My projector is flickering?

I have about 10 of these in the school I work in, most of them have gone mental flickering, my solutions has been to open the covers remove the bulb and carefully using a compressor blow all the dust out..This has worked and cured them in about 6 out of 8 cases

Hi Pascoal your projector is a dlp projector by design if you scan your eyes from one side of the screen to the other quickly the colours will appear to separate or flicker, this is normal hiwever if you stare at a spot on the screen and it is still flickering its possible that the colour wheel is on its way out or there is a problem with the video input circuit in this. Ase it would have to be serviced by a qualified engineer these are not problems that can easily be fixed. I hope this helps Regards Ant

There is a good chance that the image processor is over heating due to old heat transfer paste on the heat sink attached to the end of the lense assembly, dismantle, clean and replace..... See optoma HD200x Cheers
