display screen is dead

Postby sandyL » Wed Mar 01, 2017 1:15 pm

:?: finally got the k4o upgrade installed but may have bad display, the screen is totally dead, no action at all.
I have checked all voltages and can find no reasons for the dead screen. Nothing happens when turned on except blue amp meter shows 0.0. and the axes motors are frozen in place.I really need some advise as where to look or start/

PLEASE HELP

It shouldn't because we tested it before ship
Check if polarity reversed

volt meter reads +24.3 volts
Can you give me a procedure to verify the screen is getting voltage, the module seems to be ok just nothing on the screen and as mentioned both motors are frozen, have wired z table up yet.
