Has anyone seen this chassis ?

It's labeled 25" RCA CGA KT-2.

Picture is super dark and constantly loses H-Hold.

I haven't dug into it yet, I was hoping to find a schematic.

Thanks,

John

Did you turn up the screen pot when It was hooked up.

was it all the way up and still not bright?

I would suspect the caps.

remove old ones copy the location and values.

post the caps and location.

and we can build a cap kit for your chassis.

What have you found out so far?
 
I dug into it last night. I changed all the caps on the
main board. The first 3 I pulled were way, way bad. A
bunch were "ok, but I don't think they'll stay ok for long".

Surprisingly all of the high voltage caps were good.

The board has some weird hacks. I don't know if it's original
or a repair. There are two 100uf@200v caps, one in the
holes of the board and a second glued to the side of the first
and jumpered to a coil and jumper on the board so the 100uf
is now 200uf.

I didn't get to the neck board yet. Since I didn't have a schematic and
never saw one of these I took my time.

I will finish the neck board this week as well as test a few suspect power
resistors and probably try the chassis on Saturday.

I will post my results.
