the TV.

This may be a failure in the tuner, or there is a problem with the
AGC.

Bring the set in for an estimate if you want to have it properly
serviced.

Considering the age of the set, I would think more so it is time for
a new
one!
what gives? is this a tube problem or is it something else?
thanks.
