Hi there
I've got some problems setting up the G2 on my Barco Graphics 808 (non s) The unit is original, 1996, 3500 hrs.
1. When adjusting G2 from within the service menu, i can only turn the G2 led's off for the green and red tube. I can not get the led on the blue tube output board to turn off. No matter how slow i turn the blue G2 pot, it just won't work. So i set the blue G2 by hand, approx. at the same level the green and red are at.
2. After doing the above setup, the picture has a big red push. When switching scenes, e.g. pluge to 0 IRE black and vice versa, the picture is red initially, and after 1 or 2 seconds it fades out to black again. If i turn the red G2 back a bit so the black image is black again, the red push is gone and everything seems to be normal. (ABL circuit ???)
Are above 2 problems related ? What could be wrong, and how serious is it ? Like i said, if i turn the red G2 back a bit everything is nice. Good image, deep blacks etc. I surely could live with this setting, but it does worry me a bit. I don't want to ruin my 808... O yeah the output boards for all 3 guns are tested and calibrated and working fine.
