Halo around main subject

it could be lcd screen

Use the largest screen to get a better idea of the focus. Smaller screens lack the resolution to show a slightly unfocused shot - but it will be noticeable later when printed or viewed on a large screen. Of course, these screens eat battery life - so you can use your optical viewfinder whenever possible.

Question : Why are my pictures out of focus (blurry)? Answer : This problem can occur for one or more reasons. Here are some common causes and suggested solutions.

• The lens is dirty. Use a soft brush to remove dust and dirt. Wipe the lens gently with a soft, lint-free cloth or an untreated lens-cleaning tissue. Do not use cleaning solution unless it is designed specifically for camera lenses.
• The subject was too close to the camera. Make sure that you are far enough away from your subject. Each camera has a recommended distance for normal, telephoto (zoom), wide-angle, and close-up pictures.
• The subject was not within the effective range of the flash. Each camera has an effective flash range.
• The camera did not focus or expose the picture correctly. For the best possible pictures, press the shutter button halfway and hold. When the Ready light or framing marks turn green, press the shutter button completely down to take the picture.
• The LCD screen Preview feature was not used to take a picture in Close-Up mode. Always use the Preview feature in Close-Up mode to confirm focus and to frame the subject properly. If the Preview feature is not used, the LCD will not display an accurate view of the subject.
• The subject or camera moved. Hold the camera very steady when taking a picture, or place the camera on a flat, stable surface. You may want to consider using a tripod or monopod.

This is a common problem. Its called a convergence failure.

it sound's like have a convergence problem send me d model and make of d tv

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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 a convergenece repair kit with instructions from the links below.
