Could be the power lead from psu to mpu,try measuring the 12v with a meter to see if it is there

try disconnecting all the outputs from the main board and see if light is there.if light is present reconnect the outputs 1 by 1 and see which one if any is pulling the psu down

The problem is some M1 boards will work in one machine, but not in others.
Where did you get the other ones that you tried? Were they definitely OK or just random untested boards?

The boards where off ebay bought as an untested set of four.
Could anyone provide the order of sequence for both ends of the power lead obviously one end PSU and other end MPU as I took off to clean and not sure of right order
