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.

I have a HLP5063wx/xaa and when I turn if off I hear something like a fan winding down. Also every once in awhile when I turn it on the people are red but i turn it off and back on and everything is


Yes the fan can be replaced but I believe your issue is actually the colorwheel which is going bad which can lead to color issues eventually the set will refuse to power up if the bearings fail completely inside the colorwheel

Have sound no picture lamp does not appear to be bad when looking at it yellow light blinks the shuts off tv then tries to start and can hear sound but no picture it will keep doing this till i turn the tv...


listen for the colorwheel noise
you'll recall hearing it "wind up" as the tv came on
many of these will go bad and then it will never fire the lamp because the colorwheel doesn't get up to speed

if you don't hear it, suspect the wheel, its hard to get since toshiba never had it as a seperate part

if you do hear it, its probably a bad lamp driver, but unlikely

let the tv go and go, it will try like 7 or 8 times and then eventually spit out an error. your user manual has the error codes, it will tell you if its the colorwheel i belive.

let me know if you need further assistance

The picture come on then goes black and then the television turns off. I thought it might be a bulb problem (4 years old). So I bought a new bulb, seemed to work and then began to go black again with all 3...


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.

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.

When I try to cut on the TV all 3 indicator light start to blink.


listen to the tv from the rear you should hear a slight wind up of the colorwheel just after the power button is pressed. after that the lamp ballast should attempt to start the lamp . if the lamp is bad you will hear a buzzing and see no light coming from the lamp door. if you dont hear that winding up of the colorwheel its bad and needs to be replaced

Is it easy to change a color wheel like the lamp? or i need to take it to a tv specialist?


the colorwheel is not as easy as the lamp to change. you have to remove the light engine from the tv and remove a cover from the lens and a cover from over the colorwheel then two screws that hold the color wheel and two wires. sometimes new codes must be input into the service mode. i suggest letting a professional do it.

Colorwheel not spining new 1 doesn't spin either


Its a tach fan connector. If the fans are not running, the system will not power up. If the back or lamp cover interlock is not closed it will not power up as well.

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.

Color wheel was making a sqealing noise then locked up


The clorwheel is the problem. Once the bearings go bad in the colorwheel, it's toast. Replace the colorwheel and you'll be ok

High pitch sound


If the sound goes away when you turn it off, its the colorwheel. If it keeps running for another 1-2 minutes (cooldown) then its a fan. Both are changeable by a technical person, the colorwheel being much more intensive disassembly. Let me know if you need help there.
