LG Projection TV Model# RT-49NA11T Green color gun shows bent arc on top & bottom.Red & blue guns are ok.How to adjust the green gun to remove the bent arc. This is causing picture shows mix color bars on top & bottom of screen.I blocked each gun at atime & found that green color gun is the only one which is showing bent lines on top & bottom. Please advise how to adjust & where is the adjustment on green color gun?
