Touch screen stopped working on " Klyde (KLD)" RK3188 unit - Android Head-Units

Hello!
I've got a "RQ1222e Pumpkin car stereo" (seems to be a Klyde (KLD) unit with RK3188 and 1024/600 screen. I installed a MTCB/C ROM from Malaysk on it some month ago.
Everything worked fine - then suddenly the upper top of the touch screen was not responding any more.
Some weeks later, the lower part also stopped working - and now the hole screen is not responding any more.
Only the buttons are responding, the rest of the radio is still working.
I think, the touch screen is defetiv. I already opend the radio and repluged all connectors - this did not help.
Pumpkin says, they don't have a new touch screen for the unit. Is there an "universal touch" which I can buy and connect? It is a 7" unit.
Attached some photos of the screen, maybe this helps?
Many thanks in advance!

I have the same issue. Any help ?

Hello! Sorry, I forgot to post the solution here. I repaired the radio by changing the touch screen.
I bought this one:
#Aliexpress € 8,68 5%OFF | Auto DVD-navigation 165*100mm 164*99mm 6pin gt911 kondensator touchscreen.

The touch is fixes with tape in front of the LCD an can bei changed easily

Thanks, will open it up on the weekend.

GS MTCD Android 6.0 HeadUnit Soft-Buttons Issue and mirrored Touch Input

Hi folks,
I have bought a Xtrons PB96MTVAPL last week. which is a GS MTCD PX5 Octa-Core HeadUnit.
I am very pleased withe the performance of the system and the UI in general.
Since i am pretty new to the matter i played around with it a bit today.
I wanted to optimize the Factory Settings today and "accidently" pushed the "Reset Soft-Buttons"-Option... resulting in directly disabled Soft-Buttons... which is not preferable on a "Soft-Button-Only HeadUnit".
I also have a horizontal mirrored touch input now wich is really crappy and twists my poor brain...
I have contacted the Xtrons-Support but I have the feeling they force me to return the Unit which i dont want....
Is there maybe a way to remap my MCU Softbuttons?
Is there anybody who could send me a copy of his dmcu.cfg for the PB96MTVAPL?
[solved]
Hi,
i solved the issue myself by using the "Reset Toch Screen" function. One has to point at the upper left and lower right of the touch area. After that one can remap the softbuttons.
it was quite a struggle getting there with a totally flipped screen.
Hi. I am also interested in you unit. How is the radio reception, the audio quality and generally the unit? I would like to send me a quick video if you can or upload one in youtube. Thanks

Joying JY-UL135N2 - Suddenly lost touch feedback?

The other day in my truck my Joying JY-UL135N2 lost all touch feedback. The hard buttons work but I cant use the touch screen at all. I reflashed the newest firmware but the problem still exists. Ive had the unit since it was released with no touch screen issues. I can use the unit via usb mouse however could this be a hardware issue with the digitizer or has anyone experienced this issue? Thanks.

Black Screen on my Joying DE-JY-VM130N2

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.

Car stereo, temperamental black screen

Hi guys,. I own a a-sure 5.1.1 on a opel canbus. The past month I’ve had a temperamental black screen issue. It goes blank but touch still works. When it goes blank it takes a few days (engine starts) for it to come back on. Then it works fine for 5mins or a week,. It’s not been software updated since I’ve owned it (5yrs). Hard reset doesn’t solve the screen. But it has helped in the past.
I’m not to sure,. But I think my car heaters are encouraging the blank screen (heat)
I’ve stripped the stereo and rebuilt it (ribbons/wires).. put the stereo back in the car and the screen was still blank. I not used the car Sunday.. but today Monday the screen is working all day. I checked it on all work breaks.
Any suggestions?
First of all, your question is not related at all to Android Auto.
Second, it looks to me more as a hardware problem, like a loose contact of the display. I had a similar problem with a Blaupunkt car radio with a detachable panel. One day the lcd display went black and never came back, but the radio and all its functions continued to work fine.

Dasaita PX6 7" - touchscreen partially working

Hello,
i have Dasaita PX6 7" without hardware buttons and some time ago the touchscreen started to do strange things like i'm driving and i hear the media makes *bop* sound as if i've touched the power touch-button and the screen goes off or it launches a program as if i've touched the screen over where it's icon is.
Now it seems it stopped doing all this but a portion of the screen is just not working, not responding to touch.
The pic of the unit is from the web but mine is the same. I did the color rectangular areas tho to show and say - the green area is responding to touch, the red area is not responding
I write for over a week to Dasaita on Aliexpress where i bought the unit for solution or for new screen - they just read, no answer. I also write to their FB page - no answer.
Because the portion of screen which is not active i can't drag and drop icons from other screens to main screen - i have mouse, but i cant select and drag. Any suggestions?
And please tell me if i can fix this touchscreen (maybe it delaminated somewhere and its not making contact) or where i can get new (because of high chance to ruin this when trying to fix it).
Thank you
Have you ever recalibrated the touch screen?
I don´t know how it works on yours, but for a couple of units it works like all 5 fingers touch at the same time and hold it until you get a marker on the upper left screen.
Touch it as exact as possible and do that for all corners as you get the touch point visible.
For the buttons on the left side you should have a setup in the settings menu.
Hi, i watched videos about the 5 fingers touch but it doesnt activate on mine.
I entered the factory menu /with the 126 password/ where are similar functions and tried them several times just to be sure - no change.
The buttons on the left side are part of the touchscreen even tho they are on the black stripe, its jsut painted, it dosn't matter.
BR
In this case you should get in contact with Dasaita and/or the seller.
May be there is an issue with the controller or firmware.
