Still no response from lemaitre email, no luck with the phone numbers listed on the website. After many nights hunched over the board individually removing components noting their identification on the board & measuring values, I have now reverse engineered the schematic & think I've found the offending resistor. Hopefully makes BigClive proud with his videos giving me the confidence to trace the circuits & produce a schematic from them (that & lack of comms from LeMaitre meant it's do or die for the machine anyhow!) Here's hoping LeMaitre pull through, always been a pleasure in dealing with them.
