So I started my CX-5 about an hour ago to be greeted by a black screen full of flowers. Literally. No idea why. This happened one other time, and it seems as though once it powered completely down, it comes back up fine. I have the timeout at 2hrs, so I have to wait quite a while to see if it's going to be ok.
I tried to reboot the unit by holding the reset button down, but all it does is put it to sleep. Actually, a short press caused it to mute (literally displays 'mute' on the display), and a long press puts it to sleep. Tried the press it till it goes off then release, then press again -- doesn't do anything but wake the unit up again.
The steering wheel controls all work fine. When I parked it last night I had the radio playing, and it was still playing when it started with the black screen. Volume and fwd-rev buttons on the SWC work fine. None of the capacitive buttons on the LCD do anything except home and power. Power puts it to sleep. Home displays the launcher screen (Car Launcher Pro).
If I press any of the app buttons in car launcher, they send me back to the black screen. Pressing the speed in the launcher switches to the trip display like it should.
Anyone ever seen this?
Anyone know how to actually reboot the thing short of pulling the fuse (if that would even work)?
The car has resistive steering wheel controls and *also* has a canbus decoder to tell the Bose amp what to go do with itself. I didn't actually have to use the KEY1 or KEY2 - I assume that the Mazda ISO adapter that they sent has this built in but I dunno.

Thanks for any help...
That's happened to my MTCD a couple of times and seems to be when Android's user interface hasn't loaded properly for some reason.
Pushing a paperclip into the reset hole until it reboots normally fixes it for me.

Reboot with a paperclip as other guy pointed.
Your can bus not only plays with Bose amp....it gives you the reverse signal for the Camera as it is coded by can bus.
You have nothing to do with cables as they are properly wired for your installation

I have tried the paperclip method. All it does is put the thing to sleep. Doesn't matter if I hold it for 5 seconds or a full minute the result is the same.
the flowers thing is one of the default wallpapers
Hi !, try this......

this video shows how to enter recovery, you need to re-flash the firmware one in the recovery.
Good luck

@DudeInMyrtleBeach You have the same Head Unit as mine. How is it now? I have not updated mine yet. Can you update me on how your car radio is right now?

@Sylvan15 -- I had the flower screen one more time after I did the firmware upgrade, but I was able to reboot with a paper clip and I have not had an issue since.
Thanks

I got the same screen in my HU but only when car launcher is installed. If you remove the launcher that screen will not show again. Maybe is an issue with the car launcher with the units. I am using an MX (witson) version 1.93
I thought it might be car launcher. I haven't had any issues in quite a while though.

All the buttons, including the volume knob stop working.
It has happened several times on my android 5.1.1/mtcd/joying unit.
When it happens the boot process is strange. It spends a while displaying the car logo, then it displays the desktop for a second or so and then it displays the car logo again. It sort of looks like it boots twice.
Wiping the dalvik cache does not fix the problem. I have to factory reset or wipe everything from recovery to get the buttons working again.
I am currently using malaysk rom for MTCD units but I had exactly the same issue on the stock rom.
I think the problem is related to autostarting apps on reboot.
Today it happened after I installed the Sygic speed camera/traffic alert app. Everything worked fine for a while, until I chose to auto start it (from the settings menu inside the Sygic app), rebooted, and the buttons no longer worked.
To check if the autostart option really caused the problem I installed the app again, chose to auto start from the settings inside the app, and the same thing happened. Buttons no longer worked.
The issue is not specific to Sygic, as I have had the same issue with other apps.
Now I use tasker to autostart the app. It has survived a few reboots. I hope it lasts.
Does anyone understand the boot process on these units well enough to help debug it further?
It would be nice if I could fix it the next time it happens, instead of having to wipe/reinstall everything.
It seemed to be completely random for me... and it stopped happening as randomly as it started.
I posted the process I went through to get them back (reboot, reboot to recovery, reboot again, etc) but very intermittent.
I experience this whenever I reboot from the power icon in the taskbar. It seems to have started after upgrading to Malaysk's version 4. I have verified this on two Joying units. My workaround is to reboot with the reset button when I have to.
I have not had any apps autostart since the last time it happened, but the buttons stopped working again a few days later, and the "double boot" came back also. The reset button did not help.
A factory reset from the settings menu made the buttons work again.
I was using the latest joying rom and MCU. Spotify, iGo navigation (from joying) and the TomTom speed camera app were the only "extras" installed if I remember correctly.
I am about to give up on the (JY-UL135) head unit now. Unless someone has suggestions on what to do.

xdamember2, i think you are right. Power icon in the task bar is the root of evil.
Today i've had the same experience. But with the buttons, the sound had also disappeared. Pushing hardware reset button had fixed the problem.
So I suggest to remove power icon from the task bar.
This happened to me yesterday, but as well as buttons/steering wheel control, all sound output stopped working! No radio, music or navigation sounds. Tried a reboot, but in the end only a factory reset did the trick as specified previously.
Very frustrating!
This happened to me again today for the second time. While driving the screen turned to white/black static like moving artifacts and the sound cut off. After holding the power button to reset the buttons are not working. I'll update to Malaysk's Rom v5 now but looks like my apps are wiped again...
i've been on v5 for the past few days and i haven't witnessed this behavior.
Any luck with the buttons and sound stop working? It`s the same with version 6 of this ROM which i like way better then the stock ROM. I`v noticed that any other reboot except the standard one, when the HU shuts off by it self, will make buttons unusable and no sound. The first time it happen to me was when i did some changes in the "factory settings" menu that needed to reboot the device. The only way i managed to fix it was to do a factory reset. Tomorrow will try to flash the same ROM (V6) without wiping to see if this will fix it,because they don`t work again now after rebooting from the power icon . Lets hope someone finds solution for this annoying issue.
MY FIX for Volume knob not working on Android Head Unit
Hi All
I updated my generic Ford Focus PX5 android head unit, and after much swearing and reading on here, I still was unable to fix the top left volume and top right tuning rotary knobs as they had stopped responding.
Eventually i started mucking about with Factory Settings and in the "OTHER" section I looked at "Knob Mode"
Experimenting with the various settings I eventually determined that for me, "2 10K/20K ADC Ports" works. I now have fully functioning controls.
I hope this is of some help to you guys!
I had been fooling with the settings of my Android head unit and some days later realized my volume knob wasn't working. That knob was a big factor in my purchase of this unit. After fooling with a dozen or more logical sounding settings, I happened upon the setting which had to do with 'Key lights'. Here's the fix:
From 'Settings' go to 'Factory Settings' and enter code 8888. Go to 'Key Light Settings'. On 'please open the debug button lamps' press 'OK", slide the screen up and turn off 'whether to turn on the colorful lights'. Back on out and the volume should now be working. Hope this helps

I recently bought a new android head unit. All are working well except the original volume knob of the car. Sometimes i must turn it 4-5 clicks for the volume to move 1 click, and other times i may turn it 10-15 clicks and the volume does not respond at all. This is very frustrating! I found a solution on youtube which says factory settings-other- and uncheck the wheel3 option, but my head unit doesn't have this option at all. I hope your solution will help me!
Update : I searched for this solution you mentioned but this option does not exist in my factory settings with 8888 code. Only car logo. I dont know what to do....
Hi,
my name is Josemari, from Spain.
I have a TF101 with dock (and original rom from Asus) that does not display anything on screen since a soft fall from 10cm (daughter in a very very small chair).
When i plug the charger, it works (and beeps -charge-). When i plug the dock, also beeps. When i connect through hdmi output to my tv, it also works. I can use the tablet perfectly with my fingers.
What can i do?
I disassembled the tablet and i checked all conectors, but i do not see anything wrong.
Thanks.
I had the exact same problem. Even though it has fallen before without a problem, in my last 2 cases it was a loose connection for the video screen. I had to open up the tablet and simply push the video connection back on all the way. It's rather easy if you're familiar with taking things like this apart. Make sure you are careful when you re install the side trim that holds the buttons. It's easy to break the red tabs that press against the buttons. It may be helpful to you to look up a disassembly guide. I believe if you google the specific issue you will find pictures. Again it's been a long time. Hope this helps
I have the same issue since a few days.
Difference here, when I boot up (holding power button until reboot) the screen is on (Asus logo and boot animation)
The display goes balck / disappears (backlight off) when the lock screen comes up.
Checked the inner display cable and connector with no success.
Did a factory reset and it was working again, until I changed the brightness to a higher level. Then the screen was dark again.
I managed to change brightness to a lower level using the working HDMI interface. After that I switched the tablet off and on and the screen was lit up again.
Another effect: when power adapter is plugged in, I can go to a higher brightness level until the backlight turns itself off.
It looks like a hardware defekt of the backlight electronic to me. Couldn't find any spare parts, such as backlight inverter, though.
Can anybody confirm this or knows how to repair?
I will use it at 30-50% brightness now and see if it gets worse over time.
My MTCD unit touchscreen or soft buttons don't work after wake up after key off.
I have to key on - key off 3-5 times before they work. Once they are working unit performs perfectly until the next key cycle.
I think it's a software issue but is it Firmware or MCU
I am seeing the same intermittent problem with my PX5 unit, screen is black and push buttons do not work, cannot enter recovery mode either, then for no apparent reason it will work normally for a while.
I suspect there is a hardware fault with mcu or maybe even some other failing component or poor soldering. I have raised the issue with the seller but would be interested to hear from others as to what they think the likely cause may be or what can be checked to narrow down the problem.
As far as I can tell the battery and acc voltages are good but 7805 and 7809 regulators do not appear to be powering up in my case?
Mine isn't as bad as the unit will continue to play music from the point key is off and steering wheel controls still function.
Hello, did you manage to solve the problem? I have the same issue after upgrading from PX3 to PX5. The unit works fine after booting (if the power is disconnected). The problem is after wake up, since it does not support to turn it completely off any more.
Did you do something before it happening (e.g. a firmware update, mcu, or?).
Thank you.
I have the same issue with my new GS PX5. Before I had another one which hadn't this problem.
My problem seems to have been solved by updating the MCU to HA 2.61. Now the menu to control shutdown behavior shows up in the Extra settings and I chose the 30 sec delay.
Not sure if auto sleep works too, need to try.
Alex.
My top soft buttons stopped working.Everything else work ok but all the top softbuttons doped working. What can I do?
As the title says, every day or two the screen stops responding to touch, I have to hold the power button for 30 seconds to force a hard restart or put a pin in the reset hole on the front, then it's fine again for a day or two.
I have updated MCU from MTCE_GS_V2.78 to MTCE_GS_V3.40, and Android from HCT_PX5_6.0(20171023) to HCT_PX5_6.0(20171227), also removed front panel and DVD player and re-seated all 3 ribbon cables connecting the front to the main unit (2 small & 1 wide) to no avail, An ideas? or is it just giving up after 3 years?
Thanks all
I'm having the same problem, only thing is now its become permanent. I've tried everything from MCU updates to stripping down the unit to barebones and checking connections. Its not just the screen touch, its the touch panel controls as well. Did you get thsi resolved?
Unfortunately not, sometimes it comes back to life, I quickly play an album, the screen jumps and flashes then goes black, no touch working but music keeps playing, sometimes my whole journey to work is in silence, I'm learning to live with it :laugh:

Model Name:

Bought it in 2019, it was working flawlessly....
I now want to sell my car with the hu, and went into the factory settings with the pw: "126" and resetted the hu ("Tablet is restarting" was shown on the display)
After that, no reboot from the hu.
Screen remained black.
I pushed the Reset button in the lower left corner, nothing.
I held down the Power (volume knob) Button for more than 10 seconds.... Buttons are flashing 3 times....nothing. Screen remains black.
I disconnected the hu fron the car, waited overnight, connected it again, but nothing, no boot sequence is shown, screen remains black.
Can somebody tell me what to do to get this unit working again?
Best regards from always rainy, gool old germany
I can not remember exactly but this happened to me. I followed the information in his signature from this post somehow.
Blank screen and confused
I have a px5 radio packed as kanor. It is a px5(1024x600) running 8.0 with mtce_kld_v3.01_1 and has physical buttons. It was running ok. I went into factory settings and changed the led color and changed the mapping on one button. It said it...
