Question about Sharp 56DR650 56" Rear Projection HDTV
That would be either a bad IC (integrated circuit) chip or loose or bad solder joints on the circuit. You can google ic circuits to see what they look like. If you feel the need to test it, they do sell analog tester fairly reasonably priced to test them, but that is usually what causes the lines, especially if the are horizontal lines.
