Hello,

 

HP 40040dn printer, has a black display. It is offline on the network. I replaced the formatter in the printer but the screen is still black. I still changed: LVPOWER SUPPLY PCA ASSY 220-240V. And I also replaced the display. But the problem still persists. please give me advice.

 

Thanks Pavel
