The color wheel is the first item that should spin when power is pressed. It could be the color whel. I hate to guess as you could end up spending money needlessle. I suggest you go to the link I am posting as they have the trouble shooter manual for 29.99 and they will email it to you and it takes you step by step to explain what the problem is.just click on HD50LPW175 in the RCA section and thats the trouble shooter for your model. Cause I hate to say what it could be cause that could cost alot of money buying parts that you dont need. Heres the link.

HI. Would you have the best picture wizard set up settings for an Lg47lm640t-za tv please? Thanks, John


Use your eyes to determine quality; only they really know. FYI, when determining the best color and tint, when you view the setting, think to yourself, "do people really look like that color in real life"?

About a week ago I replaced the lamp in my samsung hls24266 with no incident. Now when I turn the tv on, I hear a very loud humming noise. I tried disconnecting the coaxial cable but it does not go away....


I can't explain the timing of your problem and why it showed up after lamp replacement, but Samsung color wheel failures are usually associated with a rather loud hum. I would removed the back, jumper the lamp door switch and try to determine exactly where the hum is originating from. I think you'll find the color wheel is the culprit.

High frequency noise


Hi. The most common cause for this is the color wheel. Replacing it requires removal of the engine/optical block. I'm not sure of your level of expertise but if you want to give it a try go to this website: http://www.jangro.com/electronics/samsung-dlp-replace-color-wheel/ It'll give you some idea of what you're up against. It is similar to what you'll have to do but I don't think your chassis is exactly the same as this one so some things will look different inside.

There is a whining sound upon powering up my HL-P6163W which softens after about 5 minutes, but doesn't disappear completely. I think the source is either the color wheel or the cooling fan. How can I...


It the Colors wheel,cooling fan will shut down,if it start making noise to the fan,because the whole projection egine and the bulb link to it.The fan have to run a certain RPM to keep the tv running without problems.These colors wheels run 1000 RPM to start to give the tv colors and it make out Flexy glass and plastics.What ur opinion,who will give u the problems,first as parts wise.Ok any noises like whinning in the tv alway the colors wheel starting to buckle and warp.Getting worse make motor noises and briddles enough will brake and shatter it into ten of hundred of pieces.Who know,than inside what else will cause the rythum of the RMPS running of the tv,when u replaced it.

Have the color wheel replaced on this unit, The high squeal is the color wheel bearings gone bad. Fortunely on this unit it can be replaced with out purchasing a entire optics engine assembly. The unit will not ignite the lamp until the color wheel has gotten to a pre-determined speed. Around 9600rmp, if it does'nt then the ballast will not get the signal all is well and ignite the lamp.

My tv is a samsung dlp. i have determined that


most of the time you just need to replace the color wheel; the jumper they are talking about is on the DMD board which is a metal box attached to the light engine---if the jumper needs to be removed you will have a working set but the color will look odd--usually missing blue or red---it is a small two wire plug with a jumper and can be removed with a hemostat or needle nose pliers.

If you buy the color wheel I have specific instructions that you will not find on line to avoid problems when you replace it--lots of people think they can do it until they try and fail.

I would try the power supply first as the ATC336 has a history of the bad power supply boards.If the power supply doesnt fix it then I would think it may possibly be the ballast
