It might work only if the voltage across the capacitor was not more than 400v cause the higher voltage will damage the capacitor. However it is easy to tell if the capacitor is damaged by just looking at it's shape that is if you're an expert. But you can use you digital multimeter to test resistance and continuity.



A working capacitor should have infinite resistance to dc current flow, you should see the resistance increasing from a low resistance below 100 ohms to infinite .



A good capacitor should not have continuity between it's leads, but please note that when testing a discharged capacitor you should see the resistance increasing from a hundred ohms to infinite on your digital multimeter.

Yes

The capacitor should not have been damaged.

It might work.

While trying to measure voltage from a capacitor I didn't properly read the intructions and connected both ends of a giant filter capacitor (it 's for 180Uf, 400V) to the multimeter...while the whole curcuit board (from the monitor) was plugged in. So there was a huge spark and it shorted out. That caused the fuse to blow and now there are dark areas on the board at both pins , but the capacitor itself looks okay. Is it possible it can still work? I can't tell yet because the monitor wouldn't power on even before this accident but now im not sure if I should replace the capacitor too...
