Hello,

Couple of days ago I just started my car and noticed that the screen remaind black, with no signs on power. I thought that my screen went bad but the rear camera video signal works just fine. Then I noticed that the radio unit didnt turn on, like it wasnt receiving any power, there was no reaction on radio button press. On my way to work the display just came on suddenly, and music started to play. I thought OK maybe there was some weird issue, but then the same exact problem reoccured same day. Today I took apart the interior to gain acces to the radio unit connections form behind. I tested the Constant and ACC power inputs with a multimeter to ensure the unit receives 12v power and it did. Then I assembled everything back and turned the car on. To my happiness the radio unit turned on and I saw an output on the screen. Later that day the monitor stated to flicker intesinvely but I can still hear music every time I turn on my car. What can be the issue? Is the radio unit went bad? Can this be repaired?

Attached you can find two videos, first showing that the unit was working fine after I assembled everything back in and the second one is later that day, when the monitor started to flicker

 

To anyone having similar issue, take out your head unit and find a relevant repair technician, mine went bad due to malfunction in the circuit board which was resolved within hours and that costed me around $65 (im not a specialist I cannot say what was bad about it), now the head unit works just fine.

 

Can you share the technician or shop that you used?
