Re: ATX CoolMax CX 400B Blown Capacitor
Also, which capacitors are you saying to replace, The 2 large ones ?

Re: ATX CoolMax CX 400B Blown Capacitor
That Silverstone PSU is pretty good for $39.
If it were mine I would replace every electrolytic capacitor in there except the two big ones, even with a brand like CS there. If you wanted to just do basic preventative recapping, replacing the caps on the 12V, the entire 5VSB circuit, and those two 4.7uF 50V caps next to the switchers would probably make this thing last quite a long timeAlso, which capacitors are you saying to replace, The 2 large ones ?Comment

Re: ATX CoolMax CX 400B Blown Capacitor
Just bought this
After the $20 rebate it was only $25

Still going to tear into the old one and see if I can repair it for the sake of fixing it and to have a spare lying around then.Comment

Hello,
I am new to repairing computer electronics, so excuse any mistakes I make.
A friend of mine had a broken graphics card (MSI Radeon RX 5700 XT MECH OC) and gave it to me. It does not power on or show any signs of life.
I identified what looks like the remains of a blown capacitor at the bottom of the board (see picture).
I wanted to replace the capacitor, but I have two questions:- Does this repair have a chance of working? or is a blown capacitor a sign something else is wrong?
- How do I determine the rating/value of this capacitor? or something

Hi everyone,
I'm new to this, so I apologize for not providing enough details. Is there anything else I need to mention? I'm trying to learn more about electronic/board repairs and hopefully fix my own.
The only visible issue on my board is one capacitor, CP813, which appears to be labeled R 221k 2kV (possibly obsolete to B 221k 2kV now). My monitor hadn't shown any prior issues, although it is a few years old. Just before the capacitor popped, there was a high-pitched squeal for 2–3 seconds.
I don't see any other visible damage anywhere else on the board.... -
Machine: Autoclave.
Brand/Model: SANYO MLS-3780
Manual: (Sorry search option not working on this PDF)
Hello guys, this autoclave running with 2 thermistors already connected TH1 and TH3(on CN1,CN2 sockets). One for the water temperture and second one for chamber temperature. But there is another emtpy socket for optional third thermistor CN2 wich is for TH2 for object temperature. I wanna add the third thermistor TH2 to CN2 socket. But i can't figure what model/brand/value i need to use. In manual document, there is no info about TH1 and TH3 model number... -
I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
I know that these capacitor will not last as long as nichicon capacitor... -
I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm
And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...
