Power Supply Repair (EAY64509202, LGP27-16PIT)

[KejuBartin]

Hello everyone,
I was sitting in front of my computer when suddenly my monitor (LG 49WL95C-W) turned off. I opened it and started troubleshooting. It looks like the power supply is the problem because if you connect it to power, the fuse blows immediately.
I live in Germany and therefore the power supply receives 230V AC RMS. It outputs 20V DC. I started doing some measurements and analyzing the circuit and the power supply has a short circuit after the capacitor on the DC side.
Two names to find the Power supply in the internet: EAY64509202, LGP27-16PIT
Now I don't know how to continue finding the problem. Does anyone have any ideas what the problem could be? Or any help/advise in general? Feel free to ask any questions.
(I am a beginner in electronics and have tools like a digital multimeter, lab bench power supply and an oscilloscope.)
Images of the PCB are provided below. I took two pictures of one side of the board to be able to read text better.
Many thanks in advance,
Keju

Edit: better text formatting, added part numbers.

By "after the capacitor on the DC side" do you mean:
1. C611?
2. Does it read short at C611, or only somewhat after C611 and any circuits between that and the DC side?

It could be C611 or some switching transistor on that rail. Remove and check C611, and measure the resistance of the circuit with C611 removed.

As you can see by the arrow in the picture below, its this capacitor (C611). It's positive terminal is connected to "CAP +" that I wrote onto the PCB through the fuse that always blows immediately on power up. From that point after the fuse it's shorted to the negative terminal of the capacitor.

I posted a replay and them removed it because I didn't realize there were two fuses    Tomorokoshi is problably right, check the switching transistors or the bulk cap.
