My work throws away (pays to recycle) our broken obsolete electronics. I grabbed a couple of NEC monitors and decided I would see if I could fix them. They all show bad caps. I replaced the caps on two and they work great and gave them out at work so they could use dual monitors. Anyway I opened another NEC (rebranded Benq) and noticed the following 3 caps. The two on the left are 1000uF but the silver only says 1000 16v. I assumed this was 1000F but I wanted to get your opinion since I don't want to put the wrong type in. Here is a pic of the caps with an insert of the same type of cap elsewhere on the board. Sorry if pic is too large.

Re: is this 1000F or 1000uF (pic)
It is 1000uF... 1000pF do not need such a big size body. -

Is that silver cap a Nichicon HD? They are pretty good.... I don't know why that one is leaking....Don't find love, let love find you. That's why its called falling in love, because you don't force yourself to fall, you just fall. - AnonymousComment

Thanks for the replies. All of the pics I found of actual Nichicon HD's had "Nichicon" where this has an oval.Comment

That Nichicon HD will be fine, but you can use a larger can-size cap with higher voltage if you have the space, maybe a Panasonic FC 1000/25v instead. There's also a fair chance that every Lelon on the board will also fail eventually, so you might as well replace them now.Comment

Thanks I replaced all 3 and now the monitor works. I don't have enough caps to replace all of them but I will order them Monday. Looks like someone will be getting dual monitors at work in about a week.
This one was a NEC Multisync 1720M (Made by Benq)

they can have an oval. i have never figured that one out though, nichicon appear to only use the oval on the HD series?All of the pics I found of actual Nichicon HD's had "Nichicon" where this has an oval.Comment

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,
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!
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... -
I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,... -
Good evening
I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?
But I was also suprised about the bigger boys, which are 330µF 25V.
Could it be they used 25V caps because they were cheaper / available at that time?...
