I would have thought not but it is your choice.
Is the optical engine OK eventhough everything has overheated?

Loud buzz/whirring noise, need help diag and fix


If Samsung the color wheel (part number BP96-01579A) is suspect number 1.

Wheel turns at over 8,000 rpm and commonly fails= High pitched sound or fan like sound---and when it fails (shatters) you will have a grinding sound and set should shut down.

There is an easy way to know---with owner manual remove the lamp unit (its a cartridge) and look where the lamp faces--if pieces of the wheel are missing etc the wheel is gone.

Most of the wheels are customer replaceable if you are handy. You Tube even has video instructions for most models for this repair--most sources that sell the part also provide instructions--for a first time person doing this it takes around a hour.

see attached photo of typical color wheel.

I've a Samsung DLP Model HLR-4266WX that has started to hum and is distorting the picture. I've replaced the cooling fan on the heat sink in the back and that didn't work. Is there another fan in the set...


Color wheel would be cause of hum noise and distorted picture on screen.
Please note that color wheel is not user level repair and requires expertise because it is located in light engine, the most sensitive and expensive part of dlp tv.
If you are good with electronics stuff fix then have service manual copy in hand to start inspecting color wheel.

After 10 sec. after start up the tv starts to make a large growling sound for about 5 secs. then repeats every 15 sec. sounds like if might be a fan. How many fans in this t.v. . Took the back cover off...


That growling sound is most likely a your color wheel. Often, a color segment breaks free and causes the wheel to become unbalanced. I would suggest searching for a tutorial or "How-To" on replacing it. Basically, you need to disconnect (about 4 connections) and remove the Light Engine (2 screws). Then pull the cover off the color wheel housing (to the left of the lamp, 2 screws). Disconnect and remove the color wheel (2 screws and 2 connectors). You will need to use a vac the glass out from the lost color segment(s). Here's a tip for reassembly: color wheel 4-wire ribbon.. copper on the connector should face you. Also, the lamp door switch must be tripped or the TV will not fire up. I hope this was helpful.

I own a Samsung HL-R5067W 50'' DLP. Set is about 3 years old. Recently I heard a loud pop while viewing, picture distorted, but never went blank. I turned set off. When turned on again a loud whining noise...


Check your color wheel. There is a DIY guide for replacing the color wheel. Mine did the same thing yours is and my color wheel was all busted up. Unfortunately after replacing the color wheel my set continues to do the same thing, but this could mean I need to replace the ballast as well.

I have a model #hln5065w 50'' DLP TV. How do I know if the cooling fan is bad vs. the color wheel? Are the symptoms the same?


No the symptoms are not the same. If you hear a lou whine or buzzing or see the color fluctuating or no color then it is the Color Wheel. If any one of the three fans are bad you will see a CHECK FAN# on the screen. Fans on these sets very rarely go out. The Color Wheels will fail before a fan will. Color Wheel part# is BP96-00250A.

Cooling fan is loud . I'm going to replace the lamp in the unit because all 3 lamps are blinking on the front panel. Unit shuts down but I'm wondering if there is a seperate cooling fan in the back of the...


That's probably the Color Wheel you are hearing. When you turn the set on the color wheel has to run, one of the several things that has to happen for the set to come on. The color wheel sends a signal back to the control circuit to tell it it's running. If these sets fail to light the lamp they will shut off and try again, that's why you hear the color wheel start then wind down then start again. The set should try three times before it decides it's not going to be able to turn on.

One way you can tell the difference in the fan sound and color wheel sound is if you can get the set on, let it run for a little while so it gets warm, then when you turn it off the color wheel will start winding down but the fans will continue to run for a minute or two.

SQUEALING NOISE AND SET TURNING OFF


The squealing noise is a defective color wheel. When the color wheel does not get up to speed (or stay up to speed) the set will shut down with the blinking you describe. You need to replace your color wheel or have a tv shop replace your color wheel.

Trying to replace lamp fan


First let make sure it's the Lamp fan. What many people think is the fan, And by the way there are three fans in this model, What sound like a fan is in fact a color wheel. So listen to the set as it starts up, these Samsungs make certain sounds when they start. First after you hit the power button you get the "Samsung Tones" from the speakers, second ALL the Fans start 1 to 2 seconds later the color wheel starts then stabilizes, third you may here the lamp fire. So if the sound takes two to three seconds after you turn the set on it's the color wheel BP96-00250A Now when it shuts down its like this First the shutdown "Samsung Tones" then watching from the back after a few seconds the lamp will shut off, then the color wheel stops but all the other fans remain on for about 2 minutes. I've worked on thousands of these and in only one or two was the problem a fan. but on the other hand I have enoghf bad color wheels I was able to make a pertty inpressive Christmas decoration
