It's possible your video card or monitor is going bad. Which type of monitor do you have? If it's a CRT then my guess is....monitor.
Check all your cables and connections first.
If possible hook up a known working monitor to rule out memory or video card problems.Monitors have a refresh rate but I don't
recommend doing this without supervision or complete knowledge.
Check to make sure you don't have any interference close to your monitor. Interference would/could be: magnets/speakers/radio's/televisions/microwaves (not sure about micros.
If your have a LCD monitor I'm not sure all these suggestions apply.

Phillips 28in wide screen tv. Picture OK through Sky, but has two moving distortions on ordinary aerial. Actual picture is good but the distortions moving up the screen make it very difficult to watch.

Even digital signals can be sensitive to electrical interference and using an antenna, you could be getting garbage from any nearby 'noisy' source. Something you might try is to temporarily switch off any electrical device in your home, one at a time and look for changes in the banding you have.
If the antenna you are using is outside (rooftop) and is rotor equipped, try changing the position to see if there is any increase or decrease of the problem. If an indoor antenna, rotate it slowly while watching the TV display for change. You may be able to determine the general direction of the source of interference. Some seemingly innocent devices that can cause problems; - Light dimmers/controllers - Poorly designed network routers - Cordless phones - Power supplies

Kv-35xbr48 turns on fine nice picture then horizontal lines form distorting picture like interference also is the back hard to take off and put on needs a good vacum thanks for any suggestion

At first the picture is ok, and then distorted with horizontal lines i thinks. If the horzontal lines are parellel acros the screen, with an inch apart across the whole screen, your tv needs screen adjustments. Screen voltage may be high. look into the crt base also. Change it first. These also not resolve the problem, LOT may be faulty, with respect to screen focus pack. May need replacement. Try first setting screen voltage to a lower settings and observe.

Have Samsung HLN567W and recently started having

Projection TV sets have two very common problems listed below.

Problem #1) Convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

22" Acer flat screen monitor


this sounds like an electrical fault or failing component, within the Monitor.

Check the cabling, to ensure it,s not damaged-broken-kinked et,c. by carefully moving the cable gently side to side and up and down.
If it puts itself right for a second or two. you can assume its a broken internal wire, within the lead.
Or a dry soldered joint-Connection.

Monitor distortion

Hey edwardaaron,

If you are encountering any kind of visible distortion on your computer monitor, there are a couple of things that I would suggest.

First, if you have a cathode ray tube (CRT) monitor, you may want to try manually degaussing the monitor. Whenever a CRT monitor is in use, it slowly builds up a magnetic charge that can interfere with its operation. Degaussing then, is the process by which CRT devices rid themselves of this excess magnetic charge. This is normally done whenever a monitor is first turned on, but many monitors will also have either a button on the front control panel you can press or an option in the main menu to perform a manual degauss.

In many cases, the degauss option will be marked with a horseshoe or magnet-shaped picture. Once you've selected this function, you may notice a metallic-sounding "twang" noise, followed by one or two "clicking" noises as the image on the screen is reset. Keep in mind that images on the screen may appear to vibrate and color may distort for a few seconds after you do so, but this is a normal part of the degaussing process. The screen should return to normal after a few seconds.

Second, interference can also be caused by placing your computer speakers too close to the monitor. Many speakers will produce a magnetic field of their own, which only adds to the magnetic field generated by your monitor. In this case, repositioning your computer speakers should help minimize the problem.

If degaussing fails (or you don't have a CRT monitor), you may wish to then test the cable connections to your computer. In some instances, simply replacing your monitor cable will resolve these types of problems.

You may also be encountering a problem where your monitor is simply set on the incorrect refresh rate. If the refresh rate is not correctly set, a monitor may display a "wavy" image or appear as if lines are periodically scrolling across the screen. Without knowing the exact make and model of your monitor however, I would not be able to provide any suggestions on how to change this setting - you would need to contact the manufacturer or refer to your owner's manual for specific instructions.

The worst case scenario would be if you are encountering an actual hardware failure. Both the video card and monitor can cause images to be distorted if they are not functioning properly, and even power supplies have been known to cause other components to sporadically malfunction. If you are unsure how to perform a hardware diagnostic, I would strongly suggest speaking with your local computer repair technician or a Geek Squad® agent at your local Best Buy™ store for further assistance.

Hope this helps you out.

Go Ahead. Use Us.

Screen Distortion at certain Refresh Rates

Have you connected the laptop to another monitor and use the same refresh rates that cause the distortion? If the distortion appears on a different monitor, then I would have your laptop examined by a pc engineer, but, if the distortion only appears on the 997DF monitor, I suggest having the monitor checked at a repair shop, also, have you tried connecting the 997DF to a desktop PC, and use the same refresh rates?
