The complaint on this set was intermittent vertical. I have not been
able to get the set to fail however I noticed at least three burned
resistors, around the vertical section. Two of these are near the
vertical yoke wires and are mounted conventionally. They have hot melt
glue slobbered all over them. The other is mounted diagonally. I'm
relating this because I am unable to read any identifying marks on the
chassis for any of these. I know that there were alot of vertical
problems with the 169 and I was wondering if anyone had a copy of the
manual for this set that they might be able to share with me. If I
could see a board layout as well as the schematic of course it would be
of tremendous help in identifying the parts and troubleshooting the
circuit. If you do have the manual and are able to send it, this email
address will not accept it. Please send it to:

Thanks very much for any assistance. Lenny Stein, Barlen Electronics.

"I know that there were alot of vertical

You know what, in the hundreds of ctc169s that were fixed some time
ago, I only ever ran into ONE vertical circuit problem ever.

eservice web site has a ctc169 basic chassis information and schemtics
program available for download.

That pretty much duplicates my experience. I'd consider it to be a standout
for NOT having vertical problems, at least IME.

I do remember the single ctc169 vertical circuit problem I had was a
real dog to find the culprit. If my fading memory is still good, I
think it was a leaky diode in the vertical circuit.

I checked eservice but there is no 169 manual available on there. Does
anyone have a copy of the manual so that I can identify these componet
locations? RCA boards are so difficult to read component lettering off,
especially when they're covered with glue. Thanks, Lenny.

Hi David
I did find the information and thank you for pointing me to that site.
It will be very helpful in the future I'm sure. I also obtained a copy
of the Sams for a 169 however for some reason it does not show a
component side detail of all the components with locators pointing to
them as I am accustomed to seeing them on Sams. And just when I really
need that too! If you or anyone else is more familiar than I am with
parts placement on this chassis could you please take a look at the
links I have included? Maybe we can identify these resistors and I can
try replacing them. I have found some cold solder joints around the
yoke connections and perhaps this is what caused the resistors to burn
in the first place. I just can't seem to read the markings on the board
for these parts.
The first picture shows the entire board section involved. In the
center of the picture between the violet and grey yoke wires is an
obvious burned part. Down on the lower right are two more resistors
mounted diagonally to most others on this board. They show some white
in the middle as though they have also been overheated. Then picture 4
shows another resistor just to the left of the grey wire (whos lead is
just visible on the first picture), burned as well. Thanks once again.
Lenny Stein, Barlen Electronics.

I´m not an expert, so please take this with a bit of salt. From the
pictures you posted, seems to me that the first resistor is a 100 ohm
flameproof resistor. I can see clearly the rennants of bands brown,
black, brown and gold in that one. By the size you can judge if it´s
1/2W or 3/4W (I can´t determine that from here)

I am not sure about the second resistor. I can see orange, white... but
I´m not sure about the third band, it seems like black to me. Since
this resistor is not completely burnt, you should be able to unsolder
it and check the underside of the resistor. Maybe the third band is
intact there.

Good luck.
