Question about Samsung DLP HL-P5663W 56" TV

2 Answers

Have a loud high pitched humming noise coming from my Samsung 56" DLP # HLP5663WX/XAA. Ruled out Fan #'s 1 & 2. Can't find fan #3 or color wheel. So it is most likely one of these items. How do I find good instructions or video on locating and replacing these parts? I am pretty handy and can fix just about anything. Any info on this problem would be appreciated. Thanks.

    Start to finnish, changing the color wheel will take 1 1/2 - 2 hrs to replace. Best advice I can give is give yourself plenty of work room behind the TV. Use some little cups or an egg carton to keep screws seperated. A hand screwdriver is best for most all the internal screws. All are #2 phillips head. If you have ever replaced the lamp, the color wheel is a little deeper inside beyond the lamp housing. Keep track of all your parts. If you have compressed air available, carefully blow the dust from everything as you pull it out. Search YouTube and you will find a good tutorial there.
    Color wheel will cost about $110. Paying a tech to replace it for you will be $200 . It's not really that difficult to do yourself. Just time consuming. Be happy when you are done and have no left over screws.

A few things to look at:

1. When on does set have normal brightness (lamp if dim) and I would also remove the lamp and inspect it--look at the glass pillar inside to see it is not bent from heat.

2. With the lamp removed look where it faces at the color wheel, no missing segments or the set when on does not have a high pitched or fan like sound. If the wheel is turning too slow for any reason the set will soon detect that and shut off.

Typical color wheel:

It is a DLP type set and if lamp comes on but other issues, I would first remove the lamp and look at the color wheel that faces it---looking for any broken or missing segments----often but not always the wheel will produce a fan like or high pitched sound as well.

It is much more likely considering all these the wheel fails to be your issue.

The problem is often described as a fan like or high pitched sound which since the motor on the wheel turns at over 12,000 rpm is likely to be the cause.

Hint: most color wheels if you listen from the rear when the set is shut down the whine/fan noise instantly slows down until the wheel stops.

Eventually wheel will seize up and shatter and set will not come on.

Wont turn on loud ossilating humming lamp light blinks for a few minuits then all three lights blink

YOU may have a bad color wheel, it is very common. The wheel will before it fails produce a loud high pitched sound and or a grinding noise.

The wheel turns at 14,000 RPM and they frequently fail.

if the wheel is shattered the set should not allow the lamp to come on (you should be able to look behind the set and see if lamp comes on for even a few seconds)

See attached photo of color wheel used in some of these sets; if it is the problem the internet not only offers them for sale but there are video and written instructions for customer replacement of this part.

If this has told you something you did not know rate this solution as very helpful as I do this here for free.

Loud noise and no picture ON DLP model HLR5668WX/XAA

If it is a high pitched whine or a grinding sound it is a bad color wheel.

Not real difficult to determine and replace.

My Samsung DLP is making a loud humming noise

Most likely if you are hearing a fan like noise from this DLP it is not the fan.

These sets use a replaceable color wheel that before it fails makes either a high pitched whine or a fan like sound.

Part is usually customer replaceable and there are free written instructions and video instructions on YouTube for most models.

Toshiba 56HM195 56 in HD DLP Loud Buzzing and color distortion

If the sound, sounds more like a Hum with some vibration chances are the Cooling fan located behind the lamp is going bad, about $20 to repair, if its a high pitch hum most likely the Color Wheel and if thats the case about $30.
Good luck, my fan just went bad now seeing green dots everywhere, so debating on just junking it out or fixing it, with winter coming on might just breakdown and buy LCD and say the heck with DLP from now on.
Good luck to you..
