Video won’t play on front screen even in park. Rear screens work fine. Front screen black even in park. Any ideas why. Did the self diagnose and says tv/rse video input failure and rear video input failure.
How's your battery? Might try a reset. Remove both battery cables and then touch them to each other for a few seconds. Clean and tighten the ends back nice and snug and see what that does. 5 minutes, worth a try.
