Greetings all,

 

I purchased a used car "Audi A4 2005" with the Pioneer avic z110 bt. The original owner said the screen started to cut in and out also he spilt soda on the unit. Attached is an image of the screen at startup. It goes blank after a few seconds. The eject button work however, I can not enable the test function either. 

 

I downloaded the service manual and checked all the power test points and fuses which were all good. If the CC unit is removed, the fan spins on startup and I can see the display boot with the funny lines as expected. 

 

A month ago I purchased the same unit on ebay that was used. This unit power on and ran great for about another month. Then I started getting the same screen image on boot up as the previous unit did. It would reboot and things would work again. After another week the unit stayed stuck in the same condition as the 1st unit did.

 

Before the 2nd unit failed, I updated the firmware to version 2013. Can't remember what the exact version is but it fixed the bluetooth and Pandora worked.

 

Is there something I missed?

 

Is this a common issue with these units?

 

Perhaps a bad batch in production?
