Hi,
After installing Malaysk 3.3 version on PX5 4G i have a very strange issue never seen before.
When I touch the screen in one spot it seems as if i touch it in multiple spots at the same type.
When I use the keyboard I can't type, If I press (A) for example they screen will pick up multiple letters at the same time, example ( ADUBG3)
Any ideas, I have configured the touch panel multiple times but no luck.
Thank you
The FIX
Hi again,
Solution to the problem.
I was setting up my Unit on my desk, using a 12V 2amp power adaptor.
The problem was the power.
Once I installed the unit on the car battery the touch issues went away.
It seems that the unit needs full battery power for correct setup.

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.

My top soft buttons stopped working.Everything else work ok but all the top softbuttons doped working. What can I do?
I seem to be having an issue with this radio on cold boot; The issue that occurs is when I turn the car key nothing happens (radio acts like it is dead). At this point I have to press and hold the RST button until the lights blink many of times (sometimes this procedure must be performed 20 times) before the device will come back to life. This issue only occurs after the car has been off for more than 2.5 Minutes. Does anyone else have this issue or know the fix to this issue?
I have tried updated the MCU and the Android software to the latest android revisions to see it that would correct the issue, but it does not.
Any assistance is appreaciated.

That's an odd issue. Is it can bus connected? What does the vendor suggest?
Same car and same unit. But i dont have those issues. Check all connections. If it still does not work, bring it back and buy another one.
Non canbus connected unit, vendor was suggesting that the connections were loose but I checked them and even tried the setup on a table top power supply and got the same results

@effectPet has the best answer.
Thanks everyone for the help I will be getting this unit replaced
So, have a bit of a situation and not sure what to do.
My touch screen is working, but only to a point. Only the top status bar and bottom about the same size does not respond at all across.
I've attached a picture as an example of which part of the screen highlighted in red does not respond at all to touch. Everything else not highlighted in red works fine.
Have used my mouse to access boot recovery mode, reinstalled hal 9k mod rom, wiped cache / data and it made no difference.
Even updated my MCU to the latest version available for HA unit, and attempted to re-calibrate the screen via extra settings.
Not sure if original factory rom will fix this, but would like some opinions.
maybe take it apart and check the screen connector is in correctly, sounds like a hardware not software problem.

Hi,
I have similar problem on my px5 seicane unit. the bottom part touch screen won't response or acting without touch after wake up from sleep. restart the unit would result the issue.
wondering if you have resolved the problem? If so is that hardware issue?
just realized the touch screen issue I have on my headunit is probably hardware issue.
in the past I have to re-start the unit, that actually fixed the problem, don't know why. but now I just push the touch screen with my palm firmly. that would fix the problem as well, and last much longer (3-5 days). haven't get chance during the weekday to open up the unit. but at least it worked. and probably proofed this is hardware issue.
I have a Joying unit with a PX5 board. I also have the same issue as the original poster.
I would also say this is a hardware issue. Mine was fine with both the original PX3 and PX5 for a while. Now it is increasingly getting worse. Resets do nothing to solve the problem.
I live in a hot environment. Maybe that is a contributing factor?
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:
