Please try reducing the contrast a little and increasing the brightness till the dark shots are clear. Please also check the back light setting. It should not be too low.This should make all the dark scenes clearly visible if it only a setting problem. In case the overall brightness has reduced, please consult a local TV Tech.
Have you checked all the back lights. If not check it. Replace the faulty ones. If you wish to get some details, check the site linked here. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/
#1: takin pic w/o flash, please make sure you are in a well-lit (sunlight lit is best) area. please make sure focus is not moving, and camera is not moving. when green box appears, please be very still to get clear pic. i donot use flash, flash does exactly wat u say. so i use "scene" w/o flash.

Lcd tv sets are lit by small glass florescent tubes called cold cathodes and, are powered by: ballasts called inverters... these go out just like your office florescent lighting the parts can be purchased online from electronic parts houses and, are easily replaced
if the picture is REALLY dark, like you can just barely see it in a lit room, then the backlight might not be lit. LCD TVshave backlight that shines through the LCD screen which allows you to see the picture.
If it's not the backlight then it would be the brightness/contrast settings that need to be adjusted. If the picture used to be normal and all of a sudden went dark, verify the backlight. Normally you can look through the slots on the top of the set and determine if the backlight is on. If you can see a bright light through any of the slots, the backlight is probably OK... go after the brightness/contrast settings.
Your Polaroid Fun! Digital 320 camera does not have a flash. If pictures are coming out dark, it's because there wasn't enough light in the surroundings when the picture was taken.
Remember, it's important to take photos in brightly lit surroundings.
When taking pictures indoors, make sure that the room has bright lighting. For best results, take pictures during daylight hours with a combination of indoor and outdoor light, preferably near a window.
