I have a 52" Samsung rear projection TV. I've replaced the lamp, ballast and color wheel. I now have shadows on the perimeter of the screen. At first the technician said moisture got on the inside of the lens and he removed it and dried it, when put back in, the spots were still there. He then said that we should leave it out to air dry for a few days. He just put it back in on Thursday and the shadows are still there. According to the tech, I need a new lens, however, he cannot find the part by itself, only the entire engine of which most of the parts have been replaced. Is there a solution to this problem or should I just purchase a new TV????

It sounds like the main power supply has a bad capacitor. its a typical issue with a lot of electronic. look on the main power board that the outlet cord comes in to the TV and check all the cylindrical components for swelling, leakage, or singe makes.
Change the tv Ballast board too.This board only job are to help it to ignite the tv projection lamp. This tv also have a colors wheel design into it too.If tv have colors pictures flashes or Black& White flashes within it pictures or tv have grinding noises or humming sounds,than the tv colors wheel it is warp and dead.This tv colors wheel must be replaced,because the colors dis wheel is warn out.
This DLP tv model don't have a colors wheel.U hear alot of clickings sound,when power turn on?The Ballast board it dead.This board,job to help projection lamp to ignite.Tries websites like Partstore.com,Ebay.com to buy the Ballast board for the replacement.
Since you have replaced the lamp and wheel, next would be the ballast and power supply board. These provide power to the lamp and Samsung recommends replacing both at the same time. If power supply board is bad, it can destroy the ballast so replace both. This usually takes care of the problem.
Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.
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 Hi,If your tv is a dlp you might be experimenting a color wheel problem.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. Also make sure everything is properly closed (door cover) if it's not properly shut it won't be able to light the lamp.Have a bless one!
You may still have an issue with the color wheel. That or the ballast is bad. I don't think it's the lamp if you've just purchased a new one. It's possible that you've installed the color wheel wrong, or that the color wheel is defective.
Ballast Board that connects to Lamp it could be bad or recheck to make sure its pluged in good anyway Ballast Board is what turns Lamp on Loud Noise means Color Wheel which can also shut set off Id say Color Wheel Call Encompass Parts 1-800-638-3328 they List all the Parts you need Part# for color wheel is BP96-00674A cost 129.69 They also have Service Maualfor your TV. Also Look on E-Bay under Electronics found some good deals thier Got my Lamp for 85.00 and Ballast Board for 65.00
Hi,If your tv is between 2-4 yrs most likely it's time to replace the lamp.If you hear continuous clicking it could be the ballast which is the board that powers the lamp.If you hear buzzing it could be the color wheel,which is a spinning wheel that creates the color on your tv.God bless you!
