Dear, have a video projector that I have used for about 40 hours. But I didn t use it for years after that. When I used it again many years after letting it in its case, few minutes after turning on, it give some Kind of purple patchs.
I publish a link to youtube to let you see how it looks. If someone can help please.
I say again that the problem appaires every time, few minutes after turning the projector on.
Sorry for my bad english.

Looks like it might be dust spotting. You probably have dust in the light path (inside the projector). This can often be cleaned with canned air. You will have to take it for professional service if that doesn't work.

Thanks for your answer. I have tried now the eco mode, and in this mode there is no problem. I have also tried to clean it With pressured air from the the placement where the lampe is installed but without any result in normal mode.
