Thanks , George .

I really thought that finally I was going to get it nailed . The problem was annoyingly intermittent and completely ruined movies and more particularly music listening sessions .

I was , quite literally , like a kid at Christmas when I got the package opened ( especially as there were a few mishaps with getting getting it actually delivered beforehand ). Just powered down and removed the screws , missing on the replacement , from the old one carefully taking photos as we went . There are basically 3 plugs to be connected and the VGA - like connector .

All were attached correctly and yet at power-up we were greeted by a very angry lawnmower - like sound ! V. scary !

I suppose if I were to reinstall the original board and it worked it would confirm that the replacement is , in fact , somehow damaged ? Apart from a slight bend in the frame at one end it does not look damaged .


Robert ,

The board came from M . Original problem thread here :
