Emax

is it the light green screen  pcb i did give a warning on these the tracks bonding material is rubbish and even with the proper equipment you still can get lifted pads

best thing to do with that panel is fit the oled with the other type and hard wire it you can then do surface soldering

i have a spare screen pcb and its the dark green version 

so if you need a spare 

is it a black box type with 2 connections if you look really close there will be in faint red 1k1 on it

were do you live uk or usa or europe 

as i can get the oled displays in white but they have to be hard wired  if ted has no more left

  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.
