GT2560 board not working

[kcunningham92]

Hello

My printer was working great last night, but as I have tried to connect to it today, I have had issues with it. When i go to connect from my computer, a signal light turns on, but I do not have the LCD screen turning on when I switch on the power. I know it is an issue with the GT 2560 board because the power signal light is turned on, and I have tested the powered connection with a multi meter(they each had 12 V from power to ground). I was wondering how I could continue to troubleshoot the board moving forward,

Thanks,

Kevin Cunningham

Hi,you can replug your screen cable and see if your ve vb 5v light is on.

attached is an image of the board when connected to my computer. The green light turns on when connected to the computer. When the printer's source is plugged in, the second image occurs. None of the components appear damaged. The 15 amp fuse does not pass voltage, but replacing it did not solve the issue. There is voltage passing across the 10 amp fuse does.
