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 😞.

they are smoothing the low voltage supply to the chip, define a short?
chips sometimes do have a low resistance so unless it's less than say 4 ohms it's not a short.

aaah .. makes sense ..
coming up as 2.6 ohms
I've measured a continuity test from ground to both sides of each cap and across said cap aswell and also when caps have been replaced.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:

input short remove then caps lock 5 long 3 short no output how to solve this problem -
Hey
I got a short on 3 pins of the PCI-E gold connector for 12V.
I see a few caps near the top right (near main power connector) that look blown, one is showing a short across it to GND.
Unforunately I don't have a schematic or board view for it (EVGA GTX 1070 FTW 8GB).
Due to the large number of caps there, I think it may just be decoupling.
Any ideas on figuring out the cap values? There also isn't any reference numbers for the caps on the silkscreen. -
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."

I have a "HP Pavilion x360 - 14-ba104na" in for repair. The caps lock flash 3 long and 5 short.
HP says this error means:
The red light blinks three times, and then five, short white light blinks (3 long red, 5 short white)
This condition indicates that the computer does not detect the processor (CPU).
Does this mean the CPU is dead or is there another cause for this fault?
