[Help] black spot in screen

Hi, I need your expertise, I just turned on my pimax 5k+ and I see a black spot surrounded by red on my left lens. What kind of problem is causing that??
I upgraded to Pitool last time.


Hi RDzzz,

Please kindly attached this picture, our technician will diagnose the problem.

But from our experience, it might be the burnt screen.

Thank you for your response.
you’re assuming the screen is sunburnt? but I don’t have a window in the room where I’m playing…

I submit a ticket on Support Page And here’s their response:
( Disappointed to be out of warranty for a short month. )

" Thanks for your reply. But I have checked your order and found it has passed the warranty period. We offer one year warranty. You received the item on Feb 2019, and now you contacted us in Mar 2020. So I am sorry we cannot offer free warranty service. If you want to repair, you need ship it to us at your expense, but you need return to China for repair. And also you need pay repair fee. If you need repair, I will offer you the quote. "
