1986 RCA Console TV Model G25343WK

The parameter for each would stay at 0. I’m thinking blue is caused from weak CRT. Blue really flames outward around lettering etc. when TV is set back to original setting of the blue drive & leaving picture level at factory setting. No luck of eliminating excess blue color in some pictures even with picture, bright, & color tweaked way down. The only way to get it as good as I can is leave blue drive & bias down which in turn gives a somewhat greenish cast to white.

The best way to be sure is put on a nice bright picture source and put it in freeze frame. Then mark or otherwise note the blue flare. With a still picture, nothing should move. If the flaring tracks with the contrast setting, the tube is the culprit. If the flaring is static while the contrast is moved, something else is going on.

The blue flares some if you freeze the picture. It helps picture quality & look some if I move tint more towards a Green. The way it’s currently set at Red looks a little more like magenta. The greener tint takes away some of the blue shadowing.
