Corvette C7 Screen Flickering
I own a 2014 corvette (which is indeed produced by the end of 2013) and as a lot of people, I got this problem of flickering screen.
It flickers then go black, and goes back to normal some times after, then flickers again and so on... Very usefull

Well, the problem is my car is a USA model, imported to Luxembourg. I love it, but my warranty contract does not cover multimedia problems.
I had the idea to contact someone taking care of chevroilet in the United States and give her/him the problem description / vin of my car and maybe get the spare parts that I could change myself. Wouldn't be a problem even if I had to pay for the shipping cost.
Do you maybe know someone working for Chevrolet that could help me?
Thank you in advance and god bless America

I do not have the blue wires, FYI
While my expectations are low, here is what appears to be a fix to this point. Based on all my research there seems to be more than one issue here. Screen flicker or old style TV rolling and blank screen. Mine is the prior.
Started a couple months ago. Researched this as much as I could and it seems the software update was not always a fix and in most cases the replacement of the infotainment screen was the fix. For us out of warranty having the dealer take the dash out is more of an issue than the $895.00.
Took the car to the dealer. The service contact was very interested about the issue but had not dealt with it in the past. Left the car for brake flush and rear axle oil replacement and the Tech was to determine the best route on the screen flicker.
Of course they called and said I needed two software updates. I approved with the comment that I did not think this was the issue.
Picked the car up and the flicker continued the next day. Took a video the service contact and Tech forwarded to GM to get a determination. Came back the screen to be replaced.
In all my reading there was one member that said a horn honk would clear the flicker. My flicker was happening at all times, before startup the floating "V" that turns into the corvette wings would flicker, horn honk would clear. The flicker would happen during a drive and the horn honk would clear.
One member talked about going to the screen, settings, radio and doing a factory reset. I did this. Knocks out all radio settings and your phone pairing. From then on there has been no flicker. Three weeks now. I do understand that some members have had the problem pop up months later and this might happen but I have gone from daily flicker to no flicker for three weeks.
My questions is "did changing the infotainment screen in all the past fixes need to take place? I assume with a new screen you are now at factory settings which might or might not be taking advantage of the new software updates?? Can one just reset the screen as a fix?? Can one just get the software updates and then reset the screen for the fix?? Or does the infotainment screen have to be replaced for a 100% fix.
Time will tell and hopefully this will help someone else that is out of warranty.

Did the factory reset on the radio. Nothing. Talked to the dealership, the car was over a year out of the bumper to bumper warranty. They had discussed issue with GM and said due to the car having so few miles, 13k, GM might offer a prorated fix. Took the car to the dealership. As I waited in line I decided to pair the phone since the factory reset lost the previous pairing. Couldn't figure it out so when the service manager got to me he offered to pair the phone. When he was done I asked if he had seen the flickering of the screen. He had not. Got in the car to see for myself and sure enough it was gone. Decided to leave the car for the diagnostic test. They found that the radio was bad. They could not say if this caused the screen flickering but it was possible. GM offered to pay 65% of the replacement cost of the radio so I took them up on it. It's been several weeks and no problems with the screen.
