Hi guys,
I just bought a car unit android 8, but the screen sometimes (90% of times) looks flipped left-to-right. Sometimes is also flipped upsdide-down+left-to-right.
And sometimes I get the screen working as it should be, flawlessly, until I do not restart the car.
The defect appears from the beginning, right from the initial logo, and it remains also if I try to reset the unit. Also when I get the "boot" text menu, it appears flipped as everything. (edit - in addition, the touch layer still working in the right way, so I cannot easily understand what I'm touching on the screen, and this makes everything more complicate)
The unit is a px5, 4GB RAM, 8-core, the MCU is MTCE_XRC_V2.93_1.
I didn't already tried to overwrite the android files, because I'm trying to get some assistance from the producer. Anyway the product is coming from China, so I guess I will have to do it by myself. Until now, I rebooted, reset, cleaned, changed startup settings, and spent a lot of time in doing and re-doing all these tasks, but the unit still like at the beginning.
My question for you: do you think is it hardware problem, or can be fixed with a firmware update?
Do you have any suggestion, setting or trick in order to solve the problem?
Thank you in advance for your help.
Kind regards
It looks like a hardware problem indeed. The touchscreen 'digitizer' is apart from the display in the front. You could try if the ribbon cable inside the radio is firmly connected to the mainboard i guess. Otherwise i think a new screen..?
I will have the same issue with this same units. I write to selller , he send me a new spare part responsible for displaying the image.
I have the same problem. What is the spare part that solve this probem? Thank you in advance.

Recently I began to notice a problem with my phone. Whenever I have the keyboard slid out the touch screen is almost non-responsive. So over the past few days I've tried observing what the exact problem is and I think it could be the cable/ribbon that connects the touch screen to the keyboard. I'll have to tilt the screen back and forth before it will actually recognize me touching it. And I've noticed when I rub that ribbon it seems to work. There's also a crease in the ribbon where it folds on it when you close it. I believe this is the problem but I'm not sure and I want any advice/tips I can get. If it is the cable can you order a new one and replace it yourself?
Thanks in advance
Any ideas anyone? I cant get it to half work so I can text and stuff but I have to press it hard and it still wont work at times so something somewhere or another is wrong.

Flash the stock ROM and SPL, and do a warranty exchange. This isn't a device you want to open up unless you really know what you're doing and are certain of the issue. If you really want to give it a go, then just buy a non-functioning unit from eBay to use for parts. They can normally be had for less than $40.
Wow, I cant believe that I finally found someone with the same problem as I have.
At first I thought that it was a software issue and I reloaded the software on my device.
The screen responds to presses with the keyboard in, but extended it doesnt respond and only the external keyboard works.
So to type a nice long sms I would have to start it on my display, flick out the keyboard to carry on and then flick it back in before I could press send or anything.
How frustrating.
But I did a test now and flicking the keyboard out and then slowly slowly pushing it back in I can get to a stage where both the external keyboard and screen responds at the same time again.
Definitely a ribbon problem or something.
Only had this phone for a few months now and if it already doing this then I am not feeling too obtimistic about its future.
Well, time to take it in for a warranty repair. I wonder how much greaf I am in for now.
Time to pull out my awesome trusty Artemis out the cuboard.

I had a friend that had this problem with his TP2 which I've successfully repaired. First thing if you want to do it yourself, go to youtube and look for the Rhodium disassembly video (this will help you a lot). It is not difficult to change any parts in the phone provided that you proceed with caution and take the necessary precautions.
If you are afraid or have never opened up a phone to fix parts, then I would suggest to send it to HTC - this would be devastating if you managed to break up the motherboard by mistake or any other parts in the process of fixing the flex cable.
Tripp --
Did you ever find resolution to your problem? Recently my phone started having the same problem, which I originally thought was related to messing up the calibration file when I put loaded xdandroid GBX0A.
However, it sounds like my problem is pretty similar to yours -- touchscreen works fine when the keyboard is closed, but when it is open it only registers on the bottom of the screen -- which is actually useful in some sense because I can still hit the soft keys in the messaging app and such, but not so useful if you want to scroll using the touch screen. If I play around with the z-hinge a bit, sometimes it starts working -- which sounds like the same thing that you described.
Sorry, I just seen your post but I never fixed mine as I went ahead and bought another phone (Evo) but I did research the problem quite extensively and the problem I believe lies in the ribbon that connects the two halves of the phone. If I remember correctly the motherboard is in the side with the keyboard and that's why when it's slide out, the touch screen won't respond correctly. You can find the part online and replace it yourself. I've taken mine apart and it's not that hard but as said, you need the right tools and to be very careful.
Hi guys
I have tried all the above
Last resort is i got sprite backyup to work
BUT HOW THE HELL DO YOU HIT "NEXT" OR "OK" FROM THE KEYBOARD AS SCREEN DOESNT WORK????
Hello there
Im hoping that someone here can help me since im ready to seel the pho for spare parts... i've tried it all.
Heres the deal:
- The phone boots well and if i connect it through usb to the computer i can even access the folders and all.
- I can take photos (i her the sound of the shutter and all and see the piics taken in the folder when connected to the computer) and screnshots
- I managed to restore the phone back to original settings and even update software with sony official soft.
- Inicialy i bought the phone as faulty to try and fix it since the buyer informed me there was no water damage ( and i can confirm this because the "stickers" only show white). He informed that the phone just stoped showing image on screen.
- I thought it was a problem with the LCd so i bought a new one and replace it. The problem persists. Everything works but the screen.
Any toughts on this one? Could the motherboard be faulty in only one place (image, proximity sensor, etc)?
Thanks for you time
Regards
Try the service manuals...

I have fully same faulty 2nd "spare parts" phone.
All works except screen, all as you described.
I checked, in my case problem definitely in screen because if connect main board to really working LCD panel = screen ok.
And vice versa: if connect normal main board to this probably faulty screen = black screen.
Maybe here broken flexible connector.
Also nothing interesting related to this case in service documents.
a bit of background, i went full retard and factory reset my android head unit, then when the white screen with the crosshair popped up i had no idea what it was, so i started touching the screen randomly. turns out the white screen was the touchscreen calibration, so i ended up ruining my touchscreen completely because now there are giant dead spots on the screen or i tap somewhere and the screen thinks ive tapped a completely different place. my first question, how do i even find out which headunit i have? (i bought the car used and it alreaddy had the radio installed in it.) and is this fixable without going into the device settings, because i cant navigate there. second is there a way to factory reset the device using just the hardware keys?
A picture of your head unit might help.
If that's not enough, you will probably have to remove the head unit so you can read whatever stickers/imprinting are on the unit.
I just bought a PX5 unit, which seemed to be working perfectly until I finished installing it into my car and now it has become unresponsive with a black screen and a yellow rhombus with an exclamation point in the middle (unable to upload image as new user).
If I turn off the ignition, it will turn the stereo off and the android screen briefly shows before going into sleep. None of the buttons are allowing me to get past the screen and in to android. The reset button seems to do nothing, android is definitely running in the background, just unsure as to why this screen will not close. Any ideas?
Hi, I think I saw a yellow rhombus with an exclamation point when I was installing my radio and rear view camera was not connected to the radio. I think that it is a warning about missing video signal when radio is displaying live feed from a rear view camera.
So, one explanation for your issue could be that the radio thinks you are reversing, and the rear view camera is not connected to the radio. If I understand it right, radio can switch to rear view camera display mode based on two conditions 1) canbus information 2) +12v trigger signal.
For the condition 2), you could check that nothing is unintentional connected to reverse detect wire. If that does not help, then you could perhaps try to disable reverse view feature in the configuration menu before installing the radio to the car and/or find a working canbus configuration settings.
Please notice that I'm a beginner with Android head units and your problem might well be something totally different!!
Thanks for your reply. Some of your post seems to relate to my issue definitely, I think it is linked to the rear view camera which is currently disconnected. However I am unable to get into any configuration options. None of the buttons/resets I try get me past the exclamation screen, I can only see android once I turn off my ignition when it tells me it is closing down. None of the various reset button combinations seem to do anything with my head unit either, can't seem to reset it properly. Its strange, I will reattach the camera tomorrow and see if that brings any joy. I don't know anything about this stuff myself but I am wondering if I did something to the head unit to brick the non-android side somehow.
Edit: Unfortunately reattaching the camera did not change anything.
Update. I have managed to find a way in to the Android side if I connect my phone via bluetooth to the stereo, it then lets me use the split screen function via the top bar menu to put the warning screen other screen to the side, however whenever I touch the screen or attempt to use the android interface, my stereo goes back to the warning screen, none of my inputs via the stereo buttons or the touch screen seem to be registering with the Android side? Very confused. I have also tried as many button combination resets I can find and I have not been able to successfully get into the recovery menu, or any change except rebooting.
Was your unit professionally installed?
Also, what did the re-seller suggest when you contacted them for support?
No the unit was not professionally installed. I am not sure how I've become stuck with the problem. I made some minor changes in factory settings but nothing I thought would of caused this. The seller is yet to respond and its been a couple of days, but I have requested the hardware reset methods for this unit or any other solutions.

Check the reverse wire on the back of the unit...if necessary disconnect it to ensure no reverse signal is received.
If your unit can boot into android normally then you will have to figure out why the reverse wire is receiving signal .
Check your connectors to avoid any of them to be loose.

Everything has been disconnected from the unit except the power cable to car and and canbus, from what I can tell nothing is loose. Unit will not boot without the canbus box whatsoever, not sure if that is meant to happen.

Yes, canbus decoder need to be connected for power up the HU. If you dont need the decoder box you need rewire the harness.
I think I am going to have to request a refund and return it. Still no reply from the reseller and I am not sure what else I can try, everything that is not needed to power it has now been removed. I can't send links or else I would update the thread with a video of the touch/physical buttons being completely unresponsive even when I manage to get to Android. The unit has definitely developed a fault and I am unable to reset it. Admittedly it could be my fault somehow as it was working for the first few boots, but unless they give me something to try I am just going to have to send it back.
Quick bump. Has anyone got any further ideas? I bought off Aliexpress so contact with the seller is slow and painful, they do not seem to understand the issue and just keep telling me to disconnect all wires and reconnect. Which has been done many times. If anyone wants to post a link to the video for me I would be happy to send them it privately.

I would start a dispute with them. I had a device that they sent with similar problems and plenty of issues, which they would not help with or would not understand. Best option is to dispute to get a new device or a full refund. Could you send the video?

Yeh I have a dispute open currently, just was hoping it would inspire the seller to actually offer up a working way of resetting the device. Had to add link below seperately as needed to be ten or most posts.
https://www.youtube.com/watch?v=ujHacKESAT8&feature=youtu.be
The stereo defaults as the warning image black screen and I can only get android up using the multiwindow button with a long press. Then the android side will not register any input and will keep trying to put the black screen to the front.
Update: I have been told by Aliexpress I can have a partial refund and keep the unit, or a full refund if I return to China. Anyone have any ideas how I would go about resetting the unit if I took the partial refund? To be honest I think my only option is to return it and get the full amount back but any ideas would be welcome! Shipping to China and awaiting a refund is going to take weeks, would rather just get it working if possible.
deano35: any progres? I have the same problem as you. This is my post from PX5 MTCD/E Head Unit Discussion Thread
" Hi , I have https://s.click.aliexpress.com/e/DtwdJIt its px5, Mtce_gs_v2.90c. Now I have a little problem with rear camera. I bought reverse camera and tried to connect it into front camera input(I was curious how it would look like) and since then its stuck on camera view. Even after disconnecting camera. Only solution was disable "prohibit reverse" in factory settings menu, but with "prohibit reverse" disabled is obviously not showing reverse camera when I gear the reverse down. Everything is shown in this video. https://photos.app.goo.gl/XbYUHApzT8qTezkq6 Thanks for any advice. "
Take a look on the video, its similar as yours.
Regards,
I tell you what happened, about two years ago I bought this unit and everything worked fine, in fact, quite satisfied with the cost / performance ratio, unhappy with certain details that I have read in other threads for not being able to connect my ELM 327 to the radio bluetoh, annoying noise of the internal processes of the radio, among others.
Three days ago, my wife connected a damaged cable to the usb port of the radio to charge her phone, at that moment the radio went blank, as in short, when I realized I disconnected the cable, the radio restarted and everything seemed to be Well, when I got home and turned off the car, the radio as usual also turned off, but with the difference that the LEDs on the buttons were still on and the annoying noise from the internal processes of the radio was heard (it was not turned off totally). Another problem is that the physical buttons were deactivated when turning on the radio again, for them to work I have to reset the radio, but when turning off the swich and turning it on again the buttons are deactivated again.
To rule out that it was a software problem, I tried to do a factory reset, I installed several updates that I found in this forum and in a Russian one, in principle the updates complicated my radio more, leaving the mirror mode, etc. I insisted and got a proper firmware and it was her again, but with the same problem I had been telling them.
I decided to open the radio and found this:
It consists of two board, one where the tablet is concentrated and another where the amplifier, outputs, etc.
As for the amplifiers and the output, etc. I saw that there is a big stain, at first glance it seems that it was the filter that spilled, in my opinion (I don't know much about electronics) it looks like Flux or a glue that was left at the time of its assembly.
On the tablet board there is another smaller spot, it seems burned, but it is the same substance as the other board.
My questions,
Will the problem be physical, the filter exploded? (does not look bloated or anything)
It will be software, should I reinstall the software through the computer and not through a ZIP file update?
What part of the engineering menu could modify the parameters to try to solve?
I await your diagnoses and possible solutions, thank you very much.
