I have a basic 6" bench grinder which I can stop from spinning with very little pressure. When first turned on I can easily spin the wheels backwards with one finger. It basically does not work. I was about to give up on it and I thought I would open it up. Got to reading about capacitors, uf/MFd, voltage and the like. It has a 6uf, 250VAC capacitor. When running my multimeter shows 190VAC. Could the capacitor be the problem? Thanks.

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... -
I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
Frequency: Happened about once a week.
Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve. - Problem: TV shuts down
- Problem: It started with random picture disappearing (sound still worked).

Hi people, I hope this is the correct spot to post this, I'm new to the forum.
I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.
I hope these photos make it clear which component I am referring to:
(yes, the soldering is a bit botched from removing the blown one, I know)
I have found the board schematic (attached), but there does not seem to be a boardview available. I have never... -

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...
