Replaced lamp, would not come on , Got a loud, low pitched buzzing noise.

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.

Could be a slightly loose lamp connection and/or slightly loose lamp module - especially if you
have big trucks or railway tracks near your place (like me). Try powering down the TV set, use the
instructions that came with your TV to remove the lamp module, then simply re-install the lamp
module (also known as "reseating the lamp module").

If the buzzing noise persists, then
its coming from a component near the lamp (such as the power supply).
If there's a transformer in the power supply that's buzzing, then its about to fail.

First. The whirring or buzzing sound you hear is the Color Wheel and it needs to be replaced. Second, since I do not know when and if the original lamp has been replaced it is a good idea to replaced the lamp. The bad Color Wheel is the one causing the set to shut down.

It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

Hi! have tried replacing the ballast?

Hello,

There is a fan beside the lamp chamber in this TV. There should be 4 fans total, and the one beside the lamp chamber might be making some noise. They are all bearingless fans, so the noise should be relatively low-pitched "whirr" if it is the fan. If the noise is more of a buzzing sound, it could be coming from the lamp driver (ballast) or from the lamp itself. Lamps tend to do strange things toward the end of their life.

If you have never changed the lamp, it is about time. They have a 2.5 -3 year life span with average use.

One thing you can try is to turn the TV on from a cold start, and watch inside the vent areas beside the lamp chamber. If you hear the noise before you see the lamp light up, then it is probably a fan. If it starts as soon as you see the lamp light up, it is the lamp or ballast.

Hope this helps you...

What is the make an and model of the set?

Is the buzzing from the speakers or from inside of the set?

Is it a high pitched frequency buzz or a low pitched frequency buzz?

There are many things that can cause a buzz in a TV set. In anycase, the set will require tech service.

sounds like the color wheel needs to be replaced very easy repair on that model Samsung.

Is this buzz from the speakers?
Is this buzz from the set itself when the sound is turned down?
Is this buzz a low pitch sound?
Is this buzz a high pich sound?
Does this buzz vary in loudness with the volume control?
Does this buzz change in level from time to time?

You should post the details and the circumstances of use in order to give some idea of the conditions.

since you changed the lamp my next thought is that the color wheel has failed,,,most good road techs can replace it in the home..the cost would be between 220.00 and 350,00 depending on the company...
