Hello
You can set the picture size by remote control itself.

You can vide 480i format programmes in three picture sizes. 4:3, 16:9, and ZOOM
You can change the picture size by pressing the PICTURE SIZE button on the remote control.
4:3 Picutre size
To fill the screen, the top and bottom edges are extedted more widely, although the center of the picture remains near the former ratio.
If receiving a 4:3 programme, the image size is displayed in its originally formatted proportion.
16:9 picure size
This image displays the size of standard 16:9 with black bars at the top and bottom.
If receiving a 4:3 programme, the image is displayed with black bars at the top and bottom and stretched wider.

NOTE: If a fixed bar remains on the screen for a long period of time, the image can become parmanantly engrained in the screen and cause subtle but permanent ghost images. Never leave your TV for long periods of time while it is displaying these images.

Zoom picture size [for 16:9 formats]
The entire picture is uniformly enlarged --it is stretched the same amount both wider and taller (retains its original proportion). The right and left edges of the picture may be hidden.
OK.

Try cleaning the lens gently with a lens cloth or maybe a damp paper towel? Other than that - you may have something stuck in your lens that is making everything blurry when you zooom in...or the lens may need to be replaced to be fully functional. Do you notice any blurry spots when you zoom out that get bigger when you zoom in? If so something may be stuck in your lens. Good luck!

Press the RATIO button repeatedly to select the desired picture format. You can also adjust Aspect Ratio in the OPTION menu.

1. Set By Program. Selects the proper picture proportion to match the source’s image. (4:3 → 4:3, 16:9 → 16:9)
2. 4:3. Choose 4:3 when you want to view a picture with an original 4:3 aspect ratio, with gray bars appearing at both the left and right sides.
3. 16:9. Choose 16:9 when you want to adjust the picture horizontally, in a linear proportion to fill the entire screen.
4. Horizon. Choose Horizon when you want to adjust the picture in a non-linear proportion, that is, more enlarged at both sides, to create a panorama view.
5. Zoom 1. Choose Zoom 1 when you want to view the picture without any alteration. However, the top and bottom portions of the picture will be cropped.
6. Zoom 2. Choose Zoom 2 when you want the picture to be altered, both horizontally extended and vertically cropped. The picture taking a halfway trade off between alteration and screen coverage.
7. Cinema Zoom. Choose Cinema Zoom when you want to enlarge the picture in correct proportion. Note: When enlarging or reducing the picture, the image may become distorted. You can adjust the enlarge proportion of Cinema Zoom using D / E button. The adjustment range is 1~16.
   

It sound like you have some dust particles or a smudge spot on the CCD screen (actually on the low-pass filter in front of image chip). To leave an image on CCD, the dusts must be closer to the image plane to be registered so it should be somewhere closer to the screen or right on it. Take a look at the screen with "CCD Clean" mode and blow out any dust. If the smudge is on the screen, I recomend trained tech should clean it. good luck.

Right Click on an open spot on your desktop.

If your Operating System is Windows XP, choose Properties from the menu box that pops up when you right click.

A new window will open up. Click the Settings tab at the top right.
On this menu you should see a slider bar near the bottom left under "Screen Resolution". Left Click and hold the mouse button on the grey button and move it on the slider bar over to the right one spot. Then click the Apply button on the bottom right of the box. The screen may flicker for a second and your desktop will change size. If the screen covers the whole monitor and the black bars are gone, that may be the correct resolution. Click OK on the box that has a timer and is asking if you want to keep the screen that size. If the screen does not look correct, click No and you may need to slide the button one more spot over and try the next resolution and Apply until it looks correct.

Under the slider bar as you move it over a line at a time will be 2 numbers like this 1024 X 800, and when you move the bar over the numbers will change. I believe the optimal resolution setting numbers for the 20" monitor you have should be 1680 X 1050 for the widescreen. You may want to try that setting. If it looks too small, try sliding the bar to the left and try each resolution setting.

Here's a screetshot of what the Box with the slider bar looks like: http://technophobik.co.uk/vxp_control_panel/f007_settings.asp

The screen may flicker and change the size of your desktop. Click OK if the screen looks correct or click No if it doesn't look correct and try sliding the button over one more line.

Hello:

There are two micro motors that take care of the focusing. Either one or both may have become defective (open internal coils) or an electrical connection gone bad and the controller needs to see these "loads". If it doesn't see these, it sends out the error code. In the photo they are located on the left and right lower portion.

sir u contact ur near service center this is simple problum just clean ur camera CCD

My Nikon was having the same problem with the stationary black spot. I used a can of Dust Off ( the original compressed gas duster). I just removed the lens and held the camera upside down (lens facing the floor) and blew my compressed air inside and my black spot disappeared. Just a thought you might like to know !! Good luck.
