When I turn it on, the power light goes on for a second or 2 as normal, then this noise starts and the power light flickers in sync... (no image on screen... not even illuminated blank)
Any ideas what it could be?
Well it sounds a hell of tha lot like a tripping breaker. Beyond that, I have not a clue. I would suggest a flexable TV repair shop, and be prepared to be shocked by the cost. Or as suggested look for an "new" one. In any case invest in that scan doubler. they are life savers.
