Check the cable is seated properly & is the right way up. Adjust & retry. If always the same result it might be your digitizer is damaged/failed/not connected properly.
Possibly you can also try a screen test app (if they still work on Android Pie) if your screen is not black

Weird touch screen on Trinity

Hello,
My pretty new Trinity has a weird feeling touching the screen. It is very precise and seems to work ok, but I feel as there is some space below the surface. It has not a screen protector yet.
Is that normal or I have an issue?

It is normal. I've had this on serveral pocket PCs I've had (Wallaby, Blue Angel, Wizard).
100% normal.

Screen Calibration?

My screen is not responding to touch so easily anymore. Right after re-booting, looks like the mouse thinks I am pressing on the screen when I am not, and then when I touch the screen, mouse is not where I am touching.
Are there any screen calibration tricks that I can try before sending back?
Thanks
Control Panel, Tablet PC settings is where the screen calibration is.
Have you fitted a screen protector?
If so, try removing before taking the big step of sending it back.
The touch screen software can freeze!
I use the Proporta leather case which has two small spaces for SD cards in the top. I f I leave Vista running and close the case to go to the car, the touch screen stops functioning after about 2 minutes constant pressure on the same spot. Sleep and Hibernation do not help, although the startup window reacts to touches. Only restarting Vista helps.
I didn't notice the same problem on the WM side

Thanks for the screen protector suggestion. Bingo. I took it off got a response on the screen, and then re-fitted the protector and all seems to be working well.

To clarify. It is your LCD that is broken, your digitiser may well be but as you can not see to test...
One way would be to hook it up to your pc, run mymobile, and see if pressing the digitiser registers the command when viewing it on mymobile.
Stu
thnx for the reply .......it does give a responce when i touch the screen ....i mean the lcd brightens up....!!! btw what is digitilizer..???
Digitizer is the thin screen above the LCD screen which recognises the stylus/finger touch (Analog) input into Digital Signals.

Need help with strange screen problem [For the smart guys!]

I have just replaced my samsung galaxy s4 screen lcd and digitalizer. When i boot up the phone the screen has an yellowish white tone.
When i plug out the bottom buttons and the charger cord inside the phone, from the main board. The yellowish screen goes away, and i get a nice white toned screen.
Is this a hardware or software problem?
Does anyone have a clue how to fix it? any sort of contribution would help!
Sorry for bad english, it is not my native language

Well, the reason i switched lcd was because it broke down when i droped my phone on the floor, so that one doesnt show anything...
I can see my background picture in behind, when the screen gets yellow and i open an app. the phone is also rooted

Problem after the screen change

I changed the display , the touchscreen of my one plus. The screen is a lcd and not amoled but works perfectly. After 3/4 days by using it , it started to give me some problems and the only way to fix it is going on the twrp and go back on the old backup. The duration of the problem is not the same but change. This problem comes up when i try to open an application, unblock the screen or after ending a call. The screen just go off and doesn't turn on again, if it gets restarted it will work again but once i get the pin screen it only show it for 1 second and then the phone just turn off auto.

Could be proximity sensor getting blocked. My friend also replaced his screen with an LCD panel. This problem occurs when he calls anyone, so to restored back he uses power button and screen switches on again.
