Emax

Thanks for the help, but I can't find it.  There is something right from pin 2 that is unlabeled and has no continuity, but I'm not sure if it's a fuse.  


Anyway, even so, I unsoldered the display to be able to look for the fuse.  I decided to just put the old display in and while soldering noticed nearly all the pads were lifted.  I tried to hook it up anyway, just to see if I could get it to work and I just get one row of black boxes with a line through it and a lit enter LED.  


I know I can jump all the display lines and fix that, but I don't know if there's a bigger problem, which judging from the way my day is going, I'm almost certain of it.

I checked continuity on the old display that's in there, every pin is connected, but when I power up the emax I get a blank screen with black boxes on the top.  Seems like I just turned it into a paper weight.

they are usually 1k1 written on them they are flat squares 

if you look closely they will have fuse1 written in very small writing

pin 2 on the display will go to the fuse first so follow the track for pin 2

Power supply is putting out the right voltage. It could have been the 5v. How can I find out which is the fuse on the display? Nothing is labeled as a fuse.
