster 226NW (same as 226BW but only VGA output). Caps are 5 x 820uf 25v (10x20 mm) and 1 x 330uf 25v (?x12 mm).
Is it ok to replace them with these (ESR question involved) :
820uf:

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:

Hello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.
I have studied the board and... -
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."

Hello everyone I have a question. I have a laptop and his schematic. Can anyone tell me how to measure or any way to understand specific of caps so i can buy new one?
Also in case how can I understand if some caps of some dead Mobo i have, are ok to be replaced in my new motherboard which im trying to fix?
Thank you! -
It's feeling like this board has a case of badcaps, instability and reboots - and not wanting to necro a a very old thread, it seems the 680uF 4V are highly suspect.
I don't really want to blanket recap everything, but maybe the others around that area could do with being changed?
Equipment: I have a temperature controlled soldering station, read the bit where it says set to 400F, don't think I would have gone that high without reading that.
Spring plunger solder sucker, and some desolder braid... and a bit of good old leaded 60/40.
PS. Additional diagnostic,...
