Dead pixel failure repairs on Audi dashboard instrument cluster LCD display
Audi A4 and A8 dashboard instrument clusters (OLD VERSION PRODUCED BEFORE 1996) may have the common dead / fading / disappearing pixels on the LCD display that shows the time, radio, and the on board computer messages and other functions. Whereas at newer models the problem lies with the LCD display, at older versions the pixel problem lies with the ribbon cable / flat cable that connects the LCD display to the circuit board of the instrument cluster. The pictures below show the instrument cluster’s LCD display before and after the LCD display / ribbon flat cable replacement.
