I have a magnavox 55 inch screen model nu is 6p5440w102. Picture is dark tried to lighten but wont brighten up anymore.


This is an older set------with back off you will see 3 large black cylinders with lens---these are the red, green and blue picture tubes.

Clean the lens with a lens cloth or paper towel with glass cleaner sprayed on the towel.

Annual cleaning of them is suggested as dust or dirty lens will cut down the brightness---this happens gradually over time and will make the picture darker and somewhat dull looking.

I do it with set on but you should UNPLUG SET and just look to see if dust on lens.

Simple and takes only a few minutes.

Let me know what happens.

Go into the tv menu and select the Preferences menu and set your picutre preference from Theater to Normal. The TV is currently in Theater mode, wich is for viewing with no lights on in the room. Switching it to normal lightens the pictue a lot.

Rear projection tv screen is dark


This unit does not have bulbs it has tubes.What is happening is the coolant fluid in the picture tubes is contaminated with a fungus( blue and green).A repair shop should be able to fix this problem for about $250.I do not recomend fixing this problem youself,but when it is fixed this unit will look like new

Dark picture


@ 6 years old I'd be willing to bet that it's time to replace the lamp. They lose brightness over time so that could be what the problem is.
