Jenn Air Wall Oven Dim LCD

[asuwish824]

I recently purchased a Jenn Air Wall Oven model number jjs2730ws00. It functions properly except that the lcd display is rather dim. No adjustment in the settings seems to improve or even change the dimming/brightness of the display. My hope is I can repair the current display instead of purchasing a new or used unit to replace. I prefer to fix at the lowest point for the joy of the repair. Also throwing out what would otherwise be a perfectly good part just because perhaps a capacitor or other small part is bad seems obviously wasteful. Any guidance would be appreciated.

PS It should be stated that a visual inspection of the part has not taken place yet, but should be done by the weekend.
