My problem is: samsung hl-p5063w. I have a new lamp and it works fine. The fans work all right. The color wheel works well. But no picture, only the screen is black. Low light without image. The timer light blinks only when changing channels. The sound is good. Spleaker

remove and inspect the lamp the model indicated uses---you can usually also look from the rear to see if lamp comes on at all---set also prone to bad color wheel--grinding or high pitched fan like sound--it faces the lamp--with lamp removed look to see it is not shattered or missing pieces and that lamp not shattered inside.
typical color wheel

Color Wheel BP96-00674A Located right behind Lamp Pull Lamp out use a flace Light and you can see Color Wheel.

A bad fan will keep the machine from producing an image but I suspect it is a bad color wheel. When color wheel fails, you may hear a high pitched whine and no image. No image can also be caused by a burned out lamp, bad ballast or power supply board. You can call 1-800-samsung to find the nearest service center.

Remove projector assembly and clean out dust from cooling fans inside of it. It will require some disassembly. Then have capacitors checked on the power supply.

Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!

Loud sound you are hearing is coming from your color wheel and has your Lamp ever been replaced? this set has 3 Fans they all must be running for set to operate correctly! Encompass Parts has Boards and Color Wheel But for Lamps Mats has them for 99.00 1-800-628-1118 and EC Parts 1-800-638-3328

Replace the color wheel

every time I see this itbis a cable or plug that was left out or one that got pulled on and pulled the connector up out of the plug a little, you need, and not by sight by your hands to go over every plug and connector till you find one.

A Blinking Lamp LED is the most common failure indication. It can be caused by a bad lamp, a bad Ballast, Color Wheel not operating, Fans not turning, or even other defective Boards. I would suspect the Ballast or fan first though.
