Bad Colorwheel I need the procedure to change the colorwheel

    I installed the color wheel. A little nerve wracking, but all in all quit do-able. The color wheel wasn't exactly like the original. Had a ribbon wire instead of standard wires and the three torx screws holding the color wheel to its mounting plate were larger. I would think this will improve the bearing performance, by reducing vibration as the wheel spins.

    Looking around in the back of the TV. I don't think these things are getting enough air circulating around in there. I saw the cheap fan, and its position doesn't give it much room to circulate air. I'm wondering if these TV's suffer from getting too hot! Thus the bulb and colorwheels are failing from heat damage. I'm going to place a fan behind the TV to circulate more air.

Take off the back of the set. look for the lamp area. to the left of that should be the color wheel. please note you may have to remove the light engine from the set to get to the screws. there should be 2 screws on the color wheel. on some sets the top comes away from the bottom half of the set and you maybe able to remove it that way as well without removing the light engine.
becarefull with the wire and connector goin to the color wheel as it maybe a small ribon cable. if you unplug any connectors they should be easy to remember where they go.
good luck if you need more let me know as i have done tons of these.

    the color wheel could be damaged by heat if your vents get blocked by dust or dirt. you need to keep vents clean. also if you smoke around your set it could get sucked into the light engine and it will start causing your picture to go dark. keeping the bulb cool is a good thing, this will extend the life of it. also turning it on for a couple of hours is better then turning it off after 30 and goin to the store and comming back 15 minutes later to turn it back on to finish your program. its better to leave it run as turning it off and on also takes from the life from it.

Yes, it is possible to change a color wheel yourself, if you are very mechanically adept. It is easy to get to this light engine, once you get the back cover off the set. It takes a very small torx screwdriver and the color wheel itself is fragile. All that said, I still don't recommend it for most consumers, because it goes a lot smoother when done by an experienced tech.

when the colorwheels start to go bad this is the symtom that shows up. try this listen carefully to the rear of the tv near the lamp door. as you turn off the tv if you hear a slight grinding noise as the colorwheel slows down that means the bearings inside the colorwheel are dry and you will need to replace the colorwheel.

Will not turn on, red light flashing next to the menu button


if the fans don't turn on, they may be bad and needs replacing or rewired. if the fans turn on but not the lamp, the colorwheel may be bad (listen for a high-pitched whir when you switch it on. if no whir, replace the colorwheel). if the colorwheel is ok, replace the lamp.

After it warms up color goes to green and red


DLP TVs have color created by optical block or colorwheel. Colorwheel bad will make whining noise. This needs professional repairs. Check it out at www.fixurtvs.com.

The blue lights come on but the screen does not come on, what can i do to fix that?


if you do not hear a high-pitched whir or a loud buzzing when you start it up, you have a bad colorwheel. if the colorwheel is bad, the lamp won't light. if the colorwheel and the fans are ok, you may have a bad lamp. remove the lamp and check for bulges, black spots, fogging or flaking. also see if there is dust caked on the vent screen on the lamp. if you have any of those, replace the lamp. it is blown.

the colorwheel may be bad. if the colorwheel doesn't spin correctly, the lamp won't light. turn it on without the lamp in. look inside the lamp housing and see if the multi-colored glass disk (colorwheel) is spinning. if it isn't, or it's laboring, it needs replacing.

Depending on the version of software in the unit additional service alignments may be required.If the colorwheel was changed and the picture was fine before and now is bad this is the case.Only an authorized Samsung service center will have this information.In the colorwheel box there should have been a little sticker with the new peramaters required to align the new colorwheel to the software version.

only 3 things cause no light: bad lamp, bad ballast, bad colorwheel, or bad fan. if you feel the fan blowing and the lamp is good, do you hear a high pitched whir? if yes, the colorwheel works and it may be the ballast. if not, or it chirps, it's the colorwheel.
