How to repair power supply adapter D-Link 5V 2A JTA0302D-E

Greetings, I want to share my knowledge on how to repair a power supply adapter for D-Link access point.
The first news is not very pleasant one, the only unpleasant news - the power supply adapter cannot be taken apart (non-collapsible)! That's why it's necessary to carefully squeeze the block on the sides, so that the glued seam would crack open. Personally I put it on the floor, put a knife to the seam and gently hit it with a hammer.
The principle is simple, look for swollen capacitor, and change it. But there is a nasty 20V zener diode, it gets very hot and dries the capacitor located next to it, obviously, this capacitor is also to be changed. On external examination it didn't attract my attention, not swollen, no leaked residue, but as it turned out it dried.
Here is a list of things I had to change in all of the power supply adapter:
- 22 mkF 400V - in the picture it's the biggest
- 1000 mkF 10V - this one and the next one are usually swollen, to unsolder them was a nightmare, they were glued solid.
- 220 mkF 10V
- This sweet couple was actually the troublemaker - 47 mkF 25V and 20V zener diode.
Thank you for reading, good luck!
Just in case here's the schematic:
