Thanks for reading and getting back to me, Descalabro.
I actually removed most of what it had inside, lol.. All layers, most parts, also colorwheel and optics, as in lens house. I`ve used a combination of Ear cleaners, Special cloth and finally a little bit of canned air, not inside lens house though. I solved one problem (wouldn`t turn on due to dust on colorwheel sensor), but made this shadow issue insted, as I digged deeper than I had to.
I don`t have any source hooked up to it at the moment and as you figured, it`s most noticable in white. I`ve posted some on black with the one from projector, if yours is better to make conclusions, then i`ll get it hooked up on it.
As you say, it does look like something isn`t aligned and I do have my eyes set on one part, but fare from sure and I have tried changing that once with no major difference. I screwed on some screws, that could have been sealed to adjust alignement, otherwise it must be inside lens house, or lamp that is not fittet the hole properly I guess? I`m also wondering if I damaged the color wheel or something, but then I don`t understand why it`s only in bottem and right side of the screen, where the colors are darker/burned looking, due to the shadows or whatever it is?

What do you mean by "everything"? Did you remove any of the optical or electronic elements to clean them, or did you clean everything in place? And how did you clean? Compressed/caned air, or did you use other method?
Can you post an image of this image projected so we can have a better sense of the alignment?
I attached an inverted one if it's easier to see the shadow.
