Why This Part Fails Most Often
Common failure modes include backlight degradation, pixel defects or display blackout caused by aging components, faulty solder joints or connector corrosion. Intermittent or total loss of function can also result from power supply faults in the radio/infotainment unit, water ingress behind the dash, or software glitches. Mechanical stress during previous repairs and voltage spikes are additional frequent causes.
