I cleaned my projector and now it gives only negative image. I took it a part while cleaning, but I didn´t do anything to the electronics inside. Any ideas what´s the problem? Everything else seems to work ok.

If you pulled the polarisers off of the lcd, then it's possible that you have put them back in the wrong order.

The parts are made so that it's impossible to fit anything back in wrong order(least I think so). It includes mainboard in 2 parts and lcd display with small board, practicly including only capacitors. Display part is connected with thin ribbon cable to mainboard and I just tried to turn the cable backwards so that I could see if that wire is broken.

I'm totally lost cause there's no jumper or switch I could turn. There's neither option in menu to do negative image so I'm totally lost with this item.

I managed to get another samekind with different motherboard. I found out problem is in motherboard and because it's different I can't find broken part. Does anyone have bios for this? Text in bios chip is vp-800 v3.31.
