AVR 300 Powers up, 8 seconds, powers off

My AVR 300 is 4 years old and has developed a problem.

It will power up and begin it's self check, then shuts off.

I opened it up, and there is a large capacitor (3300Uf) on
what looks like the Digital Analog board (the big board that
lays flat along the bottom of the chassis under the add-on
cards, which is bulging. It also has a darkening of the
board under that capacitor like it has been heating and cooling there.

I can't see any other caps that are bulging, including the
4400uf.
The diodes around that cap are larger than the others on
that board.

Someone mentioned that they had a PDF file for this model, which was a schematic?

It was expressly for finding the problem diodes. But Id
be curious if anyone has any thoughts on this

Just to share my experience with CONDOR AUDIO in Israel. 
My ARCAM AVR350 was turning off after a few seconds. I contacted different companies in the US with no success. FYI I live in Florida. I found CondorAudio on internet, sent an email and the answer from Menahem showed me that this guy knows his field. I gave me a fair price for the repair and all the instructions  to remove the cards involved. Few days after I sent the package he contacted me to let me know he was done. He sent me back the cards with complete instructions to install it back.
Turn on my Arcam and it works perfectly. Not only Menahem fixed the problem but he improved the quality of my ARCAM.
This guy is an expert, no doubt! I recommend him for sure.
