Emax

only if its an led display warning the led display is 7mm thicker than stock item which means having to cut the front cover for the display to set through it then sits level with the front panel i glued a glass lcd cover plate to the front of the panel to protect the lcd

but if its an el foil backlight version then the inverter needs to stay

the pin 3 connection from the pcb needs to be cut and the pot needs to go from theov and the 5v pin and the wiper need to go to pin 3 max voltage is 4.3 volts this is full contrast

the old lcd used negitive feedback for angle view as the new 1,s use positive voltage 

ted has also replaced a lcd screen i think he used the el foil version

  Subject: [emax] LCD replacement from RS


    
  This company has changed their website to accommodate foreign buyers and
  in the process it seems it has discontinued the
  PC1602AR-H
  <http://export.rsdelivers.com/product/powertip/pc1602ar-h/alphanumeric-l\
  cd-display-pc1602ar-h-16x2/2143244.aspx> (stock# 214-3244) and
  replaced it with PC1602ARS-H
  <http://export.rsdelivers.com/product/powertip/pc1602ars-h/alphanumeric-\
  lcddisplay-pc1602ars-h-16x2/2143301.aspx> (stock# 214-3301). Are these
  the same thing?

  Also, when i do the replacement and solder on the required potentiometer
  to the display, I just have to remove the inverter box on the main board
  and that's it? This will cancel the the high frequency hum also?
