My Iiyama has just stopped working

cozumel

Its a Prolite E481S like this

Basically had a problem the last few days with it not powering up when booting cold and now it just sits there with the blue light flashing on and off. No noise or anything. So I've switched to an analogue monitor (with a dead pixel) which is highly unsatisfactory.

I've never really taken a proper look inside a monitor before. Is there any common fault that I could check and is easily repairable.

Thanks

Edit: Just looked at IIyama website and its got 3 year on site warranty....yeahhh!!! It's about 2.5 years old!!! Yeahhh!!! Just gotta find the receipt now. Boooohhhh!!!!!
