Wavy Vertical Line

Out of the blue a wavy black line has appeared to the left side of my monitor screen. It appears at the top and bottom but does not connect. It looks like a worm. I thought maybe it was some kind of worm and did my normal scanning and it is still here. Nothing was found in my AVG virus scan. I have restarted my computer several times but the line is still here. HELP!

Wavy horizontal lines across the screen


It sounds that the main power supply section to your TV has the fault. The horizontal thik lines that appears crawling down across the screen should be of video 'HUM'. Have you replaced the main filter capacitor at the power supply section? If not, replace it along with the main rectifier. The AC power is rectifed by a bridge and applied ot this main filter capcitor. It will have a capacitance value between 120 to 350MFD 450VDC. Check this section. Measure the rectifed DC voltage acorss this main filter capacitor. It should be around 350VDC, if your home power supply line is 220VAC. If it is 110AC, this DC voltage will be around 165VDC; and it should be. If rectified DC voltage found lower than the input AC voltage, replace the rectifier bridge. In some sets, this bridge section have four diodes. Some other circuits, a bridge rectifier stalk may be used.

Shadows on screen


Try moving a medium powered magnet (not one for picking up heavy objects and not a refrigerator holding one) over the distorted area. If that doesn't work, try a more powerful one. This worked for my Toshiba LCD. Good luck!

Lines on tv screen


Both sound like bad LCD panels. The following must be answered to confirm this:
Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad
