I have a samsung dlp when i plug it in i see the fan go on and also here a hum is that the fan or color wheel? andy way the lamp goes on and no picture. the lamp light is on in front. how do i know if it is the lamp or color wheel?

first, the color wheel should not operate if the lamp does not come on; if YOU replaced the wheel yourself double check something.

There are two cables from the color wheel, one is a typical plug and the other is a flat ribbon cable, the ribbon cable has connections only on one side as it plugs in: it is very easy to plug it in backwards in which case lamp will NOT come on at all.

I think this problem is coming from the color wheel here is the link

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.

Ok look my friend..

first i need to know what type of sound is it. like a click or a buzz?

and then here are 3 suggestions.

first clean your TV with some latex globs and a can of compress air try to do it really good try that...

second. check that all the cooling fans are working just fine!

last one. its your color wheel and you need to change it.

here is a link were you can find the part and not so expensive prices!

good luck!

Sounds like a bad color wheel. Generally when the color wheel goes bad, when you try and turn the TV on the lamp will ignite for a couple seconds and then turn off. It also makes a rather high pitch squealing noise.

www.Partstore.com should carry a replacement color wheel for your TV

That sounds most like the color wheel,
to change that you need to have some skill in electronics, I would recommend to take it to a shop

Hi, you have one of two problems, either the color wheel is going or one of the cooling fans are going, the color wheels are a very common problem in samsung dlp`s, sorry I can`t nail it to a specific part but I`d bet it`s the color wheel as they are notorious for failing in samsungs, video-tek

Yes a humming noise on that model is usually related to the color wheel It will get progressively louder

Sounds like the color wheel has shatterd, thats a fairly common problem with that model.
