Phillips HD TV - Picture quality diminished

Posted by taysams (My Page) on

Hello every one, this is my first post. I apprciate any help in advance.

I have a 61" floor console Phillips HDTV which is about 5 years old now. When we first got the unit it was fabulous. Now over time, the picture quality has greatly diminished.

Now I will admit, this unit has been used; a lot of on hours and also quite a bit of Xbox gaming.

We noticed a couple of months ago, that on dark movies, the picture quality is terrible. Detail can not be made out, and there is an over all blue/green milky tint to the whole picture on dark movies such as Pirates of the Carribean, Worlds End and even Hancock. It is totally unwatchable. Lighter movies and shows are ok, but there is no crisp picture on those either. Video games still play well on it, but sgain, not very crisp or detailed.

For those of you with Direct TV and their DVR, you will be familiar with the Pause screen; this is black, with the Direct TV logo rolling around like "PONG". This graphic has the light milky halo aorund it too.

After giving the background, my question is, can this be fixed at a reasonable price or should I look into investing money in a new one?

Blue ray does not help the picture at all, it is still milky and not crisp line and blurry detail.

Does anyone know what the problem is or has anyone experienced anything similar?

Again, any help is appreciated.

RE: Phillips HD TV - Picture quality diminished

This is due to the fact that the phosphor compounds which emit the light lose their luminosity with use. As a result, when certain areas of the display are used more frequently than others, over time the lower luminosity areas become visible to the naked eye and the result is called burn-in. While a ghost image is the most noticeable effect, a more common result is that the image quality will continuously and gradually decline as luminosity variations develop over time, resulting in a "muddy" looking picture image. Most plasma display producers state a 100,000 hours time before brightness halves, theoretically allowing for over ten years of normal viewing before the display dims significantly.
