What is causing my picture to darken on my samsung 60 inch dlp tv

it may caused by the dust.
open up the led tv and clean it using the blower.

have you checked your connections and sure your getting a HD signal for the clarity . as to Darkness it may be a lamp failing and that also may be your clarity problem if its getting to the end of its life span on the bulb

sound like you have samsungs dlp white spots plague, which just gets worst. samsung are aware of the problem, so you need to get in touch under the warranty.

This condition is under a class action law suit..If U call Samsung I belive they will check it out for free..

replacing the color wheel on a samsung 62 inch DLP tv

The lamp is the only thing that will cause the picture to go darker. According to the model you have the lamp part number is BP96-01472A. The noise you hear could possibly be the color wheel itself. The way to tell is when you turn off the TV the lamp stays on for about 10 seconds longer. Once the lamp shuts off if that noise goes away then it is a bad color wheel. Any noises past that would be a fan. Please take a moment to rate my answer. Thanks...

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.

You have a bad Light Tunnel in the Light engine, you can replace the engine, or try to replace the tunnel.
