1993 RCA 27 Inch Console Set

[Console User]

Does anyone know if the following Chassis CTC169CA2 was known to have any issues on this era of TV Set? I know, that some of my other RCA Sets have had issues with the solder connections in the Tuner Board?

Thanks.

Electrolytic caps in the power supply. Can cause B+ to rise and take out other parts. Some suppliers used to offer a "kit" of all the parts necessary to repair this issue. Remember a 15 mfd cap being very critical.

IMHO that chassis was RCA's best. Always had a great pix when done.
Never junked one.
Add to the common list IIRC CR4118. Its an 18V rectifier off the
switching transf. Causes very subtle intermitant color & video
probs. It was a change in every repair part. Also one or two
'had the same P## so those got changed too. Should be still around as RCA NOS.

The CTC169 was the best RCA chassis from the Thomson era and I loved working on them. With most of them, it was the electrolytic capacitors in the power supply that would fail, causing B+ to rise and eventually blow the HOT, and these caps would sometimes take out the chopper transistor and driver IC. There was also a big blue cap in the HOT collector circuit that would open. I rarely ever encountered a bad flyback in a 169 and the chassis was used in everything from 27" all the way up to projection sets.

One thing to take note of is you must use exact replacement parts because generics or substitutes won't hold up. In the late '90s-early 2000s, there was a TV shop in town that used to give me all of his "rejects." This shop wasn't very good and he hated 169 sets, saying that they never stayed fixed and always came back to bite him in the butt. As it turns out, he was pulling HOTs off of whatever random TV board he could put his hand on the quickest and I warned him about that. I told him that since he hated them so much, I'd take any and all that he wanted to give me.

That chassis had a long production run, from about 1989 until the late '90s.
