So recently my LCD screen in the cluster between the speedometer and tachometer has gone dim. Its hard to make out anything on the screen now. I have a 2013 G37 sedan and this should not be happening already. My car is not really left in hot temperatures long even though it does get pretty hot in south florida. Usually garage kept. When I start the car, the screen shows bright as it should and then after a few seconds it dims down. The brightness it at its max already. I do not know what to do. Some forums say after a few days it should go back to normal but it has been a week now. Does anyone have any thoughts?
