How do I set my Sony DSC H50 camera to capture an image of 500 pixels

CCD in the lens assembly may be defective.check with a service center. We can get you the service manuals and spare parts

Sorry, there is no way to use DSC-H50 as webcam.

One problem with most point&shoot cameras is that they are designed to be pointed and shot. The camera takes care of things automatically, including focus.

The H50 doesn't have a manual focus mode. The best you can do for close-ups is to switch to one of the Macro modes. Press left on the control button (marked with a blooming flower) repeatedly to select the desired mode. See page 18 in your manual for full details.

A default setting is a setting that is preset at the factory

This is becasue the replacement part you purchased does not include the backlight. If you want the back light, you will have to remove it from your broken LCD (using a very low power soldering iron) and solder it on the new screen. Look at the new part and on the ribbon cable, there will be two metal like contacts. This is where you solder on the old backlight. You will also have to (carefully) remove the backlight housing from the old part and connect it to the new part. I got suckered just like you did, but I was able to make it work.

If you haven't a manual get onto the Sony site and try to find one there. You might strike lucky.

try with a new battery

use my dsc h50 as a web cam

Kindly initialize your camera from menu and camera will starts with factory default settings.

The DiMAGE 7i has four different image size settings; Full 2560x1920, UXGA 1600x1200, XGA 1280x960 and VGA 640-480. The recorded pixel size in each mode is almost equivalent to an image captured with a 5 mega pixel, a 2 mega-pixel, 1.3 mega-pixel, 0.35 mega-pixel DSC respectively.
