The MFG and series in question is JackCon LHK. I was wondering what are the preferred brands and series people use around here for this sort of thing. Is FC unsuitable because of the low esr? The circuit in question is the logic board (read: NOT PSU) of a computer LCD that also has HDMI input.

Re: What do you use to replace general purpose caps?
can you use other general purpose caps. afaik rubycon and nichicon make gp caps, im sure all other manufacturers do to. -
Re: What do you use to replace general purpose caps?
hmm... there have been cases of manufactures using GP when it should have been low esr, as a cut corner.
very interesting...sigpic

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:

Recently I was given for free a Sony RCD-W3 with the following symptoms, CD recorder drive reads CDs without any issues (haven't tested recording function yet because I don't intend to burn CDs on that machine) but the reader drive shows disc error after some seconds of it trying to read CD. Tried both CD-Rs and commercial audio CDs with same results.
First thing to do was to clean the lens but that didn't change anything. Googling the issue revealed that this is a common issue on several Sony CD recorder machines and the culprit is SMD electrolytic caps located on the PCB bellow...05-05-2024, 02:04 PM -
Hey guys just wondering as to the purpose of these caps 560 but they seem to be shorted .. is it linked with the super low impedance of the CPU/GPU or do I have a short to search for ??.. the short is still there when caps have been removed.. sorry still learning really 😞. -
I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.
Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.
I decided to verify that the batteries were... -
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...
