I have a refurbed pioneer avic-z1. everything went fine on the install, but I noticed the touchscreen was very off on the buttons and when I parked and went to a store for a few minutes, I came back, turned it on, and the screen was completely blank. The music still plays, the buttons are lit up, and the touch screen even works if you guess where everything is located.. Is there any fix for the screen not showing anything or should I send it back?

Have the same problem.

Did a hard reset but still no screen.

I think my screen is the problem.

Taking it to my installer

There could be also a problem with the ribbon cable running from the unit to the back of the screen. Its very fragile.
