I have an avic z1 and the other day I was driving then all of a sudden the screen turned white. I then tried pushing some of the buttons on the front panel and none of them worked. Once I turned the car off the white screen was still there. I then disconnected/reconnected the battery and the unit doesn't want to turn on. I hear the fan whining like it wants to go but it won't. I also have three buttons that are lit all the time even when the car is off but don't do anything. I tried hitting the reset button on startup and nothingn Any ideas on the problem and is this something I can fix myself?

This sounds like a professional repair issue on the power board. Sorry.

Any ideas on a cheap service?

$200 flat rate from Pioneer, or check ebay. I have seen repair providers on ebay for specific items and maybe they can help if you contact them.
