Just powered it up on the bench and started to trace the blanking signal. Got half way through tracing it and it had the wrong polarity because the blanking LED had gone out and the diagnostic LED started flashing. Put it back in machine, worked for two minutes then back to dead.Back on bench, 30 seconds later working again!!! It's now back in the machine and appears to be working fine but I suspect there is a faulty connection somewhere. Time will tell.
