RCA Dimensia 26" TV help!

[zenith2134]

Having owned a number of RCA Dimensia 25 inchers, I think they were a fine set of their era. That being said, the previous gen with the CTC-121 chassis (Lyceum) had a better pic on it to my eyes. I once read that those used proper I-Q color demod like an early color set would use.

My last remaining 26" RCA is not as sharp as it once was but, in its defense, it was used when I got it and has never had the back off. It's the MTS stereo model with OSD from 1987.
