The color wheel is the most common problem when it comes to noise from DLP's. To determine if it is a color wheel or fan: Turn on the set. When the noise starts, turn off the set. If the noise goes away within 5 seconds, then the color wheel is bad. If the noise goes away after one to one and a half minutes after the set was shut off, then one of the fans are making the noise.

SOURCE: Toshiba DLP fan noise (52hmx95)

UUUUggggghhhh I have a 1 year old Toshiba 50" DLP rear projection and it had fan noise. It also had a wierd dark spot on the screen that really wasn't on the screen itself. I was taken to a service center and held captive for 2-3 weeks and returned with a new light engine. I thought great! 3 weeks to a month later and bordering on expiration of warranty it starts to make a low screeching sound like a small motor in need of lubricant. The picture jumps all over and resembles a 256 color PC Monitor. The service center comes and picks it up and holds it captive for another 2.5 weeks and says they cannot duplicate the problem. I had even sent them a quicktime movie of it in action.
They drop it off and an hour goes by and off she goes again. Now the longer I leave it on the worse it gets and shuts itself down and sometimes blinks the "light engine" code. Spoke with Toshiba and they are escalating it and should hear back in 3 days... OMG. Kinda off on a tangent, but they do make strange noises.
Did Toshiba get out of the DLP game???

SOURCE: noise from tv

I had the same problem with a 5065. I purchased and installed a new color wheel and that solved the noise problem. The color wheel has a bearing that gets "dry", and when it fails it does sound like a fan bearing.

How do I fix loud humming noise in my DLP HLP4663W 42 IN Samsung TV?

I would start by checking all the cooling fans to see if one is dirty or possibly failing.

I have Samsung DLP TV 50 inch HL-P5063W

First thing to look at is the color wheel this model uses--usually it will make a high pitched fan like sound but can make a grinding sound also.

If it slows down from the 12,000 or so RPM speed it will cause color issues.

Toshiba model number 62HM95 62' makes grinding noise

SORRY, This is from the authorized Toshiba parts center:

"The color wheel, lamp fan, lamp fan holder are parts of the LIGHT ENGINE only." It means the wheel is not sold separately and there is not even listed in the breakdown for the set a part number.

A replacement light engine (optical light engine) retails for 456.00 list and is sold on an exchange basis only.

No picture, siren type noise as restarting

My Toshiba dlp 62hm116 was used for 3 months then stored for 2 years, I turned it on yesterday and it makes a loud grinding noise which I think is probably from the exhaust fan area and the picture is black except white at both vertical sides. It worked fine the last time I used it 2 years ago. Any ideas?

Tv making noise sounds like projector motor.

Your cooling fan may be collecting lint. If it cannot run freely, you will lose a projection lamp. Just like a clothes dryer, you must have a good clean exhaust exit to assure proper performance!

Cooling fan motor is making loud humming noise

You will have to pull out the light engine. That will consist of 4 or more screws and disconnecting some plugs. The the whole unit slides out where you can get to the fan housing.

Unless you're mechanically inclined, you should not try it as you could damage the assembly.

I don't know the part number off hand and some of those have newer part numbers as replacement for the original. Just do a google search to come up with a part number.

Samsung DLP HDTV wide screen

Sounds like the colorwheel (used in DLP projection sets with a single DLP panel) is going bad, either the wheel itself or the bearings on the motor driving the wheel are starting to fail. I would recommend getting a professional to service the TV set.
