I have a Corolla Altis 2016 model with the infotainment system shown in the images below. It has been working fine since I bought it but now it has suddenly gone blank. When I start the car the Toyota logo shows up and if I change the gear to reverse the rear view camera also works. But once the logo goes away the screen stays blank. I can touch the screen and all actions are being performed, I just can't see anything. Once the screen is blank the reverse camera also doesn't show up.
I have tried disconnecting the battery and resetting the system using the reset button above the mute button but it still isn't working. Any ideas what might the issue be?
