Light in wrong, however I wouldn't waste the money on this unit. Light engine will fail in 3 to 4 years and show a yellow spot at first.

(ie past post)
The yellow spot is due to the BLUE LCD and/or lens assy cracked, reason, to much HEAT! The blue is the darkest color and hold the most heat, so it goes first, always! In some cases it’s only the lens, however most of the time LCD is damage to. Parts are available, however install and alignment is timely. Quick fix is the complete light engine, which for model# E44W46LCD is part# 3141VSN916C, which customer cost is $1,449.27, wholesale for about $1,065.21. Rebuilt, if you can find it around 850.00 to 950.00. However the rebuilt does not always look as good as factory. My advice, TRASH set. This part will fail again in about 3 to 4 years, unless you watch a lot of white video. Remember, on a black or dark picture, all three LCD are blocking 100% of the light, causing extreme heat within the light engine. It’s a bad design.

I have a Samsung HLR5656 model and the picture is now very dark even DVD are dark. Still watchable but it looks like everything is shot at night time.


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is BP9600826A You can find it here:http://www.discount-merchant.com/Samsung-BP96-00826A-Lamp-Enclosure-p/samsung-bp96-00826a-lamp-enc.htm?Click=48173. Have a blessed one!

Dark picture


I removed the back from the tv and cleaned the lamps, mirror and inside of the screen with window cleaner. The image is now clear as the day I bought the tv.

How can I adjust brigthness using other option than F9, because it does not work


Per the user manual, the brightness is toggled by holding the Fn Key and pressing F10. You post made no reference to the Fn Key being pressed. If using an external keyboard press scroll lock twice then F10.
