Hello all,
I just recently had a fan short out and it immediately shut down my machine. I checked the power supply and its still outputting 24v. the board its self has a red LED still on. Power switch lights up, but there appears to be no power to the LCD screen. My first thought was something on the small power distribution board that the fans plug into (on the hot end gantry), but i have that unplugged with no change to the LCD.
Is there something on the board or the LCD board i can test to figure this out? thanks

Re: LCD Screen issue
Hi,
I have the same problem. I was trying to replace the extruder on mine and I guess somehow I caused a short. Now the power light comes on but the screen won't turn on. I think the board is shorted out and might need to be replaced. Could be whats happening with you. Try this. with the power off. move the bed back and forth and see if the screen lights up. If it does then it's probably the board that blew a fuse.

You can check the fuse, the main board has two power supplies , one for the power and another for the electronics
check this schematic (on the left you can see the fuse):
