Hello all, trying to narrow down the problem spot. 2014 L405 with Meridian system.
Black screen, no sound. Screen will however switch and show camera in reverse or manually trigger front cameras. Touch display buttons illuminated. Visible light @ fiber optic cable on amplifier. Interior fuse box checks out, rear luggage top and bottom fuse box checks out. No visible moisture or corrosive damage.

Anything else I should check or has anyone had a similar issue? Thanks!

I had this when my Amp froze but the screen was lit. Its actually happened twice in the last 4 years I suspect it happens when the battery charge gets low so I usually use the cetek charger every 2-3 months to avoid the "Start Engine now message"

Its not the normal fuse, Try removing Fuse Link FL16 its shown top right of picture

Thanks for the tip, however neither the upper or lower match that junction diagram. Is there another location?

I’ve also used a scan tool to try running some diagnostics, anything radio related whether NAV or amplifier, response is always no communication.

I would start at a battery disconnection...check the battery condition as well.. ... - .- -.
