2008 S80 Display Unit
 

The display unit in my 2008 S80 doesn't function and hasn't for several years. However, an odd occurrence last summer prompted me to consider that there might be an easy solution to restoring it to full performance without spending money to replace it. I live in a hot and humid climate. Last summer during one of those unbearably hot days, I parked the car with windows closed for approximately two hours. When I returned, I started the car and engaged the AC as usual. As I waited for the AC to deliver me from the intense heat, my mind must have wandered to next task on my list. Suddenly, I realized that the radio was playing and the display screen was looking back at me!! I was so happy!! I drove home (a short distance) with the knowledge that my precious car was whole again. The next morning when I started the car again (heat had not built up in the car), the display area and the radio functioned for a short time, but then it stopped and has not worked since that time. Any ideas or suggestions would be greatly appreciated.

Harline fracture on a circuit board that closed from expansion due to the high heat. When it became cold the fracture opened again.

Thank you. Is there an easy fix? I would like to trade in the car. That malfunction will probably greatly reduce the value, but I don't want to invest any more money.

Unfortunately, if that is the exact problem, no.
