Just a quick note to thank both 67firebird455 for the original fix answer and ChevyDriver59 for his post of the video instructions on 01/01/2021. My neighbor had issues with 2nd row monitor while her husband was deployed and asked if I had any recommendations for troubleshooting. I was able to find this thread searching and fixed her problem for a few bucks in cables instead of her having to replace entire module like she was told by dealer...several hundred dollars. Much appreciated!!!
