I have a 2011 base model Silverado with 4.8 V8, Single cd player stereo. Recently my display will simply go blank on the driver's side while the passenger side seems normal. I can tap on or around the face and the dead side will occasionally come back to life. My truck just turned 60,000 miles and is in great shape. Since I basically listen to news or talk shows I don't have any interest in replacing the radio itself. Is this a known issue and is there a known (and hopefully easy/cheap) remedy. I appreciate any help.
