Red & green shadowing on the right side of picture


First thing to try is a convergence but with the red shadowing seems to me that you may have your color gun going. Convergence can be found in your video menu on your setup screen. Once in the menu you can adjust the colors to line up. This usually has to be done on a tv that has been moved.

Red color convergence issue; Red lines are curved


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

You have a projection light element out. I had the green element go on mine. I had a service agreement so a repair tech changed it.

Pictue is dark as hell


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
