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.

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... -
i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...
