Monitor On-light flashed only for 0.1 sec when tried to turn on.
Next day turned on and worked fine.
But only for a day, didn't work any more after that.

Opened it up and see a swollen capacitor.
Would that behaviour be the Capacitors fault or something else?

There's a lot of this about. I suspect caused by heat inside a small space.

If you can solder*, replace all the capacitors of that voltage and value with ones of the same value (slightly higher voltage not a bad thing). If you're not sure about values take a sample damaged capacitor with you to the electronics hobby shop.

When removing and replacing, note polarity (usually indicated on the circuit board and on the component).

Capacitors are cheap -- and if you already have a soldering iron the only additional expenditure I'd recommend is a small solder pump which makes it easier to remove stuff without damaging the circuit board.

*If you have to take it in to a repair guy it still shouldn't cost much as it takes anyone experienced under half an hour to do the job and the parts cost very little.
