|
|
I am suffering from really low output on green when I feed a scaled/processed ( via Quadscan pro) signal to the projector. You can see the image on the green raster but the output is too low to be seen on screen. The red and blue are fine. This does not happen when feeding sd to the projector direct from the dvd player. The problem seems to be the Barco as the same setup (scaled) into a crt monitor was fine. I also tried another scaler (rock+) and the problem was the same. Any ideas anyone?
Thanks
Colin

Colin have you tried swapping the RGB cables to see if the trouble follows ?

Yes, the problem stays on green.

I had a problem like this on my 701 the image was very pink....I think I fixed it by switching the port, from 5 to 3 (or it could be the other way round)

Are the internal menus/test pattern weak on green as well?

Internal menus are fine. I haven't tried port 3 as I lack a suitable cable. I will make one so I can give it a try. However, the port 4/5 configuration used to work with a scaled input so something has gone wrong somewhere.

OK, if the menus are fine, then I'd suspect the RGB Switcher board. I can repair yours. Is this a Graphics or a Data 808s?

Also, try the video and Svideo inputs with a video source. I'll bet those will be fine.
