Hi, We found a fairly old projector about a week ago (Philips Projector Proscreen 4650 : http://www.projectorcentral.com/Philips-ProScreen_4650.htm and we plugged it into a nintendo wii and the TV and everything worked perfectly. However then we tried using it with a pc and noticed the colours seemed to be mis-aligned. We switched back to using the projector as a tele and everything was fine again. Then yesterday we tried using the projector with the pc again and it worked fine for about 3 hours, then the colours started slipping and became misaligned again, so we tried using the projector with the wii and as a TV but the colours stayed mis-aligned. What could be going on? From reading another post on a similar type problem you guys thought it might have been an LCD panel mis-alignment, however it's rather strange because before it was only misa-aligning every now and then not all the time. Here is a picture of what it looks like now;
