Hello XDA members,
I have been following XDA for almost a decade and now came my time to ask for a help.
I bought few months ago XTRONS D717AL. First of all, great player, awesome radio tuner. Catches many stations I couldn't with my old Audiovox and Clarion. It comes With Adroid 5.1.1 and Intel chip. Model number says: Full AOSP on Sofia. MCU Ver: HY_SFY170224EF.
But since day one I noticed a weird display actions. Radio starts right after I start the car engine, display pops-up and on random basis, sometimes the display lights up, sometimes not. It takes about 20sec to load the OS and apparently, the touch screen is working. I know where the Quick settings are, if I pull the top navigation panel down when the screen is in a working state. There is a Light button, which enlights or darkens the screen.
In a dark state (blank), if a pull the navigation panel down when the screen is dark and press the Screen button, screen enlights. I know approximately where this Light button is and pressing it screen enlights. That makes me think, that the screen darkness goes to value 0 at some point before even the OS load.
I have rear camera and DVR attached, but since I took everything away today except the ISO wiring harness, it makes me think that these AV in signals are not the issue. I even took away the reverse camera control cable, illumination cable, and GPS antenna. Brake In cable is fine attached.
Last week I tried to factory reset the unit – no luck.
Flashed with a firmware from the Xtrons tech support – no luck.
I recorded a video today which I uploaded on youtube (I can't post links yet, too young to do that )
Search "XTRONS D717AL Screen Problem".
If anybody ran into such a problem and a solution, will be much appreciated to share here.
Many thanks.
Edit: I just noticed, that upon switching off the radio, the dark display flashes for a half second on its way going in. Possible display cable issue?

I have never tried to go to recovery of this unit. But, I found another topic here:
https://forum.xda-developers.com/an...button-combination-to-enter-recovery-t3391682
Regarding my problem, I returned the unit and it was replaced with a new one since it is still in warranty period.
Hey everyone,
the last days, the screen of my DE-JY-VM130N2 is turning black. The unit seems to function completely, except the screen. Even touch functionality works. Has anyone ever experienced this?
That maybe some problem on the main board,you can contact Joying support to get after sale support
I guess the problem is the core board soldering off.

Hi, since yesterday I got some issues with my BMW after market screen.
From time to time the screen goes black for 1-2 minutes and come back.
When I'm on the BMW part and click on the screen nothing happen, it does not go back on Android side.
When Waze give me an alert, I have no sound after on all the android side.
Any ideas ?
Thanks.
Hey everyone,
I'm experiencing an odd bootloop on my Joying Sofia unit. It started happening after I hit a small bump in the road- after I hit the bump, the unit went into the reverse camera screen, which is odd because I don't have a reverse camera hooked up; the signal is not connected to anything and was taped up. So I just saw a black screen with the yellow back-up camera lines. It stayed on this screen even after I restarted my car at a stop light. I had somewhere to be, so I turned my car off and left for an hour or so. When I returned, that's when the boot loop behavior began. Most of the time, midway through the splash screen, the unit will reboot- this happens several more times before it gets past the initial splash screen and moves to the animated android loading screen. After this screen, I get to the white "android is starting" box (my unit is running the GTX rom) and then the screen just turns black suddenly. What's odd is that I can still control the screen, and I can see the screen for a split-second as I hit the reset button on the front of the unit. Furthermore, it seems like my USB headers are not getting any power- my 5V fan doesn't spin when connected, and I don't see the read/write lights on my thumb drive when I connect it either.
I've tried to capture the behavior in this video. Any help or guidance is greatly appreciated. I purchased my unit at the start of October in 2017, so I've just passed the two year warranty
