Your picture processor is broken. we have the same tv, after 1 year problem started. we got a tv tech out and he looked at it and said it would cost $1800 to fix and this is after we bought a $400 bulb from sharp. this problem is in many of the same tv's of this exact model as we've invstigated and sharp is unwilling to help. there should be a classaction suit or recall for this exact tv.do not buy bulb , it will not work

Make sure lamp is in correctly and as far as the color wheel: The ribbon cable from it to the DMD box only has connections on one side where it plugs in---it is possible to put it in backwards and set will detect wheel is not working..............

Samsung dlp tv HLP5663W makes loud noise


Yes, the set uses a color wheel and the lamp faces it.

The wheel turns at over 8,000 rpm and is well known for this problem=bearings in the tiny motor go bad.

The high pitched or fan like noise (classic description) is this part.

Sooner or later the wheel (plastic colored segments) will shatter and set will shut down lamp and not operate---set monitors the speed of the wheel so if it slows down or stops it knows.

The part is readily available on the internet (Google the model number with "color wheel").

This can be a do it yourself repair and You Tube has video instructions for replacing the wheel by model number.

There are two common pitfalls to avoid which the instructions that come with the replacement part usually do not mention---if you decide to do this repair let me know and I will explain.

Where is the lamp module located for a sony kdf 42we655?


Please read here: http://esupport.sony.com/US/perl/news-item.pl?mdl=KDF42WE655&news_id=84

From SONY:
If the screen becomes dark, the color looks unusual, or the LAMP indicator on the front of the TV flashes, it is time to replace the lamp with a new one (not supplied).

Use only a replacement Sony XL-2100U or XL-2100 for your TV. Use of any other lamp may damage your LCD projection TV. Contact your Sony dealer for a replacement lamp.

Click here to download step-by-step directions for replacing your TV's lamp.

Note: Before replacing the lamp, turn the power off on the main unit. Wait several minutes, then unplug the power cord. (The cooling fan will continue to blow for about two minutes after turning the power off.)

Be sure to allow the lamp to cool down completely before removing it. The surface of the lamp remains extremely hot for at least 30 minutes after the power has been turned off.

At start up TV makes siren & ratching like sounds, no picture screen dark, requires turning TV off, is this cooling fan or color wheel problem & lamp replacement or all


That could be any of them. If you can get access to an analog meter such as voltmeter, you can test power to the cooling fan, to the color wheel, and to the lamp. See if any or none are getting power.

Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.

Samsung DLP HLR5668W has mostly dark picture + grinding noise


Pix looks like a light pipe issue, inside the Light Engine. as far as the shutting down, could be a bad fan causing the grinding and when stopps the DMD turns the set off.
