Sounds like a bad color wheel----remove lamp---the wheel faces it--look for missing pieces or the wheel shattered---these are known for the wheel making a loud high pitched sound or even a grinding sound if the wheel shatters.

if wheel bad You Tube has video instructions for replacing it---seen several people able to do this themselves in about a hour. Google the model number to ("color wheel") to locate a replacement on the internet.10_24_2012_4_08_47_pm.jpg

After 10 sec. after start up the tv starts to make a large growling sound for about 5 secs. then repeats every 15 sec. sounds like if might be a fan. How many fans in this t.v. . Took the back cover off...


That growling sound is most likely a your color wheel. Often, a color segment breaks free and causes the wheel to become unbalanced. I would suggest searching for a tutorial or "How-To" on replacing it. Basically, you need to disconnect (about 4 connections) and remove the Light Engine (2 screws). Then pull the cover off the color wheel housing (to the left of the lamp, 2 screws). Disconnect and remove the color wheel (2 screws and 2 connectors). You will need to use a vac the glass out from the lost color segment(s). Here's a tip for reassembly: color wheel 4-wire ribbon.. copper on the connector should face you. Also, the lamp door switch must be tripped or the TV will not fire up. I hope this was helpful.

Check Fan No. 2 Error Message


The DMD board you installed is bad. It senses the detection line from the fan and generates the error code. Try installing the old DMD board.

This varies a little depending on model number of set.

Usually a bad color wheel will produce a high pitched sound or even a grinding noise; some sets may actually shut down if the wheel is bad or shattered.

To determine if you have a bad color wheel:
  1. Turn set off and wait for main fan to shut off.
  2. Unplug the set.
  3. Remove the lamp door and then remove the lamp.
  4. In the direction the lamp faces you will see a round opening; the color wheel is facing this opening. It is a round plastic wheel with colored segments—we want to look to see if any of the segments are missing; a shattered wheel should be clear to see.
  5. If the wheel is shattered or makes the high pitched fan like sound you can with the model number go online to someplace like Ebay with the model number of your set and find a part number and replacement wheel for your set---most of these are 70 to 90 plus shipping—make sure you get the right part.
  6. The wheel turns at about 14,000 rpm and eventually the motor seizes up causing this problem.
  7. Depending on model number there are some variations on how to replace it; but for the most part it requires the following.
  8. With the set unplugged remove the entire back cover.
  9. Locate the optical light engine dead center in the middle of the set. Some models have a large square box in front of it that you have to unbolt and remove plugs from one side—mark the plugs so when you remove them you can put them back in the exact same place.
  10. The Light engine has to be pulled out of the set to replace the color wheel; this kind of repair usually takes less than an hour from start to finish.
  11. Once you get the engine out you will find a somewhat square black plastic shroud on the right side of it----3 philips screws secure it to the frame of the engine.
  12. Remove the screws and you should be able to pull the shroud up and away.
  13. The Color wheel has two cables coming out of it; one is a 3 or 4 wire small square plug and the other is a flat ribbon cable. Be very careful when you remove the plug with wires—some people break the wires and then have to get the plug out of the socket with care. Both plugs connect the color wheel to the optical engine. The flat orange ribbon cable only has contacts on one side-WHEN YOU REMOVE IT NOTE WHICH DIRECTION THE CONTACTS ARE ON---if you put it in backwards(it can be done) the lamp will not turn on.
  14. You need to be careful when you replace the shroud over the color wheel so that the two cables(the ribbon cable and the other one) do not get pinched by it.
  15. With the wheel replaced; install the light engine back in place.
  16. All these sets have a safety switch on the back edge of the frame---it is a lever that will not allow the set to be turned on with the back removed. After you have installed the light engine back if you want to see if it worked; tape or hold the lever(usually blue and on the right side as you look from the back).
  17. If the set comes on and the lamp comes on do not look directly at the lamp---Once you see you have a working set turn it off and wait for the lamp fan to shut off in back—usually a few minutes.
  18. Bolt everything back and replace the back cover also---this should complete the repair.
ALSO IF YOU GOOGLE YOUR MODEL NUMBER WITH COLOR WHEEL REPLACEMENT after it there are several sites with written and video instructions for this repair.

Samsung HLP4663W needs fan replaced.


Apparently I was in denial about the color wheel. With my son's help, I pretty much confirmed that it was NOT the fan. I could have replaced the fan after pulling the boards out to do the color wheel, but didn't want to shoot myself in the foot. I had my son hold the lamp saftey switch so we could turn the set on with the lamp access panel off. Then after the buzzing started, I VERY, VERY carefully reached in & touched each of the 2 fans to see if the pitch of buzzing changed, or if the fans were vibrating at the same frequency as the buzzing noise. It did not change one iota. So I went with an educated assumption that it was in fact the color wheel (just like all the posts in the threads had said). Our set was born in 10/04, and the color wheel was much easier to do than the one in the excellent step by step post that I found elsewhere. The procedure for accessing the fan (if the need be) is basically the same as the colorwheel replacement procedure, as far as removing panels & boards, etc, and gaining access to the fan (you can't do it just thru the lamp access panel). It took me & my son about 2 hrs (including the fact that we forgot to reinstall the colorwheel hood/shroud the first time we reassembled). We also didn't have that jumper to deal with either. HOWEVER, while the picture looks great for the most part, I think I may have to use the service menu to set the color levels correctly. The problem being with the black levels I think, because in a dark scene in a movie, shadows look blotchy, almost rainbowy in a somewhat pixelated sort of way. The new colorwheel came with a little sticker with the new CCA color setting values as well, but in researching the service menu access codes, I read one post where someone said that simply accessing the service menu (even if it's just to see how many hours you have on your lamp, without even changing any settings), will reset all your settings. I don't know if this is a problem for me, as I never changed the settings before, and never had it serviced by anyone else.

Mitsubishi 1080p 73'' DLP HDTV - Color distortion


This would be the little sensor on the light wheel. Its cheap, you can get them online for around $2. You will need to take the light engine out and remove the color wheel cover and remove the color wheel and then remove the sensor. You will have to desolder the sensor and remove it to replace with the new one.
What is happening is the sensor is overheating and not tracking the color wheel properly there for the colors get messed up. Once you replace the sensor the tv should work like normal. The part is
(Sharp GP2S40 Photointerrupter). It is very difficult to find because they are not made anymore. Most major online part stores do not carry them but I found a lot of them at Wright Hobbies. Good luck.
