Nav Backlight problem

[EricP]

I have a problem with the navigation screen on my i3.
At first it flickered sometimes - darker, brighter, and then stopped at the normal bright screen.

Recently, the screen remains unlit all the time, or poorly illuminated, dimmed, when starting it lights up normally for a while and then goes out again.
You can see the graphics, but there is no backlight.
It looks as if the backlight of the screen itself has been dimmed to a minimum with the knob.
Instrument screen and other lights are ok.

I checked the plug on the radio under the sofa and those to the screen - nothing has changed.

Anyone have any ideas/similar experiences?

Hello EricP –

What year is your i3?

Hello EricP – geometry dash scratch

What year is your i3?

I have the same issue and my i3 in 2017

My i3 is 2014 REx.
It was fine for some time, it didn't blink, now it happened again...
I don't know what could be the cause .
I have 3 ideas :
1. problem with the cable ( maybe someone knows part number the cable for this 10.25" screen )
2. The problem is in the screen itself (cold solder joints on the backlight, cracks, anything else ).
3. External problem ( regulation error, light sensors - but other illuminated elements work and can be adjusted with the knob )
4. any other tips ?

If I had to guess, both of you can Roadtop carplay interface or something similar installed. Am I right?

No, i have just regular system, wihtout any interfaces.
After few weeks of darkness it "repairs" itself, and now is normal screen with backlight.
