I have a motherboard with at least one blown capacitor. I found a boardview for the motherboard and installed open boardview hoping that might have the information I'm looking for, but if it does contain the information, I can't figure out how to view it.

Title:
Capacitor detached from PCB – RTX 2070 Super Founders Edition
Description:
During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
I did not notice it detaching, so I am unsure of its original location on the PCB.
Procedure performed:
- Removed backplate
- Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
- Reapplied thermal compound
- Reassembled card
Observed behavior after reassembly:
- GPU powers on and operates normally under... -
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.... -
Hi all, Acer Nitro 5 - GH51M LA-K862P Rev 1A motherboard. I went through all the troubleshooting steps but couldnt find a short on any coils. By chance, ended up finding a blown capacitor PCZ49 which is suppose to be 2.2uF. I can see plenty of 2.2uF in the same +5VALW line which will all parallel up anyway - do you guys think it is critical for this cap to be replaced or i can get away without one?... -
25V 470uF? Any help would be appreciated! This was in an Adam A7X speaker. I replaced with a different uF and voltage closest to the values I thought because it is all I had in stock. It restored the speaker to working condition but it is certainly not what I needed to do as it is putting out less volume than its sister speaker which presumably no issues....

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...
