Glenn:
Bad solder connections on and around vertical output chip circuitry and/or
faulty chip or other related parts.... diodes, resistors, high ESR
electrolytics, etc. Standard testing and troubleshooting procedures will
diagnose this specifically.
You may want to go to the website for this newsgroup at
http://www.repairfaq.org
there with some searching you will find helpful information ... or
TAKE it to a repair shop for at the very least a repair cost estimate so you
can make an intelligent repair decision with facts instead of internet or
telephone wild guesses. This is usually a very economical and
straightforward repair at most shops.

I have an RCA ColorTrak 2000 TV that is about 15 years old. I suddenly
lost
the picture. All I get is a horizontal line in the exact center of the
screen about 1/4 inch in height.

Suggestions on repair?
