These are the components that were faulty. The big chips are HCNR200 high linearity opto couplers, the LED's were open circuit, happened during the repair, part of my own creation :(

 

The other chips are CMOS 74HC4051 and 74HC4053 which form part of the ADC.

 

The three 8-pin chips are op-amps and note the two open circuit resistors....!
