Yep. The Dimensia was a tarted up ColorTrak 2000. I believe the software was the difference. The Dimensia also had a black RCA connector on the back that matched up with the Dimensia audio components. You could program the TV to come on at a certain time, turn on the audio components, and even have the cassette deck start recording.
There was a demo mode to that bad boy as well, something quite unusual for the 80s. I can't remember the key combination to push though.. Give me a day or so to think about that.
Anyway, the CTC140 was probably the best analogue TV ever built from a picture standpoint, better than any variation of the 169 that replaced it (and there were some excellent 169s).
Whereas the later 169s came in low end versions, all of the 140s were fabulous performers. They even made a 20" version. I can't think of any CRT TV that had the combination of detail, sharpness, smoothness, and lack of artifacts than the 140 had.
The 140 was not trouble free however. The good news is that you won't need what I call "hard parts" (transmission term) like flybacks, yokes, drive transformers etc.
Almost every 140 has connection issues on the small daughter board mounted upright behind the SMPS transformer. There is a thin air coil inductor and three rectifiers on that board, and the solder cracks causing intermittent shutdown and restart. If you get a spontaneous restart, look there first.
There are some other issues that we won't talk about now. If that is a low hour TV, you probably will only deal with the daughter board solder connections (we had to solder them even in warranty).
Enjoy.
