2015 California T displays not working

First my center display (the one that shows PSI, Turbo and clock) just wouldn't come on. I touched the sides... nothing. Now my left TFT display (the one that displays mph, fuel level, instrument clusters, etc) is totally black, along with my center display. I had the battery changed 4 or 5 months ago with no issues after... any ideas?? I'm stumped. Thanks to all.

 

May be unrelated … the center (turbo) display can be turned on or off by touching the ring for three seconds. Mine has been randomly off when the car started a few times.

The dead TFT is more troubling. Have you tried disconnecting the battery?

 

Similar to Vic, my center turbo display would turn off by itself without me doing anything to it.
The only way to wake it back up is to go to the menu and turn it back on again.

Just like Vic said, I recommend disconnecting your battery for about 10 minutes. Then reconnect it following the Ferrari procedures and see if that fixes it.

 

I was going to first just let it sit overnight and see if the problem repeats tomorrow (for the left tft screen). I wasn't aware the center display could turn on/off with a 3-second hold, so thank you!

Also, oddly enough, the left display was black for the ride except for when I first turned the car on. The "California" script appeared as it normally does, but after that it just went blank. This was the first time I recall it ever doing this.

Would you do me the favor of articulating the "reconnect according to Ferrari procedures" ? I just thought I'd disconnect the negative terminal, wait 10 minutes and then reconnect it... Is there something else I need to do?

 

Here you go, please see attached.

Hope that helps.
