Camera

[Leroy Eckert]

Thanks Bob:
I think mine is called a concentric potentiometer, I am not certain, it appears
to be a sealed version, has two dials one on top of the other similar to the old
volume, bass controls on a car radio and it says it is 100/500K. I think it has
6 small wires. It is used for contrast and brightness on the tube. I went to
the web on a guitar site and see some similar but the ratings are different.
Then I have to do something with the knobs. Thanks in advance for your help.

Sorry, I hit the wrong "thingie"

Leroy,
Since you do have a good picture when it is
working you might try replacing the potentiometer
if it is the one overhead apart from the TV.

Pot is an abreviation for the word potentiometer.
3 terminals, one in the center is a wiper and
gets a glaze from use. Sometimes a spray into the
opening will clear it up.

Two major concerns on replacement are resistance
value and wattage, along with shaft configuration.
Disconnected, measure the resistance between the
outer terminals, this will determine resistance value.
Physical size will determine wattage. Even if the
part number doesn't match you can replace from an
electronics shop of the web.
