i also have similar or same issue with my p11 display. did a factory reset and it did not resolve it. may be a loose lcd connector but that is kinda doubtful. sure hope it is not a bad connector on the motherboard side. would like to open it up and see and then try replacing lcd if needed. but the issue is havent found how to open it up. there is 1 video on yt but he skipped the removing the back cover which is what i need to know. it feels like it is on really tight and prying on it like you normally would as other tablets would hurt it, there usually is some give. i think he skipped showing it because he hurt the frame.
Update: I found a yt vid of a similar tablet and followed it and it did provide the trick of opening it up. Trick is to remove the sd card/ sim tray and gently pry inside it and push the display away from the edge just enough to get a thin spudger in the gap to start the process of separating the display by popping the tabs that are keeping it in place, there are many of them like 1 every inch or so. Now I have to admit that I still have not done the repair yet because it might be the ribbon or it might be the lcd. Guess I will just get both. Another update coming after it's been done.

I can't answer your question but my tablet has exactly the same problem. It was bought on Amazon, to whom I've returned it to but they are claiming that the issue is caused by "Customer Induced Damage". The tablet had not been used much, protected by both screen and case, no visible damage to the casing, not dropped.
How did you resolve your issue? Amazon are quoting £221.26 to repair, I bought it for £267.00. There's no explanation given as to why they think that I've damaged it, I'm awaiting a response from them.
Any help would be appreciated
