Today I made my annual adjusting to my Barco 708. At this time, I though to go through also G2's with optical and beam focus. I tried the LED method with adjusting menu. Doesn't work as it should be. LED goes on and off and it seems that pots are not working as they should be. I even managed to turn off the green's LED while blue's LED start to illuminate from the same pot Also entering to the G2 menu back and forth affects to LED's. So I tried the basic G2 adjusting method. Set contrast = 0, brightness = 50, 6500K and AVIA with IRE 0 pattern. When raster just fades away, the G2 is correct for the tube. Am I correct? Black details are okay after this adjustment and picture is also bright enough. When entering to the G2 menu, all of the LED's are illuminating? Should I be worry about this? Am I driving my tubes dead?
