After reading all the posts on Samsung DLP's... well I guess misery loves company so here goes. I got a new lamp for my HLR4667W and it does not light up. From the posts, I gather the ballast is possibly the next culprit. Where can I find instructions on replacing or testing the ballast?
Thanks |

Hi Frank,
Here is how to test the Ballast Board, Color Wheel and Fans. If you need further assistance go to my post listed above.
Pull the lamp housing
Tie the door switch up to the closed position
Turn on the TV
All Fans should run, Color wheel should spin listen or shine a flashlight in the lamp side window to verify
Watch at the left back side of the Ballast board for the starter to flash it will cycle flash three times
Pull power cord from back of TV to shut off or it will continue to try the three attempt cycle
This will verify the Color Wheel and Ballast board are getting power and most likely your problem is a bad lamp but you should also do a voltage test on the two prong plug on the Ballast board to see if there is 380 volts dc from the power board. |

Thanks atracker. NO DC voltage a interface, colorwheel spins and I already put in a new bulb, so I guess it's the light ballast? The code on the bottom is BP61-00728A. There is a code on one of the PC board components. Brand is Osram code is PT VIP 2AC/380 O1. Which do I use and anything special that I need to do during or after installation?
Thanks

Hi Frank,
Did you try the above test? Did you buy a generic or the right lamp for your set? The wattage does make a difference for startup. Can you provide me with your full model number so I can provide you with the right part numbers for your lamp and ballast board. If you will let’s take this over to my topic so I can keep track. I have also added a test for the DMD board there.

ATracker,
Nice to have someone to help like you and others on the forum. I have a HLN467WX for 4 yrs. Now all of sudden no more pic. When turned on, only sound comes up for 2 minutes, dies for 5 seconds, then back on with sound for another 2 minutes. Cycled this 3 times then turns itself off and all 3 LED lights flashing on.
Bought a new lamp and installed without help. Followed your protocol you suggested April 10, 2009 as following:
Pull the lamp housing
Tie the door switch up to the closed position
Turn on the TV
All Fans should run, Color wheel should spin listen or shine a flashlight in the lamp side window to verify
Watch at the left back side of the Ballast board for the starter to flash it will cycle flash three times
Pull power cord from back of TV to shut off or it will continue to try the three attempt cycle
When turned on, 2 fans are on, but color wheel does not move at all. No churning noise. Ballast has click sound on turned on, but no flash seen.
I am trying to decide buying either a ballast OR color wheel to try at this time. Both expensive, so want to ask your opinion on which is more likely the culpit. Please help!
