I’ve gotten the dreaded “Black Screen of Death” and have gotten up the courage to attack the problem myself. I’ve studied the YouTube videos on how to disassemble the dashboard and remove the disabled screen/unit. My question to those of you out there that have gone the do-it-yourself route rather than the Stealership……Do you know of a reputable repair service that I can send the unit to for repairs? I’ve got two dacades of teaching Automotive Repair so the dash disassembly doesn’t scare me but I draw the line on electronics, no proper test equipment and knowledge. I’ve seen the repair threads on the Forum but unless the problem is obvious and external I’m not going to try to repair it. I can’t see buying a used unit from a dismantler (problems waiting to happen) and haven’t even priced ($$$) a new unit from GM, if they’re still available. So, anybody out there that’s gone the route that I’m planning and had a good experience with an instrument/electronics repair service? Thanks in advance for your advice and help!

 

We haven't had the problem yet on our 2017, but would be interested in seeing what you discover about price for a replacement unit: new GM vs used vs repair.

Mine would flicker like an old TV set, then go dark. Then the next time I'd drive it, for no reason it would start working properly. But eventually it would flicker and go dark again. But the touch controls on the dark screen always worked when I punched around on it, even when it was dark. Very perplexing, but it wound up being a simple repair..

When I got to the infotainment screen on my C7, I found the wires and everything to be in good condition: no frayed wires, no signs of a faulty solder on the circuit board, etc. Eventually, I found that when I wiggled the male end of the blue wire that connects the circuit board, it didn't seat quite properly in the female connection. A teeny, teeny bit of wiggle, but just enough I thought it might be the problem since I couldn't find another obvious issue.

So I wedged a little piece of foam behind the wire, right at the connection where the male end goes into the female connector to wedge it tightly, zipped-tied the wires, and buttoned things up hoping for the best. Sure enough, my problem has been solved. It's been several months and the screen works great with no issues, even on bumpy roads or during aggressive driving.

Another thing, just for information: The blue wires do not actually plug into the screen itself. There is a detachable circuit board behind the screen that is connected to the screen by a ribbon wire. The blue wire that was loose on mine actually plugs into the circuit board attached to the back of the screen. (I'm curious if GM sells the circuit board separately.)

Happy Motoring!

 

Seems to be a problem mainly with 2014s and some 2015s. Multiple reports of the infotainment screen flickering or going blank—often tied to wiring damages due to the retractable screen mechanism.

 

Did GM change something in 2016?

 

maybe the guy that was pushing that cable.

 

I recall reading something a few years ago that the two blue wires were somehow bound together or otherwise reinforced to prevent chafing, etc. Can't recall a specific year that was mentioned.

 

I believe the constant opening and closing of the screen contributes to the problem of working the connections loose. So to play it safe, I've stopped accessing the hidden compartment behind the screen and it's been several years now and not a single problem with the display. Keeping my fingers crossed.

 

Models from 2016–2019 had improved wiring connections compared to the 2014-2015 models. Chevrolet reportedly updated the HMI module after 2015 to address loose connections.
