Horizontal Bar
 

My RCA TV (which is quite old) recently started to act up. When you
first power it on everything is fine, but after a short time the
screen shrinks to a single horizontal bar at the center of the screen.
This will not go away even if you turn the power of and then back on
unless you leave it off for hours at a time.
I would really like to be able to fix this if anyone has any ideas.

There are components, especially electrolytic capacitors in the vertical
circuit area that have become thermo sensitive. I usually find these using
freeze spray and a heat gun. After locating the ones that react to
temperature shift, I replace them. If any parts fail permanently, then more
complex troubleshooting will be require to service the set.

Please give us a chasis # (usually starts with CTC then a number),
that way you
may get intelligent help. Since you said you had an OLD RCA TV try
replacing the 6CG7
vertical oscillator tube.
