sakurai 580 2017 Abnormal reaction from all ink keys motors !!

[NAGHSHE_BARTAR]

I have a Sakurai 580 UV 2017
suddenly all the ink keys all 5 unit went negative and stuck to the ink fountain rollers and all the valves gave error number 8, that is, the valve gear conflict with the overload

As soon as the ink key motor is connected to the control board, the voltage that enters it can be caused by the disconnection of the

negative voltage in the lines?
If the answer is yes, is it a fault between the units or the color console to the main board?

Hi sir:

Will be a good idea to test the:

1) Main transformer Vac Input for REGULATED Power Supply

2) Output of the regulated Power Supply, in tolerance +24Vdc !!!!!

3) Look for dry+ colder solder joint to the main board+ loose wires+ or edge connector with oxide or corroded ( clean with contacts cleaner very well).
