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.

Samsung model HLP4663WX/XAA with loud buzzing noise, need to know which part to replace.

See attached photo: you have a bad color wheel----it turns at about 12,000 rpm and bearings in the tiny motor go bad.

High pitched or fan like sound is classic symptom.

The wheel is available on the internet and You Tube has video instructions by model number for replacing it---Google the model number for the part number for your set to locate the part and instructions.

This for most people is a do it yourself job---takes like 45 minutes start to finish.

If color wheel slows too much set will shut down as its speed is monitored and the wheel can even shatter causing shutdown of the set.

Replced convergense chips, 2 copper ring pull off board, installed tv powers up then shuts down. Can hear a klicking noise when powering up & one when it powers off. reading a 22 code?

the rings that lift are what allows the ICs pins to be soldered into the circuit if the rings have lifted or are missing the set will not operate. It sounds as if you have a Mitsubishi with the 22 error code. Fixing the rings that lifted and double checking the pins to be sure none are bridged together with solder.

My washing machine stops half way through the cycle, and makes a ringing noise, I think it stops just before the spin cycle as it is full when it stops.

Possible that the drain pump is faulty and it is clogged with fabric dirt and so as it tries to spin and drain you hear the noise but since the water does not drain the controller unit shuts down as a an error.
So manually lift the drain and clear the water, then remove the drain pump assmebly and open to clear the dirt , refit and check.

There is no picture when I turn the TV on, the red lamp light under the power button is blinking, when you turn the tv on, it goes off for 60 seconds, there is a ringing buzz every 20 seconds, then the tv...

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is xl-2100 you can find it here: a blessed one!
