Question about RCA D56W20 56" Rear Projection Television

1 Answer

Great pic but bad sound

If the sound setting is set to automatic or stereo, all of the lower chanels have a loud buzzing noise and the higher chanels have it off and on. the right speakers have the buzzing noise no matter what setting. Called a repair place and they said something about an amp? If I knew what part is bad and what it looks like I can remove and replace it. Help

Re: Great pic but bad sound

Your problem could be the main amp board, the signal panel or the audio processor board. You will need to get a service manual for this set to diagnoise these problems. Good Luck

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.

My samsung 42 inch hdtv is making a buzzing noise

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.

I have a Samsung rear projection tv. It has been

The Lamp probably is bad but it going bad would not cause a buzzing sound. I have a hunch that the Color Wheel Motor is bad causing the buzzing noise. It is a major repair and the cost would be expensive. But this is the deal, you will need to get a qualified repair person out to confirm the symptom to be sure. You can go ahead and replace the Lamp to get the set working again and use it for as long as you can stand the buzzing noise. If it is the Color Wheel Motor, I would check prices on replacement sets just to get a feel of how much you are willing to spend for repairs.
I hope this helps,

You have bad capacitors in the power supply that took out the regulator, or the ballast circuit is defective. Not really a repair for the novice. Good Luck
