Display Help - Pioneer DEH-P8000R

Hello friends,

I have a Pioneer DEH-P8000R from 1999 with the OEL display. Everything works perfectly except for the main display is very dim and can only be seen in the dark. I have gone in and adjusted the brightness all the way to max but it doesn’t help. Unfortunately replacement parts are no longer available.

I am wondering if replacing capacitors or other components on the board may help this issue? The service manual with schematics is available online and linked below if anyone would like to take a look.

Thank you very much!
