Little Monzte

as te' title states, the LCD Screen on my '06 A4 B7 - melts when the vehicle gets hot and I'm wondering if anyone knows of a Cheap way to fix the issue? I don't want to spend 100+ on a new LCD , can I rip one out of a similar vehicle and install it into mine? Just the LCD screen; or does anyone know how I can diagnose where the fault is and re-solder the connection to fix my issue? Any help at all, will be appreciated. thank you. Also when I click "Check" ; it just scrolls thru different icons and says "OK" in the yellow box, is that normal for this vehicle? I have no button to select or scroll so I don't know if I can scroll and choose a setting to see how it's performing- (new to audi' , recently got this one and it's my first one ever- i'm still trying to figure out how to work the A/C and Heater) thanks again.
