Hi. I have been out to this one and the fault is the machine is totally dead with no display. Have got power to the main board but not sure if this is likely to be faulty or if the power runs through the dryer board before the display. Any ideas much appreciated before I purchase the expensive module to find I should be looking elsewhere.
Main p.c.b i’d reckon is at fault.
Check you have voltage on U3 1&2 which is the power imput connections to board, check on/off selector switch works, also check connections to small p.c.b display.
