My 2014 Lexus LX570 have a drained battery last week due we left the interior light on. After we jump start it, I find that my navigation screen was black with no response. I have searched and can't seem to find anything in the LX forum regards to it.
I tried the below from the IS forum where the person have similar incident with his 2014 Lexus IS 250. It didn't work for me. I'm planning to bring it in to my usual mechanic shop to have them diagnosis it but want to share this here.
Here is how to reboot the navigation/display screen:
1. Remove the battery terminals for positive and negative
2. Leave the battery unplugged for 30 minutes to an hour (may actually require less time but this is how long we waited)
3. Press the Start button once to turn on the accessory/battery mode (DO NOT HAVE YOUR FOOT ON THE BRAKE AND START THE CAR). *If you start the car the screen will still remain black and you will have to start over
4. Press the PWR/VOL button to turn on the Radio
5. The display screen will light up and show a progress bar showing it is loading the information from the SIM card. Once this completes the system will reboot and the display will light up as normal.
