right, If I press power again it'll have sound for about 5 seconds but the screen won't power up and red flashing continues.

Steven :

Ok this is an old style CRT projection with High Voltage and 3 Pictures tubes, usually the led flashes a certain number of times then pauses then reflashes to give us clue as to what is going on, with out a fault cade it's going to be hard, are you going to try and trouble shoot your self? what type of information are looking for?
