Re: How to change a ballast in a Samsung tv
IT is a little tricky but if you have basic had tools and a philips screwdriver you should be ok. You have to remove back panel and then pull out LIght Engine to access everything. Some models it is possible to not remove light engine, but i think yours you do. Also you have to remove the lamp competely and remove the little screw that holds the ballast connector to the housing for where the lamp plugs into the male connector. Located on the back of where the lamp plugs into on the light engine. Usually there are 4 screws that hold the ballast in place and you can remove those as well. Also there is some black plastic cooling housing that may require to be removed as well to accomidate this. But keep in mind all connectors are keyed so you don't have to worry to much, it only goes back together one way. Samsung was very good about this when designing set. I may even have a ballast i could sell you at a lesser price then anyone out there. If you get it out, Let me know and we can go from there. Do you hear it trying to fire the lamp? I would listen for that first and if you hear any kind of zzzziiiiiipppp sound, then ballast is probably fine. Maybe lamp could still be bad. I have seen new ones quirky sometimes. Keep me posted and i hope this post was helpful for you.. Cheers...Guru Jay

Yes,tries websites like Tvrepairworld.com,Partstore.com,Ebay.com to buy a projection lamp for the replacement.Tv have "LAMP"indication LED light is flashing or staying on.If the projection lamp on the tv now,been in used 4 or 5 hours a day watching the tv.The projection lamp has not been replace the last 1 1/2 or 2 years on the tv.The projection lamp life is over,require changing.The tv also making clicking noises,the Ballast board also dead,require changing too.The Ballast board help to ignite the projection lamp.
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.
U have a solid green light from the LED power light indicator right?U have this DLP tv for awhile like two or three years,and use it alots right?Never change the lamp and the ballast right?Change the lamp and the ballast should solved ur problems.
Hi, Samsung haves a known issue with the ballast, once you make a replacement of the lamp, sometimes its harder to ignite a new lamp that has 100% of gas inside than igniting a old lamp that has maybe 60% or 50% of gas inside. Just in order to ignite the lamp, the ballast needs to send some High Pulses of Voltage, as high as 15 kV (that is the constant clicking sound that you are hearing). In order to resolve this you need to change the Ballast Board.
I tried to look for your ballast with your TV Model # at samsungparts.com , but nothing showed up.
You will need to find out which ballast part # you have in order to find it online. To locate the ballast part # please check the end of this video, you only need to take the lower back cover of TV off. http://www.youtube.com/watch?v=0jr_9A5Xd2Q
Here is a link of a ballast I found
WARNING...The ballast can output 3000volts when it initially fires the lamp. Without the proper test equipment you could injure or even kill yourself.
You've verified that the lamp is good and now suspect the ballast?
