My DLP won't turn on. 3 lights on front blinking indicating the lamp is out but I have replaced it and it still won't turn on. Someone suggested it could be the ballast and I replaced it as well. Still 3 flashing lights come on. Don't think the color wheel is out because it is not making a grinding sound. When I turn the TV on it makes its normal beeping sound and I hear a click like the lamp is going to light up but it will not. It wil do this 3 times and just start flashing all 3 lights at me again. I have to unplug to get it to stop. HELP!!!!!
If your having the "3 light" problem it could be an indication of a bad lamp however if there is a buzzing or a grinding sound it could be one of two moving parts. The color wheel or the cooling fan. I would go the cheaper route and replace the color wheel first. The thing is the lamp will not turn on if there is a problem with one of the other two parts. TRUST me ... I've replaced all three parts just to find out it was only the cooling fan. (at least I have another lamp handy when the new one goes out). The motor on the cooling fan is too small for such a big fan so I would definately try it first. It's a big problem with the DLP tvs. Hope this helps.

This is most likely your color wheel if it does not get up to the correct speed the set will shut down. You do not have to hear anything grind that is just the dead give away. Its about a 90 percent chance that this is your problem and would be the next place I go. If you order the color wheel make sure you get the correct one there are two for this set. You need to look if you have an L6 chassis or L3 this will let you know which one you need. If you call samsung they will need to know the lamp code on the left side.

Correction on the previous post ... change the cooling fan first. Not the color wheel. You'll save alot of money.

First, A common mistake made is when you insert the orange ribbon cable from the Color Wheel into the DMD bd. To correctly insert the Ribbon Cable you need to look at both sides. You will see a shiny silver side and a dull black/orange side. You must insert the shiny silver side AWAY from the Color Wheel or towards the rear of the set. Now for the Ballast. When you power up the tv,Do you hear a short Buzzing sound? If you do that means that the Ballast is trying to fire up the Lamp and is working. Next, do you hear the Color Wheel spin up? If you do not then you have installed the Color Wheel incorrectly and you need to repeat the installation while making sure that you hold the rubber gasket in perfect place or else it won,t work. Chances are the gasket is in the wrong position and is binding the Glass Wheel. The Ballast is on the right side of the engine and on top of the Lamp Housing. You will see two RED High Voltage wires coming out of one end. Don't worry, there is no stored voltage in the ballast so you won't get a shock providing you have unplugged the tv from the outlet. That is the first step before you change any parts any way. Listen for the correct start sequence. With the rear backing off and the Safety Interlock Switch is being held in the up position, turn on the set. First sound you hear is a clicking which is the power on relay engageing. Then you will hear the fans turn on and then the Color Wheel spin up. Once the Color Wheel spins up and comes to full RPM then the Exciter on the Ballast will Buzz for less than half a second and then the Lamp should light up. Now if you have installed the correct Lamp and correctly installed the Color Wheel and you either are holding up the Interlock Switch or have reinstalled the rear cover and tightened all of the screws you should have a working tv.

Sounds like you've already gotten into the repairs. The three major things that fail on DLP are the bulb, the ballast and the color wheel. If your bulb is new and you aren't getting anywhere, replace the ballast, if that is still a no go, then move on to the color wheel. If replacing those three doesn't fix the problem, you will have to whip out the multimeter and start looking for problems on the PSB. You can get a ballast on ebay for about $100. Start there. The color wheel should be very freely moving. If something is grinding and hindering the movement at all, you need to replace it. That grinding may not seem like much but it is likely enough to keep the wheel from spinning at proper speeds. The sensor then kicks in and tells the brain that there is a problem and the brain keeps the ballast from firing the lamp.
Good luck.

Was the replacement lamp the same part number as the original as there are different arc gaps for different lamps and the wrong arc gap will cause the lamp not to light. Since the ballast is powering up the lamp should light if the baalast is matched to the correct arc gap of the lamp being used.

I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).

I've got the exact same problem. I used to unplug the TV to force a reboot--that used to work -- but not any more!
I too am having the three-light problem. It happened first within a month of buying it back in May 2004 and a service man was sent out. He replaced the bulb and said they had been having problems with this model. It has continued to happen in waves but usually sorts itself out by repeatedly turning the power button on. Today, after 5 hours of trying, the 3 lights are still blinking and unplugging it has not worked. Even though I love the TV, I'm tired of having problems with something that was so expensive.
I have the same problem described on the other posts. I have replaced the bulb recently and just replaced it again thinking that it my be the problem. Not so... If it is the color wheel, are there any tips on replacement, and cost?
I have had the same problem with our TV, we have replaced the lamp and the color wheel and still nothing! The lights are blinking indicating the lamp is out and when I try and turn the TV on the fans come on making a humming sound and after three attepmts the TV shuts down. This is a frustrating problem for such an expensive TV that is barely over 2 years old. Samsung has not been able to offer any help and seem to be ignorant about their product. I guess I will have to try a new ballast and if that doesn't work junk the TV!! I won't buy another Samsung after this!
I came home and there was a loud humming in the TV I tried to turn it
off and it would not. Now it will start for a second then the humming
starts and then turns itself off. The lamp light blinks along with the
red button that says "hot" I think. Does this sound like its the "color
wheel" or something else, and is changing the color wheel hard and need
of a teck or is this something your average Joe can fix?
Same problem. My tv will turn on for a few minutes in working order, then shut itself down and the front three lights will blink continuously. Once this happens, I can't turn it off. The lamp, timer, and standby lights all blink. The lamp obviously still works because it will turn on - it just wont stay on. It did this for one day about a month ago and just began working on its own. I am quite frustrated because of the cost of the tv. My old, cheap tv's are all working great and here my new, expensive tv is ****!
same as above. wont start. Tries three times then shuts off
The ? is how do you tell if it's the Fan or the Color Wheel. THe spinning/grinding noise has gotten louder and louder on my DLP and now it starts up with a really loud grinding noise and the TV won't turn on. It was turning on before and the colors on the tv didn't seem right for a few minutes then everything would run normal. Now the TV just goes straight to that lound humming/grinding noise and then all 3 flashing lights go on. I'm pretty sure it's not the Ballast, the Lamp is only a few months old. So do you think it's the fan or the Color Wheel or something worse?
what do i do
did the cooling fan fix the previous problem
