How do I fix wavy lines on Hauppauge Wintv hvr950q?

Are they wavy lines throughout the picture or are they just wavy on the side? Waving picture is usually caused by poor power supply filtering. Wavy lines throughout the picture are caused by interference. Try moving the device away from the computer with an extension USB cable it may be picking up interference from the surrounding electronic devices. It could also be defective.

Sylvania 6427FF TV displays wavy verticle lines at top of the screen.

I would suspect defective filter capacitors in the sweep circuits as well as the power supply source voltages.
