This is the thing which is broken by me. The right cable is cuted.
Is there any option two replace just the cable instead of buying a whole new display assembly?
Thanks for your help and sorry for my bad english.

Thank you! I try it!

Hey,
the cable arrived today. I tried to get it build in but no change. It's too tricky. I think it's not possible to get the screen off without a brick. If someone can put the screen away without bricking it, it's very hard to connect the new cable to the screen.
The phone is dead. Maybe i found a cheap damaged phone with a working screen on ebay... We will see.

I will try it.

Hope you can fix the phone asap

Dasaita 10 PX5 Coreboard not booting

Hi,
I have a 10" 1-DIN Headunit with a PX5 Board from AndroidAutoShop. The headunit doesnt boot, only the buttons on the Touchscreen blinking one time, when power on.
It is 5 months old and AAS isnt replying the mails becaus of warranty.
I bought a Coreboard to check, if the px5 coreboard is the failed part.
In the headunit there is a hct-px5-rev 10(lpddr) and my spare part is a hct-px5-rev 4.0
the rev 4.0 has 4 pins missing. is it compatible or not?

Yes, compatible.

Hello,
I have a Dasaita px5. I have a set of head rest monitors and wanted to know if there are any options on connecting the headrests to the headunit. The manufacturer simply told me to upgrade to px6. I bought this unit 7 months prior to the release of px6, so I'm not trying to upgrade just yet. Any suggestions would be awesome.

You might be best to not hijack a thread that has little relation to your question and post in q&a.

I replace the Coreboard and install Hal9k V4.0.2.
It is working, but there is no Sound from Mediaplayer, Radio, Spotify.
The key sounds are working with the speaker, but no music.
Is there a trick to activate the Sound?

So i thought they shipped a problematic unit, a send it back, bought a new one.... and same probleme, i even thought that it was a problematic flex cable of the motherboard (that i replaced too) , i never find someone who had the same problem as me, on youtube or whatever, it's a big mystery for me and i'm beging you for your help people.
Thank you very much.

Sorry i have no idea how to help you
All i can say is that there is 3 variants of this phone with different displays: Tiamna, another one which i forgot and another one just for really late unit which is known to be incompatible and india exclusive, my theory is that maybe you had the one which is more problematic, maybe, in really don't know i'm just trying to help with the information i have
(btw your english is completly fine)

That's interesting, i saw that a few people are experiencing some issues with tiamna screen but none like mine, i'll look in this path, that's maybe a begining of an anwser.
Does anyone else can help ?

Sygav PX6 RK3399 Android Head Unit blackscreen help!

Just got a PX6 RK3399 Android 10.0 Headunit, when left unplugged from the car for a while of time it will turn on and work correctly, but then goes back to the black screen after a reboot. By black screen, I mean the main display has no picture yet the backlight works. The buttons still make a beep sound but there is no sound otherwise when it's like this. I was able to see the head unit and touch screen still functions by plugging a monitor into the hdmi out on the stereo. I've tried factory resetting and used the RST button to get into recovery mode. The display is still black when in recovery mode.

The chinese support people have just told me a bunch of bull**** like "Have you rebooted the device?" or have I made sure it's plugged in.
Any help would be greatly appriciated. Also depending on if there is no fix. Is this a common issue with the PX6/PX systems? Would it be a bad idea to return it and buy another PX6 just from a different brand?
Another weird thing, it says Android 11 in the settings/about on the device.

Typical poor QA. Send it back/dispute.

Is not common...A Dasaita guy has the same.issue like you.... Could be hardware issue?
Did you make an upgrade of the MCU before getting the black screen?
If no display is very difficult to go to solutions...

Happened to me. I pulled the fuse for a few seconds and reinserted it. The screen came back to life and I haven't had a repeat occurrence in several months

@Tommy141x A couple questions for you, how long have you had this unit? Did you run the brightness at 100% when screen was working?
Considering your post was from March, I presume you've had the unit past the return period. There is a known issue with SYGAV and Dasaita with the TFT board if you run brightness at 100%. I would think that SYGAV would send you a replacement TFT board if you still have this unit and still have problems. I had a similar issue with a Dasaita unit and they sent me a replacement TFT board and that fixed the issue.
