1986 RCA Color Trax TV

[Console User]

I have a 1986 RCA Color Trax Console TV. I bought it about 3 years ago from a Gentlemen whose Mother had passed away. I had it in a Repair Shop sometime after I purchased. The Tech. replaced some bad capacitors and soldered some bad connections. It has the CT 120 Chasis in it. The Model # is GLR689PR. I have never been able to turn the color up much as when you do the Blue Color Bleeds. Also, can't turn the Brightness up much compared to other Sets I have as the same problem occurs. All in all the picture isn't that bad, but just not as outstanding as some of my other sets.

The CRT# in it is a A63 ABP13X. Is this problem a sign of my CRT getting weak or was this a problem with this particular Set?
