Hi there
Your last statement about a power cut, may attribute to the cause of the problem. When the power comes on after a powercut, you may get an initial surge of electricity. As you have checked fuses etc, the data projector may have been fried. Sometimes you can smell it on the burnt out device too.
One thing to do, is try it in a different power outlet, incase the power outlet is faulty, or flick the reset switch on a surge protector (if you have one). Are there any lights comeing on at all? Short of that, the data projector may need to be repaired or replaced. I would contact and Authorised Sony Repair Centre, to see if they can do anything.
Hope that helps.
