> slightly distored and has many horizontal lines. As
> set warms up frequency rises. once it goes out of
> human hearing range the picture cleans up hor. lines
> disapear and everything is perfect. Have tried using
> freeze on horizontal linearity coil and on the
> hor.driver transformer. Pretty much tried freeze on
> all sectors trying to reproduce problem but problem
> only happens when tv is off for a period of time.
