Question about Toshiba 52HM95 52" HDTV Projection Television

1 Answer

Toshiba TV humming

I've seen some other posts related to a Toshiba TV "humming". Some say it's a fan, others say it's the color wheel. One is about $300 with labor (fan), the other is about $800 plus labor (color wheel), because they have to replace the whole light engine, not just the color wheel part.

I think this is totally rediculas for a TV that could be bought today for about $1000 or so. Is there a way to ask Toshiba for some assistance?

I've had the TV for about 30 months, so if I bought the extended warranty, I'd still be covered. But should I really pay $400 for extended warranty for a TV costing $1800? If the issue costs about $400 to fix, then I'm even. So if it's the fan, then I'll just pay it and *******. If it's the color wheel, I think that's terrible flaw in a product or service.

Just asking for some assistance/direction.

Feel free to email me at with any suggestions.

Thank you,

    Thanks for the feedback.

    Per your recommendation, I turned on the TV, and the humming started. I let it run for about 3-5 minutes, and then turned it off. The TV has always taken about 5 minutes to "cool down", and then completely shut down. I've never considered this an issue, because, as you stated, the fan should probably run to cool down the unit.

    Well, after turning it off, the humming continued. So, from what you stated, I probably have a fan issue.

    Here's where my next issue comes in - I was given an written quote by an "authorized Toshiba repair technician" of $750 (the previous $800 was an estimate over the phone), and it states that it is the light wheel causing the issue, and I have to get a new light engine.

    I wasn't here when the technician was, so I'm not even sure if he opened up the back of the TV to confirm what was wrong. I'm thinking he turned it on - listened, and then said "it's the light wheel like so many Toshiba's before" and wrote me the quote.

    I think I'm going to call the technician company and ask what was done for them to come up with the estimate. I'm then going to call Toshiba to recommend some other tech company.

    How can I find "Tri-State" to ask about the rebuilt color wheel? If that's the route I eventually have to go through.

    * Also not sure why there is a series of ***** in my first comments above, I did not put anything inappropriate?

    Thank you so much.

    I have a Toshiba Theater Wide HD rear projection with the same issue. It has a high pitched whine or humming constantly. Not such a big deal if watching television but when power is off, it still makes the noise. The only way to get the noise to stop is to unplug the darn thing. So how can you tell if it is a fan issue or the color wheel?

It's really your call on the extended warranty - obviously I don't opt for one on any of my home electronics but I have taken out a policy or two on appliances. (I don't repair them)...
Like most averages something may never happen to the unit. That's how the warranty company makes their profit. But if something does then you have that piece of mind knowing that you're covered... (As a footnote I should add ONLY if you purchase a plan with a reputable warranty provider. There are MANY providers that I would NEVER do business with regarding extended warranties.)
I have been in MANY homes where the people were simply ecstatic that they had opted for the extended warranty. And on a four year old Tv the repair came to more than the Tv was worth..
That Toshiba you have there turn it on and listen to the hum. Turn the unit off and pay close attention to what the hum does. If the sound stop readily it's probably the color wheel. If it's still there for several seconds it's probably the fan. The fans are designed to remain running for several seconds after the power is turned off to help with cooling..
You might find a reputable shop locally and ask about the option of having the color wheel rebuilt. Tri-State module rebuilds some color wheel assemblies, and if they can do that it will be at a fraction of the cost of a new one...
Good Luck!

    I'm not sure I understand about you calling Toshiba for the estimate, is this a warranty issue? Toshiba will often times recommend replacing the LE but it doesn't sound to me that it's necessary. If the sound continued after the set was turned off it's likely the fan - not the color wheel. That said, I've never had to replace an LE if the wheel was bad they are separate and distinct components. Just finished an LE replacement for Hitachi on their dime (warranty) and it was billed out at $1100.00 dollars just for the part and $400.00 in labor is what I charged. But Toshiba's are usually a bit cheaper.

    Tri-State Module is their front page has a picture of a color wheel assembly - one heck of allot smaller that the entire LE... However, as I was answering this I went through their site and they don't yet rebuild the Toshiba line.

    Personally I'd contact a NESDA qualified tech in your area - it doesn't sound like it's something you're prepared to undertake repairing yourself - - you can be assured if a Nesda tech says it needs to be done - it needs to be done! will get you to the search site..

    Good Luck!

I own a toshiba 62hmx85 tv and had a frequent humming sound coming from the tv, technicians told me over the phone that it could be the color wheel going, soon after that the tv stopped working and all i...

The color wheel on this set is not available. First thing I would do is replace the lamp. MCM electronics has a Philips for $99.00. The hum could have been the lamp fan which is common on these sets. There is a kit from Hitachi the includes some rubber dampers. What I commonly see on these sets is when the lighr engine is going bad(this is where the color wheel is) the color gets a green,bue or yellow tint and trhe picture may get dim. its rare that the color wheel stops working on this model. Call adifferent tech for sevice. Anyone with experience on these sets will know whats up.

It is either the color wheel or a fan. To isolate the color wheel, remove the back cover and make sure you put the lamp door back on so that the door interlock switch is activated. Turn the set on and get the picture and humming noise going. Just to left of the rear fan there are some wires. One is a really flat brown or rust colored ribbon cable that plugs in to a board on the left of the wires. This is the color wheel ribbon. When you unplug it the set will keep going for a moment or two but if the noise stops, you will know it is the color wheel. Don't be alarmed because the set shuts off with this ribbon disconnected. Just let all the fans stop (for proper cooling) and then unplug the set for 5-10 minutes. If the humming did not stop you have a bad fan motor. Plug the little ribbon back in while you have the set uplugged. Plug the set back in and turn it back on and try to isolate which fan it is, if it is a fan. If you determine it is a color wheel, the light engine will have to be replaced as Toshiba does not offer just the color wheel. If it is a fan, those can be replaced. I hope this helps. Let me know what you find and thanks for using fixya.

Our TV is making a loud humming noise. We think

It's likely your color wheel rather then your fan. I've replaced quite a few of these and the fans are usually good. Get and estimate - I generally charge $250-350 Total
also google your model # and color wheel to investigate further.

I have a 44 inch 44nhm84 DLP. When the TV is turned on, it makes a loud humming noise that goes down in intesity twice and then finally a lesser humming noise after the picture comes on. At first I thought...

This does sound like a color wheel. To my knowlege, Toshiba does not sell the Color Wheel seporately. In short, you have to replace the Opical Block. The cost of this is very exspensive and Toshiba may not sell it to you. You may have to go through a Toshiba Service facility to obtain it. Check prices of new LCD sets before investing the money.
Hope this helps,

Humming noise

There are only two moving parts in this set. The fans and the color wheel. Typically when the color wheel starts to break or go on the fritz, the tv stops working. Count your blessings you've still got the picture. Open the back and turn the tv on. The color wheel is located on the optics block tray. The fans are very visible with the back off. Stop the fan for a second and see if the sound goes away. If not, you might want to start looking around for a replacement color wheel. is a good place to start. Sometimes carries them too. Be aware that there two different wheels available. If the fan is the culprit of your problem. Radioshack will likely have a replacement for you. If you need further help, post a comment or email me and I'll send you pictures of what to look for.
Good luck.

Sporadic Hum on HLP4663W

I would guess that its the fan for the lamp, as the color wheel will power down as soon as the power is cut. the cooling fans will continue to run

I am wondering if this sound might be your color wheel spinning. The color wheel often makes a low humming noise as it spins. Try checking to see if this is not the source of your noise. You need the color wheel to generate the colors needed to turn the B&W picture generated by the DLP into a color picture.

Thank you,

Loud noise

I believe it is the color wheel. The motor might be going bad or it has dirt or dust in it.

Toshiba DLP fan noise (52hmx95)

i constantly hear complaints about fan noise in dlptvs if you sit in front of your computer you will hear the same noise even in the next room there is no solution to the fan noise problem this product has a huge cage fan and a second and third three inch fans in it.... more than the samsung product it can be noticeable if the tv is on hard surfaces ie wood floors ,inthe corner, glass top etc the vents on the back of the tv allow for proper cooling of the lamp at shutoff so it doesnt shatter the tube its kinda like annealing glass its designed to extend the life of the lamp .... which im sure youve priced call toshiba and tell them your lamp is bad right now and get a new one for an emergency ( warranty if you can do it ) they are also improved this product is known to have short bulb life sometimes the zinging noise you hear is indicative of a bad color wheel in the light engine which would require replacement ( not cheap) toshiba will not piece out the color wheel assembly individually
