Groovy jellyfish lamp

[mad-elec]

Hi all, my wife bought this jellyfish lamp a few months back and now its just stopped working.

I've already changed the ac adapter but that wasn't the issue so now I'm looking internally.

It doesn't look like a very complicated bunch of circuits, there is where you plug in the power adapter, the main circuit, an attached LED array and a small water pump motor.

I've taken some photos and wondering if anybody can identify parts I might be able to replace that are common failure points?
