Blurry, purple bar across middle of plasma tv screen


Plasma screens are extremely susceptible to getting broken from any impacts to the face of the screen. What you are describing sound very much like distorted or dead pixels. It may not be a fixable issue, you may have to replace the entire unit or live with the purple bar. The reason you don't notice it as much when the screen is dark is because purple is on the darker end of the spectrum, and will be most visible in contrast to lighter ad brighter colors.

Screen Resolution


Click the "Start" menu. Click "Settings" and "Control Panel."


Choose "Display" and "Settings" in Windows 98, ME or XP. In Windows Vista, click "Appearance" and "Adjust Screen Resolution."


Click on the resolution bar and slide it to the right to lower the screen's resolution and to the left to raise the screen's resolution.


The optimum screen resolution usually depends on the size of the laptop screen.


The recommended resolution for a 15-inch screen is 1024 x 768, 17- to 19-inch screen is 1280 x 1024, and 20-inch screens is 1600 x 1200.


However, you can adjust the resolution to your personal preference.


Click ""Apply to see how the resolution looks on the laptop's monitor.

Click the "Start" menu. Click "Settings" and "Control Panel."

Choose "Display" and "Settings" in Windows 98, ME or XP.


In Windows Vista, click "Appearance" and "Adjust Screen Resolution."

Click "Colors." Choose 32-bit for a high color-pixel ratio that will make the colors brighter and bring out image details.


Choose 24-bit for a medium color-pixel ratio if the screen is too bright or if images are somewhat distorted.


Some older laptops have a 16-bit color setting, but this setting is no longer recommended as it will distort images and text.


Always Click "Apply" to see how the color setting looks on the laptop's monitor.

Click "OK" to save the color settings

My Olympus x-42 doesn't take a picture. View from monitor is perfect but when I take a picture, all there is is a white screen


Some symptoms of a defective CCD (Charge Coupled Device) include distorted images or abnormal colors, scratchy purple lines, blank or black pictures, and/or black videos with good sound being recorded on the camera's flash card.

When a picture is taken, the CCD is struck by light coming through the camera's lens. Each of the thousands or millions of tiny pixels that make up the CCD convert this light into electrons. The number of electrons, usually described as the pixel's accumulated charge, is measured, then converted to a digital value.
