That's a coincidence tugman, so have I, same model and everything.  Mine has been at the repair shop for 3 ruddy weeks> Keep phoning them. Same symptoms as yours, Got a blue screen for a split second then black out and zippo!  Repair man says "its the Power Board" , he  has tried searching for spares. So far I have heard nothing back.  It can't be more than 5 years old. Problem is that Curry's no longer have a repair service and Logik was their brand name, label or whatever.  If I had known that I wouldn't have bought it. If I get any further with this i.e. the repair man comes up with the spare. I will post message again
