S900 just didn't boot up today? Help!

Hi guys,
I have a S900 I have been using for a few years.
I turned it on today and it was dead. The floppy drive has power but no lcd light or status led's above the menu buttons. Anyone got any ideas as to what could be the issue?

If I can work this out I would be extremely grateful

Faulty power supply?

Dried out capacitors?

Cold solder joints?

Other component failure?

You got the machine in front of you, all we can possibly do is guess.
