Question about Sanyo PLC-SW30 Multimedia Projector
My projector is showing a large blue dot on the screen, and im stumped to why this is happening. i've cleaned the lens numerous times and i've even tried replacing the globe, still no luck.
If anyone wants the service manual for this unit.. Here is is. free.
Ive fixed many of these projectors polarisers.. temp sensors.. etc.. Found all the solutions in the repair manual..

I agree with Mark Webber, as I had the same problem with a projector. It was probably caused by "burnout" as a menu message box was left sitting for hours , if not days, displayed on the screen. It left a green, almost square area. I took the projector apart and managed to remove the damaged polariser, but when I contacted a service centre to get a replacement part they told me it was not a viable repair for them to do, nor would they supply me with a spare part. real shame, cos i am sure it will be a relatively cheap component. Hope you have better luck than me

This is going to hurt..
You probably have a polarizer failing on one of the LCD panels inside.
There are 3 of these in LCD projectors, red, green, and blue. They all get the light fed into them, that light is then combined and fed through the projection lens.
You will need to contact Sanyo to find a service centre to replace it.
