I had the same problem, and my machine has no G2 adjustment so I could not use that to adjust the brightness as ecrabb mentions in this thread. Here is what I did after turning akb off:

I then raised the BIAS of the lit tube until it's level was equal to black. After repeating the procedure for all 3 tubes I turned them all back on and what do you know, the gray scale looked really close. I put in a movie and it looked great, plus my brightness control is no longer maxed so I have some range to play with.  The bias adjustments were pretty big, (started in the 70's and ended up in the 200's) but fortunately there was enough range to get me there. Hopefully there are no unforeseen issues with running the values this high, but as it stands I now have a picture I like and flicker free 1080p! |
