There were 6 knobs on the inside of the tv 1 screen and 1 focus for green, blue, red. I adjusted down the screen settings for the green and the blue and that made all the difference in the world, there was a bit of a red tinge to the picture especially on the left side of the screen (the side with the red lamp) I adjusted down the red screen setting just a hair, and that seemed to help as well. My question is first off am I on the right track by adjusting these settings or am I just messing things up. Also do I need to adjust the focus on these lamps after I get the screen settings set?
Thanks

YIKES!!! Stop!!!
Don't touch those knobs further, especially the "screen" ones.
In fiddling w/ them, you just might've ruined the color balance (ie. grayscale) of the display (not that its grayscale setting was likely ever great).
If you can afford an ISF calibration, I would suggest hiring a good ISF certified tech to give your new RPTV a good tune-up, especially since it sounds like the settings could now be in very bad shape. If not, you need to at least get a good calibration disc -- try the Digital Video Essentials (or maybe AVIA, if you don't have HD sources) -- and learn to (carefully) do as much of the calibration work as possible.
If you've never done any of this stuff before, you've got a lot to learn -- and in the end, you're probably best off paying for the ISF tune-up instead.

Re: Contrast Issues
Yes, turn the screen pots/knobs back to the previously marked points and then check to see if your grayscale looks ok. If you don't have a dedicated calibration disc, you can at least try one of the THX Optimizers found on certain DVD titles (eg. many Pixar ones have that) to help you out some. That should at least help you get back to a reasonable ballpark.
I'm not familiar w/ the RCA RPTVs, but I'd think there should be some setting in the service menu for what you want to do (unless something is actually wrong w/ your set). One of the friendly ISF folks who frequent here, eg. Gregg Loewen or Michael TLV, will probably know and might be able to help you w/ that. You should also try looking for a service manual for your RPTV before you do that.
