It's a buck module, not a linear power supply, you can adjust it without a load.
The VFD is only useful for testing, if you're doing my repair you don't need it you just need to set up the buck module for about 1.5V.

Removing the SMT components is easy. Chisel tip, 30W or more, add a bunch of leaded solder, heat up like crazy (you don't care you're removing everything) and the transistors will slide right off.

As for the VFD socket, I actually soldered the output lead of the buck module to the base of the VFD connector. Not soldering sounded like a potential issue with vibration.

Right hand drive model repaired, thanks to sven337 for the instructions.

Photos of MP1584EN device, testing with DMM to obtain correct output of 1.5v, more photos of the existing transistors and after removal (a few pads came off in the process) , close ups of buck regulator in situ and wiring to pin 1 of VFD connector.

I disconnected the battery negative terminal before removing cluster.
Used a 12v 1.2ah battery from commercial intruder alarm panel as poor mans lab psu for testing.

I noted that there were 5 transistors not 6 for my model.
That ribbon cable is a right PITA to get back in to the slot and close the latch on the connector !

Sorry if the photos are in the incorrect order.

Thanks again sven337 !

Thank you for the excellent pictures that will, no doubt, help people implement the fix.
