    I actually had an altec lansing w/ besides the LCD monitor but left and right satellite speakers but its said to the instructions manual of the speaker, it is okay to place the satellite speakers nearby the LCD monitor because its magnetic shielded only the subwoofer is not recommended to place near to monitor.

    Is it my LCD monitor Damage? what if i never place anything on the top of the table only the monitor alone..what if the problem is there again?

    I actually try to touch the back of the LCD monitor when the problem is there....and it seems sometimes its cannot easily be seen in one time only you have closely look it to see it.

    Help me..I want to know wheres the problem going on...pls help.......Thanks again...

The interference may be another electrical item, for example a tv or speakers, turn off anything close to the monitor and check that there are no bent pins in the pc to monitor VGA cable and that it is not interfering with any electrical cables to see if the problem is illiminated.

I have been dealing with this same problem for a month...I just now unplugged my speakers completely from my computer, and the problem disappeared. Thank you, thank you, thank you, this has been driving me crazy....I guess I'll buy some new speakers.

I'm having the same problem. It's odd as I had an Acer AL2216W hooked up to a custom build PC (Intel DG965OT with onboard video) and after a switched to a Toshiba Tekbright 22", I started seeing these wavy lines. However, when I hook up my old Gateway 450ROG to the Toshiba monitor, the lines go away.

My guess is that it is a video card to monitor issue (at the driver level or a hardware minor incompatibility). Eventually, I'll upgrade the video card to see if this eliminates the problem. Currently, it's not severe but if it worsens, I'll test that hypothesis.

I had the same problem and went to the monitor settings and changed the refresh rate from 60Hz to 75H. The lines disappeared!

When i had vertical bright waves in my monitor, i found that it was the power pack to my laptop that was causing the waves. after i unplugged it the waves went away. I tested this several times to confirm it was not a coincidence.

Power packs may have a strong EMF as they are generally small transformers.

Actually those wavey lines can also be caused by a noisy AC Plug...try unplugging your monitor from the plug and try the plug below it, or if your using a powersurge, try putting the powersurge bar into another socket nearby and see if you get the same results. The other solution is if you're good with electricty and know how to repair noisy outlets then you can solve the problem. Or be daring and find a tutorial online lol

It's the same problem I have in my new purchased second hand unit theres a wavy lines showing running all around vertically and I found out it's not an interference by any electrical devices but a hardware failure...

As the product is under a year old it should be covered under warranty. Get in touch with asus customer services before you let anyone attempt a repair as doing so may invalidate your warranty

Colored vertical lines on monitor

Have you unplugged the power cord to the LCD? Let it sit for a minute, then try it. ALWAYS buy a UPS and plug any computer devices into it. Doesn't have to be big, a $50 unit will protect it from dangerous voltage surges.

Sceptre X20G Naga III showing horizontal and vertical lines


Yeah, there it... It's called a AD board. It that piece of component were you plugged your VGA or DVI cables to it. Panel scratchs repair kits, not recommended. Beside your panel could be already damaged by this problems you had. Replacing the AD board gonna cost you though...any where from $70.00 or more... My recommendation, just get a new one...saved you the headached and $$$.
Have a nice day!
