Default Marantz SR5200 immediate shut-off

Hello. Hopefully one of you has some knowledge of this unit. I did find another thread (and many others on the net) about the 5200 but none apply to my problem. I bought the unit new in 2002.

The unit turns on but before engaging it shuts off again. There is nothing connected to the back and I've checked for wire tailings or other shorts. I opened the case and checked for dust/shorts but to no avail.

I'm pretty sure the output stage is fine. It's always been well ventilated and never overworked. Seems to me it's a power supply issue but I'm by no means an expert. So the question is where should I look first? Solder joints? Caps? Overloaded diodes/regulators?

Your help is greatly appreciated.
