Originally internally coded as LFA, the 2015 Sonata was unveiled in Korea late March 2014, and was unveiled in America at the 2014 New York International Auto Show.

Why is my dashboard LED screen display not working?

2017 Hyundai Sonata: My LED dashboard display, (shows maps, calls, and music) in my car went out one day, but comes on every once in a while when it is below freezing outside. Then after the car heats up a little it will shut off. Im not sure if it is a fuse issue, a screen issue but I have not gotten this fixed for about a year now. I’m not exactly sure how to remedy this issue.

Here is a list of things that might be the cause, I would check them in this order:

1. Hold the reset button (I believe it should be under the volume knob on most newer models for Kia/Hyundai) for 10~ seconds to reset the screen.

2. Check out the below image for the fuse box diagram. I would check the Multi Media fuse (15A) and make sure it hasn't blown. Apparently in some cases just taking the fuse out for 15~ seconds and putting it back in has fixed the issue in some cases.

3. If it isn't the fuse try disconnecting the battery for about 15-20 minutes, but if the fuse didn't work this probably won't either.

If none of this works then you could be dealing with a blown screen or a bad ground.

Hope this helps!
