RCA (Thomson) may well have gotten the bugs (most of them, anyway) out of these sets by the late 1990s, and certainly by the time the CTC203 chassis came out (RCA had begun mounting the RF tuner remotely from the chassis by then). I have a CTC-185 table model that still works as well as it worked the day I bought it, almost 16 years ago. I had a couple of repairs done on it for an antenna connector breaking off the tuner PC board, but other than that the set hasn't given me one bit of trouble. I put it in storage (along with my Zenith Sentry 2 19" table set) when I bought a flat screen in 2011, but the last time I plugged the RCA in and switched it on, it worked--well, at least I got a raster, snow and the OSD operated as it should.
One other thing the technician who resoldered the antenna connector the second time did was also to resolder the ground points around the tuner shield, but that was the only time I had the TV serviced. No problems since then.
These sets (CTC-185, et al. until the CTC203) were known for their problems with the EEPROM chip, which would be destroyed when noise got into it as a result of poorly soldered grounds at the tuner shield. How my set escaped this problem is beyond me,
but I'm glad I had no problems with it from that source or from anything else. I'd still be using that RCA today if the TV transmission standards hadn't changed six years ago. The CRT is still as strong as ever, which surprises me since I used that set quite a bit until replacing it with my current flat screen.
