Last night the kids put on one of their DVD's..."School House Rock", which when I looked at the tv had a VERY BLUE tinge throughout the entire picture. My heart started racing....I thought something had happened to the tv...or the kids had touched something they shouldn't have. I turned the set off...and then back on again, but no difference. Everything seemed ok in the picture settings......what the hell was causing this blue tinge??? Well....soon I discovered the problem. The night before, I had been playing around with my PC, which I had connected to the front of my Panasonic Viera (TH42PV30). I had decided to try and use my laptop PC as the dvd player to see if it was any better than my Pioneer DV-344. Usinig DVE I played around with the PC menu on the TV....which is of course a very different menu system to what is used for AV inputs. It has the little menu box that appears in the top right hand corner of the screen, which has options similar to my AV picture settings menu, but has alot more options such as Gamma control, Red and Blue cuts and gains adjustments, size and position (All of which I believe should be available in the standard AV picture menu). Anyway to get to the point, I had ended up cranking the B-Cut settings to +9 in the PC menu in order to get a very nice looking greyscale using the laptop as the dvd player. Here's where it gets interesting...........DID YOU KNOW that the PC settings for White/Balance have an effect on your regular AV inputs as well!!!!!!! I couldn't believe it......spent $300 to get my v calibrated...going in and out of service menu blah blah blah....only to find that you could easily screw the whole thing up by changing the blue and red adjustments in the PC menu........ So in the end, I normalised all the PC menu settings and then went back to AV2 (DVD player) to continue watching Scool of Rock....and as one would guess....all the blue tinge is gone. WHAT A JOKE!!!!!!
