Have some service settings questions for my kv-30hs420....

I have a 30inch widescreen kv-30hs420 crt and in the service menu what is the VCPO setting do inside the MID3? When I adjust past 63 it makes the color darker and darker and darker......

Also couple items below or above the VCPO, theres the VSTP that adjusts the bottom edge angle, which I adjusted fine, but the top of the screen needs to more straighter but I have the either the VSTT or VYCD all the way down to ZERO but its still not straight. Anyone know what to do? THanks...

I wonder if UCP setting in the "CXA2170D-2" will fix that? Or how about the YBWU?

Also another question I forgot, I notice that when something is like a dark color like red, orange, it has that effect where the color bleeds on the edges of whatever the object your looking at. Kind of like when your adjusting something in the standard settings like color, tint not sure what one but the colors will bleed and glow more. Anyone know what service settings fixes this?

Have you used a calibration disc like Avia or Video essentials? If not I would seriously recommend it. It will answer all of your questions, help you get the best possible picture from your TV and tell you to not use those settings or to turn those features off as they only add artificial information to the picture that was not there to begin with.
