Thanks robm, but no luck.
Checked all voltages at test points and all within spec.


Checked all fuses all ok.


Any other tips?

DC at test points is Ok? IC's are seated properly?
Check at test points again but put the DMM to AC and see if you get anything. A digital meter often isn't fast enough to detect ripple on the DC but if set to AC you will see it. If anything shows then rectification is faulty which more often than not down to the electrolytic caps.
