This is usually located on the light engine if you go to the link below and zoom in on the picture you can see it right above the ballast. It will be a small circle about the size of a quarter with a small board on top.

Maybe your color wheel

Do you know for sure it is the color wheel??
If so, have a honest & reliable TV tech change it.

I would not fix it, have you (not indicated here) tried to unplug set for a while?

Replace the Color Wheel.

Since Samsung only has them online for authorized service centers you can try to Google the model number for "service manual" or tell me what problem is and what you have tried.

This sounds like a very common issue.

If set is hard to turn on (takes several tries)but will eventually turn on hereis what my guess would be.

Every set has a standby power supplythat is running 7/24 if the set is plugged in and it supplies voltage to theremote circuit that turn on the main power supply for the tv and hence turn theset on.

This is an area where companies cut corners by using lower rated voltage caps.By this I mean Standby usually provides under 10 volts to trigger the seton----what they do is use filter caps rated at say 10 volts max in a circuitwith 9 volts (example)=with the standby on all the time the filter caps(electrolytic caps) dry out and fail.

The problem usually begins where you have to turn set on or or two times andgradually gets worse--takes longer and more tries to get it to come up.

Once on it will stay on until turned off for a period of time.

The caps will begin to work better (regain some of thecapacitance) as they get hot--hence one it is on it will seem ok.

The beauty of this problem is most of themhappen when set is a year or two old (no warranty) and all you have to do islook at the top to locate bad ones.

They are generally black or blue and round and vary in --they have twoconnections each--a + for positive and a - for negative--not unlike a batterywhich in a way they are. The + and - are marked on top and bottom of most boards.

They are easy to replace and not expensive parts.

The tops are silverand metal looking with creases on top and if bad they will be puffed up ontop---tops must be perfectly flat with no brown material leaking top or bottom.

If this is your problem once you id them (make a drawing) you can begin.

Here is the critical part---on each cap is also marked the value like 220uf 10vdc---220 micro farad at 10 volts maximum.

If you find for example 6 puffed up and all are 10 vdc replace them with thesame value capacitance (like the 220 uf) but go up to at least in this case(from 10 volts) to a 16 or higher rated voltage cap.

The only issue is when you go up in voltage rated value the cap is larger sosometimes there is an issue of physical space for the replacement on the boardto fit them in.

The reason they cheapen these sets in this way is if 10 caps and you make25,000 sets there is a considerable savings in parts cost.

They do not care as long as it lasts past the usual one year parts warranty.

I have taken the time to be long winded because this really sounds like it maybe the problem you have.

See attached photo of a typical cap and if you have questions or need advicelet me know.4_6_2012_3_10_32_pm.jpg

Look for puffed up caps on the power board that look on top like this.

Provided that your lamp is not reaching the end of its life, there have been some issues with the lamp door switch opening due to thermal expansion of the plastic. I would bypass the two wire switch altogether to eliminate this possibility, it won't affect the operation of the TV. If the set still shuts down, and there is no on screen display mentioning a fan failure, replace the lamp. Part number is listed on the lower left side of the TV with red label.

Hi,
It is safety switch, however you can bypass it on temporarily to test tv.
You need to solder blue and white wires with little wire to make connection as shown in below image, check red line to solder extra wire to make connection.
Hope this will help you.
Thanks.

It is probably caused by the wrong systen video. Maybe S Video into a Composite video input.
Check your cabling and system settings.
Hope this helps.

Now u turn on the tv u hear alots of clicking too?Yes.The ballast board is also dead.The ballast board job is to help to ignite the projection lamp.

Samsung HLP5674W... | Answered on Oct 26, 2010


Loud sound would be coming from defective color wheel that is mounted i light engine, next to lamp housing. Replacement of color wheel is required expertise/ experience and professional will do that for you in correct and in safe manner.
Contact local tv repair shop to get color wheel replaced in tv.
Thanks.

I have not been able to get a part number from my normal suppliers as it is not listed. I would suggest that you call Encompass parts directly at 866.779.7421. They should be able to provide you with the part number and cost.
