Hi to all Members of PSU disign and troubleshooting

My problem is this I recently bought a Cooler Master m1000 PSU
to be exact about 2 years ago until cople of days ago it started to smeell and to
show signs of black fumes comming on bottom of the fan side of PSU
I kinda open my psu to check what is burned but no help i noticed some cxaps burned small ones in the middle but still can\t get a betherlook under the two big heatsinks that blocks nost of the caps I also noticed that two large caps are not damaged and the filtration system is still ok
It wouls make a difrence if some or any of the members have link for schematic for my PSU or knows step by astep how to take those two large heatsinks also there are 4 screws that hold the pcb down i took them out In order to repair my PSU I need to check what else is burned

Please don't put email addresses in your comments, you'll only get spam.
This is an open forum, people should write answers here so other people may find the information in the future if they have the same problem.

Heatsinks in power supplies are not designed to be removed, usually chips are screwed onto to the heatsinks and then heatsink and chip leads are soldered to the board, so you'd have to desolder all the line of leads of the chips and maybe 2-3 leads from heatsink to remove the whole ensemble.

This forum works great if you post some high quality pictures of the board - we may point to you what looks weird or damaged.
