Xiaomi mi smart 2 projector screen issue

Hi Community,

I have a Mi Smart 2 projector and it has a screen problem where the screen developed dead pixel lines and turns green. I've already replaced the DMD chip but still having the issue. Any idea what could be the problem? Thank you.

So, I've checked the new DMD and it's gone. I'll try to get another one but I'm worried that something else is killing it. Anyone any idea? Thank you
