Hi all,

I had a RCA PFR 100 projection tv handed to me.

All three CRT's power up but then the Blue and green shut down and no
video can be seen even on the red crt.

When switched to "Aux" video input, without a signal I get all three
CRT's to power up but the moment I feed it a video signal the Blue and
green CRT's shut down.

Anyone have any suggestions or a schematic for this TV?

Thanks
Jay

I did some more poking around, and looks like I see the retrace from
the Red CRT and ocassionally the blue and green, but very blurry,
anyone have any ideas?

Thanks

What chassis is in the beast?
It is way too old for our information, so need chassis to help.

CTC132 variant?

I am looking at the chassis it says VP1 on it. Sam's photofacts seems
to carry this so I will check with my local library maybe they can find
me a copy.

I played around a bit more with the TV, The main problem seems to be
the Red CRT tube staying on all the time, I can see the retracelines
from the Red CRT so maybe I need to focus on that. I can make out faint
outlines on the projection screen if I increase the intensity of the
blue and red crt's but the red still drowns out the other colors. Maybe
the shutdown of the Blue and Green is a side effect of the Red staying
constantly on.

Thanks
Jay

Well no luck at the local libraries, based on some more reading I am
doing sounds like I have a red oversaturation problem?
