Flickering infotainment screen

[Phil Ritter]

The screen flickers and moves around but all the functions work.

I have done the reset, disconnected and re-connected the battery, jumpered the battery terminals and have tried three used screens and a replacement 5F control unit from EBay as well as running the dealer diagnostics.

Sounds like you need a harness...

I think this is the one you need... https://www.aliexpress.com/item/2251832705368978.html?
But match the colors from your cables to the listings in the first link.

You saying simply changing that harness will resolve flickering issue?

Typically flickering or blank screen traces back to a faulty "brains" unit, as the screen is merely a screen

@smittyatl I wouldn't normally say a flickering screen is a harness. I would normally agree with @pedroYUL the main unit is failing. But OP says they've already tried a few used screens and replaced the 5F unit (which to mean means the main unit in the glovebox).

Of course there's no guarantee with anything used. I think the likelihood of 4 screens having the exact same issue is slim. Likelihood of 2 main units having the same issue is 50/50, so it's very possible the eBay unit has the same problem. I would try to source another one.

The cables are cheap though, and good to rule out. I haven't really heard of cables failing but the more you mess with them (in removing/installing parts to troubleshoot) the more chances you have to mess one up.

Flickering screen of death!

So my lcd touch screen, upon starting my car this am, now has the flickering screen... I'm out of warranty, just hit 45k and 38 months of ownership. Has anyone found a solution other than a new head unit unit/screen replacement? This is on my 2015 GSW S model so not a fender unit and no nav...

Have you found a remedy for the flickering screen? Same issue here. Wondering if it’s possible for the cause to be something other than just failure.
