Hey there, Your issue is related to the small chip inside the Tv, I believe they are called the light engine. It is a small plastic frame with what looks like a graduated glass pane in the middle. Over time this begins to show its age and amount of use by casting the shadow to which you refer. For some it appears as yellowing in spots. It is replaceable but should only be done by those with the right skill and tools. Maybe double the cost of the lamp or a little more depending on Brand.
[u][b]LCD Monitor Shadow Effect[/b][/u]
This problem is best described as the LCD monitor "Shadow Effect". The solution to this very simple. No software or hard ware changes required. The cables that are connected to the LCD monitors are causing the problem. Its also called as electromagnetic noise or electrical noise. [u][b]Solution: [/b][/u]Keep the two cables - (power cable and moitor display cable), that are connected to the LCD monitor as far away as possible with each other and also away from other electrical cables.
Thats it. Your shadow effect is fixed.
Thank you.
probably not something is up have you ever had direct sunlight hit the lens maybe at the beach? Or lots of heat can damage the lens you. lens replacement is just the same as getting a new camera. hoped that helped.
Try moving a medium powered magnet (not one for picking up heavy objects and not a refrigerator holding one) over the distorted area. If that doesn't work, try a more powerful one. This worked for my Toshiba LCD. Good luck!
Projection TV correct? This may take some work but it is common for a spec of dust to settle onto the Mirror inside the TV, The back side of the TV screen or onto the Lens from which the Video image is projected. Some TVs have ports that allow you to access the inside of the TV from the side, others you must remove the screen.
This is not something to do every day or every week and it will not improve the picture. You only do this when you notice that it is dirty. Any more than that and you yourself will create a bigger problem. ONLY LIGHTLY DUST the screen. Soaps, water and windex will leave streaks, damage the screen and cause more trouble.
Projection TVs are the eqivalent of a big flashlight showing onto a wall. Put you hand in front of the light and you get a shadow.
Inside you TV there is a light (the TV picture) that bonces of a mirror attached to the inside of the back of the TV. The light reflects off the mirror onto the back of the screen. You view this refelected image from the front. Spiders commonly make webs inside the TV that appear in the picture. Dust Bunnies may get blown into an area and become stuck in the way. Sometimes a lite tap, shake or blow may remove this also.
