Question about Sylvania 6427FF TV
I am having a problem with my Tv. It seems to display wavy verticle lines at the top of the screen. I have no idea what is causing this.When i access the service mode and If i make a change to the horizontal freq. The problem is reduced significantly but it seems to come and go every few seconds. I checked the board for loose connections and I found only 1 and after repairing this it still seems to show wavy lines at the top of the screen . I need some help! thanks.
I would suspect defective filter capacitors in the sweep circuits as well as the power supply source voltages.
