your lamp bulb is probably finished so get a new lamp bulb they are easy to replace just look for a small panel on the side of you tv all you need is a flat head screw driver to open the panel and you should be able to pull out the lamp bulb

SOURCE: Dark Screen

The lamps in these normally last about 3000 hours (if your really lucky). The bulb will start to loose it brightness as a matter of due course at about the halfway mark. It maybe that you are running the unit in the non economy mode that they are fading faster then normal.
The sets have a reputation for not being good with lamps though.

Have a look at the lamp though, make sure it has been off for at least an hour to let it properly cool and check for dust that has settled on it. Also if you wipe the lamp, make sure it is with a dry cloth, or allow plenty of time for any moisture to completly dry before turning it on if you use a damp cloth.

The set does use a lamp for a light source and average life is 2 years or 2000 hours---many lamps before they actually fail get to be darker.

you cleaned the reflector glass, then tried to make the manual adjustment of the color to have good convergence. you can do the adjustment in the menu set up. if can not get with adjustment, their might be a problem in the convergence circuit board.a bad convergence ic or resistor.

You need a professional.
Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.
