I checked and there is power to the 320V ballast, there is power to the color wheel but is not spinning. The three LEDs on front of tv flash after 3 attempts to turn TV on, but first the lamp LED flashes. Do you have any other ways to check to see whats wrong with my TV. Thanks, Brandon

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 Any buzzing,humming,or high pitch sounds? If you do it could be an issue with the color wheel.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.
I have a HNL5065W samsung that i just repair if it was the lamp you would not get sound,When Lamp goes out set will not come on only Flashing front lights, how long does yours play before cutting OFF? There is a couple of capacitors that will go bad on power board,CK to see if any of the capacitors are puffed up on top if so thats your problem.,But remember Ballast starts up LAMP CK the big capacitor on ballast board and small ones ,also Keep in mind it could be Ballast,if set keeps playing with sound and no picture another thing make sure nothing has come unpluged on DMD board, this board also will keep lamp from firing.OK heres another thing IF COLOR WHEEL is not spinning correctly lamp will not fire up, if it spins to slow or too fast most samsungs start out with Bad Color Wheel.I Buy on E-Bay got My lamp for 85.00 Ballast board 55.00 Ballast board at other companys 117.00 plus shipping! Color Wheel was 65.00.
You are on the right track for the repair of the set. You should be able to hear the color wheel spin up as the lamp begins to glow. If it is not spinning then that is the first thing I would replace. During the power on sequence, if the color wheel is not detected as spinning, the set will turn off the lamp. Since the lamp is firing up, I would not suspect the ballast. I would say having a spare ballast and lamp is very good idea for these televisions. I have repaired these sets before and have ended up replacing the lamp, ballast, and color wheel all at the same time. I hope this information allows you to resolve this issue.

If you have verified the votages are there at the color wheel and its not spinning the color wheel is most likely defective. the sound you hear when spinning by hand is most likely the bearing but that shouldnt stop it from spinning. but as i said if the supply voltage is present but it still wont spin. the color wheel must be defective.
Hello Brandon B Great Job at trying to fix your own TV.....Bravo!! Ok, you may very well have a bad Color wheel. You have already change your Ballast and Lamp. The lamp would have been my first step. If you have a defective color this will surely cause the set not to come on. The DM board detects what going on with the color wheel and will not start the lamp. There are 2 types of color wheel listed for this TV.
List price $100 BP96-00674A COLOR WHEEL (FOR TYPE L3 VERSION PW03 UNITS)
List price $100 BP96-01103A COLOR WHEEL FOR TYPE L6 VERSION PU01 UNITS
As part of the power up sequence on the Samsung HLP-4336W the lamp isn't turned until timing pulses are detected from the color wheel. The color wheel motor is powered through the flat brown four conductor ribbon cable and the timing pulses are detected over the the three conductor ribbon table.
YOU PROBABLY NEED A DMD BOARD. THE COST OF THE BOARD IS $900 . YOU CAN GET A LIGHT ENGINE FOR $700 THAT HAS A NEW LAMP, COLOR WHEEL, BALLAST AND DMD. WHAT A DEAL . THERE IS A $400 CORE ON IT SO YOU WILL HAVE TO SEND BACK YOUR NEW BALLAST AND LAMP TO GET THE CREDIT BACK. WHEN I GIVE A QUOTE ON THESE SETS FOR REPAIR MOST OF THE TIME IT EXCEEDS THE VALUE OF GETTING A NEWER BETTER SET. DON.
