PPC4 and PPC4E/PPC4EX Advanced UI Display Replacement

The displays for PPC4 and PPC4E/PPC4EX with the advanced UI have changed from having an LCD with a fluorescent backlight to one with an LED backlight.  The image below shows the advanced and basic UI's (displays) for clarification. The information in this article does not apply to the basic UI on the right:

  

 

For PPC4's with serial number 1343 and below you will need all the following parts for the conversion. It is possible to modify the metal bracket if want to take on this task on your own:

PN:                         Desc:
4290434                New LED backlight type Display
3367182                Mount Plate/Bracket (it’s possible to modify/notch the original if desired)
4625968                Power cable
4467574                Gasket

For PPC4's with serial number 1343 and above you will only need the display.  For PPC4E / EX models it is unknown if the LED backlight power cable is required.  You will need to inspect the rear panel for a 3-wire cable (2 red, 1 black wire), and if present then you will not need to order one.

Below is an assembly diagram to help visualize the display replacement:

This image shows the inverter box for the old fluorescent backlight.  The new LED backlight will not require the inverter box and it can be removed. 

 

If you have an old inverter mount plate then it will need to be modified by adding a notch to the right hand side.  The notch will give access to the LED backlight power supply:

The cable connects to the main CPU board:
