Question about Sharp 56DR650 56" Rear Projection HDTV
I have a Sharp 56DR650 Tv and it is starting to hum loudly everytime I turn the TV on and does not stop. How can this be fixed? Thanks
I know this is probably to late to post but maybe it will help others currently having the problem. the loud noise is comming from the color wheel motor. it needs to be cleaned and regreased. it is very easy to do yourself as long as your mechanically inclined. if not then order a new color wheel and have it installed by a tv repair man if you have the money. you can find the steps on this website on how to remove the color wheel from the tv. I know becaue i have done it to mine and it is quiet and working beautifully. if anyone has any questions please feel free to email me and i will try to answer it to the best of my abilities. no i am not a tv repairman but i have been an electrician for the United States Navy for 16 years so I know a thing or two about electronics and I hate spending unecessary money fixing something where I could have done it myself. feel free to email me. thanks and good luck.

This is a follow-up to my 03 May 2008 posting. Cleaning the color wheel did not solve the humming noise problem. However, I now do believe the noise is coming from the color wheel. My guess is the bearings in the color wheel (or its equivalent) are going bad. My next step is to replace the color wheel. Sharp’s customer service however will not sell directly to its customers (I’m outraged)! Does anyone know of where to purchase parts for the 56DR650 HDTV?

I had the same humming on the 56DR650. I called Sharp and they sent someone out to my home to fix it from a TV repair shop. It was 2 years old and I had no extended warrenty. Sharp just fixed it for me. They were really cool and paid for it.

Ok, I just picked one of these babies up this past weekend. It was cheap, so I didn't bother with the research once i saw that it powered on and seemed to work.
It was sold very cheap because it was throwing codes, which the previous owner was told was a cooling fan. Due to my computer hardware experience, I decided to trace what the problem was. The 2 accessible fans were working flawlessly and silently, the 3rd fan (going to the input components) was stopped due to dust bunnies. A can of air and a complete cleanout solved all issues with the cooling fan codes. The loud annoying hum is the motor that turns the color wheel. Since I had everything out of the TV anyway, I decided to trace the sound which is actually behind the color wheel and sounds more like a bearing or mis-balance in the spinning motor. The color wheel itself is in perfect condition.
In the meantime....annoying hums are fixed simply by turning the volume on your tv or sound system up - it's barely noticable during normal operation and is only really annoying when initally turning it on.
Hope this helps someone.

After a few tries, Sharp customer relations agreed to pay for the replacement color wheel part at an authorized Sharp repair shop. Labor is at my cost. As previously described, the TV is 2.4 years old and out of warranty. I first tried e-mail but got what looked to be a generic reply telling me to call customer service. My first call to customer service was not satisfying at all. After a few holds I was told there was nothing they could do for me or offer me (after they rejected paying for the part, they also rejected giving me any rebate or discount on a new TV). The last call was made by my wife on a different day. She got the same answer that they couldn't do anything from the first person. She then asked to speak with someone else who could possibly do something. After some convincing about the obviously faulty problem and an argument that who would ever buy another Sharp TV if the last one only lasted 2 years, they agreed to pay for the part. They faxed a memo to the repair shop and it is now being repaired. Thank you Sharp.

I had this exact same problem. Fortunately for me, Costco extends the manufacturer's warranty for an extra year, so they will fix it up to 2 years after date of purchase. I found this out on 8/12/08, and I looked up the purchase date, and it was 8/13/06! What luck!!! I called Costco that very day, and they got me in the system so I was still under the warranty (barely).
So they got a tv repairman to come out, and he determined the problem was the COLOR WHEEL'S MOTOR. He came back a week later, swapped out the motor, and now it works perfectly with no noise at all, and no cost to me!

The noise you are hearing is most likely the color wheel. The easiest way to check is to run the set and unplug the brown flat wire to the color wheel, if the sound stops its the color wheel.
If this is the case, I have them available and its cheaper then changing the optical engine.

Same problem with my unit. I just changed the fan and that did not help. Powered up tv with back off and can hear the noise
from the color wheel. Same sound as others described above.
Hope I can locate part somehow or may try to remove and inspect for problems.

Well, purchased tv 12/31/05, by 3/1/06 tv was humming loudly. Under warranty they replaced the light engine. Now 12/07 it's at it again. It would be the third part in 2 years if I could afford the expensive repair. Repair would be 1.5x the cost of the TV originally. Time for a smaller LCD for over the fireplace. I am going to try to go to the Sharp Corporate office in Mahwah, NJ. Their phone number is 201-529-8200. Ask for the Consumer Electronics VP office and file my complaint there. They know about the issue. Whether they do anything is another thing. Customer Service won't do ANYTHING. But that's expected unless they were authorized by MGT. If enough of us that have this POC TV will hassle them maybe they'll do something. Good luck everyone.

You need to replace your lamp fan. The bearing is wearing out. Fan cost about $95. Here is URL to purchase fans. http://www.partstore.com/Model/Sharp/Sharp/56DR650.aspx

It is the color wheel. A fix can be found at
- at your own risk, but if you have the time & littleknow-how it can be done. The option is replacing the color wheel - which costs more than the set in the first place! ~~KO

Mine did this too starting 11 months ago. I think it is the color wheel or something. It still worked except about 2 months ago it started getting louder, and then it started not turning on when I pressed power. The power led light would just blink 3 green times and 2 red. I would have to unplug it then plug it back in and eventually it would turn on. Starting 4 weeks ago it stopped turning on for got. I'm currently waiting for fry's to replace my tv (I have a warranty), because sharp doesn't make the part they need to replace so frys finally decided they'd have to give me a different set. So the solution as I know it is to hope you can return it or have a warranty because there's no replacement parts for this tv anymore.
