I am stuck at school installing windows 7 :rolleyes: and I came across something to fix.

It's a sanyo plc-sw15 data projector, and whenever something is plugged into the 'computer in' input the image gets all quivery and jumpy. It only occurs on the digital inputs (component video) and not composite video in or s-video.

I have pressed reset on the back and the only material i can find is the manual.

Can you try a different cable and different device with digital output?

It is not the cable as I have used 3 brand new cables. I have used my laptop on it with s-video no problems, same with the DVD player, which also works with composite. However when I connected the player to the projector with component, it was the same flickery image. I hope to post images.

4192 is computer input
4193 is s-video input

try set the resolution and the refresh rate manually. Had the same prob with at Eki projector (very old mind)

It took a lot of fiddling but eventually at a res of about 640x something and an unusual refresh rate it worked

I did try that and it didn't work.

It has only been doing that for a short while

According to this, it doesn't do digital, only analogue, also only 4:3 aspect ratio (maybe you're trying to display widescreen input?); does it have a pal/ntsc setting?
Maybe it needs repair?

Just shooting in the dark here, but maybe there's a dodgy connection between the component video socket (is this the D-shaped VGA connector or something else?) and the rest of the electronics of the projector?

If it's a new problem then I guess some fault in the video processing circuitry probably

D-sub VGA is analogue, Component is also analogue. Just FYI.
DVI & HDMI are digital
