Touch buttons & small portion of touch screen not working - MTCB Android Head Units Q&A

I have a Joying 1024x600 touch button unit. I am having an issue where the touch buttons don't work and the small portion of the touchscreen is not responding to touches.

The line that is drawn on the screen is where the touches stop at anything left of that including the touch buttons do not work.

I had the same issue (could not touch status bar ) and I had to replace the touch screen digitizer . Replacement part found here for about 16 GBP.

Do you still have the part number? I have the same touchscreen like shown on the photo and the only number mine has is "jr-007-01" with that one i cant find anything

Same problem here. How to finde touch screen ?JR-007-01?

I just had this problem today. My HOX screen is not responsive on the middle part of the lcd. The part where the blue line not connected is where the problem is. I've found that the left side of the screen has a really tiny crack. I suppose I have to replace the screen. But I don't know if I have to replace the digitizer only or replace the whole lcd itself. Has anyone ever encounter this problem.

I had a similar problem but at the bottom of the screen. Got it repaired by HTC under warranty. As yours is cracked they probably won't honour the warranty. Afaik you'll have to replace the whole LCD/digitizer assembly as the digitizer can't be replaced seperately

[Q] HTC One VX repair

I found this phone on the street, face down. The lcd and touchscreen were completely smashed in and destroyed.

It did charge and power on. I heard the startup chime and the volume rocker made sounds that indicated that the volume was changing. I removed the removed the touchscreen and lcd, cause glass was falling out.
I am considering repairing the phone, but now with the screen removed, it has ceased to power on. The most it will do is flash green then 2 seconds later flash green again. Is it a goner, or could I still repair it? Do phones refuse to start without the screen/touch screen?

Proximity sensor is covered - Screen always black during calls! How to fix? LG E980.

Hi,
After screen digitizer replacement, I've found that the proximity sensor works very strangely.
Sometimes, it can spot something and stops showing as "covered", but immediately after reboot, it always shows as "covered". That is, the distance detected is always at ZERO cm (near) and never goes to 5 cm (far) as it should be.
How am I supposed to fix this? The "Proximity Fix" app does not help.
How do you fix this after screen replacement?
As you see in the attached picture, the "sensor last covered for" value keeps increasing every millisecond. In this screenshot you see it as 7000 something ms.

Right Side Unresponsive??

I woke up this morning and the right side of my screen isn't working. It is extremely unresponsive. It still registers touch but the device isn't pushing the pixels (ironic isn't it). It seems to be a hardware issue even though I pray it's not. When I tap the tablet it updates the pixels. Has anyone experienced this? I've added pictures below.

Search for split sccreen on lg devices. I belive it is known there - definitely hardware and RMA.
I had this on my pixel c. There were cases on some lg phones a few years back. It's hardware. The only resolution is to RMA it.

Grey halo on screen

Hi, I have a old ZE550ML that had a dead battery. In fact, I abandoned the phone beacuse it bricked two times (bootloop and black screen) due to the faulty battery. Now I bought a new battery and I followed the unbrick guide but I'm facing a new problem. I can hear the phone booting and entering Android. If i touch the screen I hear sounds but all I can see when I unlock the phone is a grey halo.

If I long press the power button while in Android, sometimes the display changes to this:
The screen was working before the last bootloop. Is the screen broken?
Thanks
EDIT: I discovered that if I twist the phone, the display works, so I think it might be a cable problem
