I have a 1986 RCA Colortrak 2000 27 inch console television (I believe the chassis is CTC133B if I'm reading the correct label) that I got for free that has a really nice picture with one exception.
There is some warping/arcing/curvature of the image, which can best be seen when watching a letterboxed image. I've made a diagram which I hope illustrates the problem. Please see:
Any ideas what the problem might be? Since it has a nice picture I'd like to see what I can do with it. Ultimately I can live with it, but if it's not too difficult and/or expensive I'd like to fix it.
Thank you in advance.
