What could be the issue with the rear entertainment system in my 2019 Honda Odyssey that is causing it to not function properly?

One of the main reasons why the rear entertainment system of your 2019 Honda Odyssey may not be functioning is if the power for the rear display is turned off. To rectify this issue, access the Rear Entertainment app on the display console and look for the power button located at the lower left corner of the screen, indicated by a red circle labeled Rear. Press this button to turn on the power; the circle will then turn green, and the system should start working. If this solution doesn't work, there might be a hardware problem causing the infotainment system to crash and become unresponsive. This is a known issue with the 2018 and 2019 models that can impact various features such as the navigation system, audio, camera, Bluetooth, and both the cabin and rear entertainment systems. If the hardware failure is indeed the cause, you may be eligible to participate in a class-action lawsuit and receive compensation.
