Look up the information in the repairfaq for the ctc177 series
chassis.
It is highly unlikley you have the equipment available or experience
working on surface mount tuned rf circuits to do any kind of repair
inside the tuner.

It is not a replaceable part, but gets repaired to the component level
and requires extreme care, lots of experience to avoid further damage.
I would definitely recommend taking the tv into someone with lots of
experience on that series of chassis that has all the reuqired
equipment (including a 125 channel cable tv tuner signal generator).
Worst case repair should still be under $120 total parts and labor,
typical average $80-90.

My RCA TV appears to have "lost" some channels.

Most channels are OK. Cable Channels 48, 49, 50 are wiped out.
Channel 65/66 experiences intereference from over the air channel 14..
Other channels that I know I should get seem to be ok, including those
that might be effected by other OTA channels. RCA input video is ok
so I surmise it's an RF problem.

Here is the RF section:

Is there a way to open it, service it, replace (guess I could desolder
it), tune it, etc?

Thanks!
