Hi,
It sounds like a contrast adjustment is needed, not a replacement of the display. An LCD contrast adjustment usually can drive the characters from invisible to fully darkened blocks. Sounds like yours is close to the "invisible" setting.
I found this which might be a solution to your problem on
this thread on the irv2.com Forums:
You need to adjust your display contrast. It's on the "settings" menu, I believe. To adjust contrast press and hold mode button for 5 seconds. Then highlight contrast adjustment. once highlighted wait 3 or 4 seconds it will take you to contrast adjustments. Once there you press T for "+" or M for "-". To exit go to exit menu or turn ignition off then back on. Hope this helps. I didn't get a chance to try it out on my WH, but I do remember there being a contrast adjustment in the settings, so I think this will hopefully work for you. I believe the ignition has to be "on" for this to work...but maybe not. Try it both ways if needed.
ON EDIT: Perhaps even better, check out this document posted on Oemy's site about the Actia Display:
Oemy's Performance Actia Service Manual pdf . Page 37 has the info I believe you'd be interested in. I noted that my menu looks a bit different than the one shown, but hopefully most of the info is applicable. I did notice these instructions: "On-board diagnostic functions can be initiated and executed with transmission in park, the park
brake is set and the Mode switch is depressed for longer than 5 seconds."
ON EDIT AGAIN: I just went out to test this on my 2004 chassis WH. The ignition has to be in the "Run" position...leveling jack whistle gets to be annoying very quickly! LOL Anyway, follow the instructions on the manual posted above. You have to let go of the "M" key after 5 seconds and the display should show "Contrast". The adjustment, however, only goes from blacking the letter out entirely to still easily readable. It wouldn't lighten the letters too much. So a contrast adjustment might not be the solution. However, there is a "Restore Default" setting for the display which might be worth a shot. There's some neat information available by following the various menus available. I found out the top speed I have hit on my motorhome was 80.3 mph!!! Yikes....must've been when wifey was driving home from Florida a couple of weeks ago! LOL
Good Luck,
~Rick
