Your problem could be your lamp is not seeted all the way in. Take you lamp out and put it back in. Or it could be you ballast that lights you lamp is bad. You may need a new ballast.

Replaced the balast, tv not longer turns on and off but now it has a kind of pulsing picture. Am I looking at a new bulb? a new color wheel ? or some other surprise that I haven't heard about?


Lamp is possible especially if the ballast was bad--it powers the lamp.
Color wheel will usually display some issues--high pitched whine or fan like noise---with the lamp removed look where it faces--color wheel is there--any broken or missing pieces and it is the problem---

The wheel is directly connected to the set---set will detect if wheel not moving or moving too slow etc and almost instantly turn the lamp OFF.

Your color wheel has gone bad. I recommend this repair to only be done by a qualified Samsung service center. Part costs less than $100

Samsung DLP TV makes noise even tho its not on.


from your description sound like you might have a stalling color wheel. the color wheel on a dlp is what provides the color. it is a spinning disk of different colored glass. that must reach certain speed for the tv to operate. and like all moving parts eventally break, and need replaced. you may be able to replace this if your tecnically inclined but i recommend a tech. it may need be setup

How do I remove/install color wheel/balast on a samsung hl-p5063w


We just replaced our color wheel and it took about 2 hours.  We used this site because it was the only one that somewhat resembled our TV http://guides.fixyourdlp.com/samsung/bp96-01579a.php  Our TV had a loud humming noise and no picture.  We also had to replace the bulb.  Hope this helps.

go on the samsung website get the part number and then go on ebay and purchase the ballast. its half the price. pull out lamp assembly and right under it is the ballast. 2 or three screws hold it in. and there are 2 plugs that need to be undone. its very easy. hope this helps. i did it in about 15 min
