had a 46H84 given to me after "engine failure diagnosed" by Tech and $800 + estimate
Removed the engine and found the color wheel was very dirty and the shaft was not spinning well- cotton swab and denatured alcohol did the trick-
then cleaned the lens which was also dirty and while I was at it cleaned the mirror and backside of screen
Turned it on and WALLA- new set - the fan is a little noisy yet but liveable.
Total investment? 3-4 hours, 10-15 cotton swabs and a little alcohol- for the set on a rainy Sunday afternoon.
Just took a little common sense - the service manual is available online also for about $8 shows basic teardown but does not get into engine teardown which was very basic. My guess is a majority of engine failures after 4-5 years are simply in need of a good cleaning in reality

I presume the model number listed with the question is correct.
Usually a color wheel has some sort of noise associated with a failure or fault.
I have seen the wheel for this model on EBAY at over $260 and most of the Sharps sell it only with a replacement optical engine.
The color wheel faces the lamp and the pie segments spread and direct the light into the engine, if you heard any kind of fan like or high pitched sound the wheel may be your problem. Wheel is moving at about 12,000 rpm.
Usually a problem in the digital processing area will not shut the picture/set off.
I am not sure if it is the color wheel that it is a viable repair/ cost versus replacing set with something new.
Let me know if any unusual sounds from wheel etc during or at shutdown.
You may also want to Google the model number with color wheel replacement to to see if it is a do it yourself job.
In either case based on cost of part it may not be a good idea to fix it.
Let me know any information or concerns you have as I am here to help you.
You have Color Wheel Failure. Light engine must be removed to access and replace the color wheel. This page shows Samsung Color Wheel part number for different TV Models. This page shows Color Wheel Replacement service cost in Canada.
Sorry, the color wheel is only available in the Light Engine Assembly. You can not purchase it as a single part. You will have to purchase the engine and replace it to repair your TV. PN: 23405476 it runs about $450 with a $200 core. You may find it cheaper... I don't think it is readily available... Best of luck to you, I hope this was helpful.
Yes you can repair this your self it is the color wheel also keep in mind that if set does not play after replacing color wheel and lamp lights,color wheel working with all 3 fans running and set shuts off within 30secs of turn on BAD LIGHT ENGINE!!!!!!!! also they are NO LONGER Available cost of that part was 1,000.00
You have a bad color wheel motor. Its bearings are humming and the shifts in color are due to the speed of the motor changing. Obtaining a color wheel for these Toshiba DLPs is difficult. The manufacturer does not sell any of the most often needed components, color wheels, ballast boards separately form the light engine assembly resulting in a very expensive repair bill.
Call Toshiba. Maybe they'll have mercy on you and help with the cost of repairs.
YOU PROBABLY NEED A DMD BOARD. THE COST OF THE BOARD IS $900 . YOU CAN GET A LIGHT ENGINE FOR $700 THAT HAS A NEW LAMP, COLOR WHEEL, BALLAST AND DMD. WHAT A DEAL . THERE IS A $400 CORE ON IT SO YOU WILL HAVE TO SEND BACK YOUR NEW BALLAST AND LAMP TO GET THE CREDIT BACK. WHEN I GIVE A QUOTE ON THESE SETS FOR REPAIR MOST OF THE TIME IT EXCEEDS THE VALUE OF GETTING A NEWER BETTER SET. DON.
It could be caps around the power supply. If this is a LCD projection TV, it might be the color wheel.
I would call some TV repair places to see what they say. If it is a power supply issue, I cannot see it costing more than $50 to fix it. If it is a color wheel or something like that, the cost will be quite a bit higher.
