RCA/Thomson did have a lot of trouble with the onboard tuner in the CTC-17x-18x series chassis (as you probably knew if you were working for RCA in the '90s), but once they changed the design to separate the tuner from the main PC board, the sets became more reliable. Unfortunately, that change did not happen until the CTC203 chassis. (My RCA CTC185 did not give one bit of trouble, from that source or any other, except for a loose antenna port that snapped off the tuner PC board, from the time I bought it in late 1999 until I got a flat screen 12 years later; who knows, maybe I was just incredibly lucky, considering all the trouble that onboard tuner was -- and the callbacks it generated -- for RCA in the '90s.)

I don't know how the tuners in today's "RCA" branded flat screens are mounted, but I hope they didn't go back to the onboard design. The problems the onboard tuners in RCA's CRT sets caused should have sent a loud and clear message to RCA's R&D (research and development) department never again to use that design in future sets from the CTC203 going forward.

BTW, "Ctc-1" (the title of your post)? I didn't know RCA even made a CTC-1 chassis; I was always under the impression that their chassis numbering system started with CTC2, then CTC2a, CTC2b and so forth. I don't remember ever seeing or hearing of an RCA CTC-3 chassis, either.
