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

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

Hello why do I have a loud buzzing noise coming from my umc combination 21 inch television so bad you cannot here program dialogue ?


You need to send your TV Model first, but in general any strange sounds in a TV come from the followings:
1- High ripple in the power supply of the sound card.
2- Bad polarized capacitors in the sound card
3- High noise in the main power supply (SMPS)
4- For CRT tv, weak insulation of the Line Transformer
5- An external source near your TV set which is picked by your TV and amplified.

If I strum harder on my guitar a buzzing noise comes out of the amp. Also every sound I try on the amp sounds very twangy and painful to the ears. I use an overdrive pedal with it, but every setting is...


If you don't want distortion, get rid of the overdrive pedal... Twangy USUALLY comes from the GUITAR and NOT the amp... test it on a different amp to decide... Buzzing CAN be caused by "fret buzz" which is due to IMPROPER guitar setup such as neck bend and string height.
Start using ONLY clean channel on the amp and NO reverb. If you verify that the guitar sounds bad on a different amp, take it in to have it setup properly.

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.

Hi jackkikay,

A faint buzzing sound is normal - - that's the high-voltage plasma discharge simulating lightning in a thunderstorm. If the room is dark you should be able to see a faint bluish-purple glow of the metal grid on the plate(s) inside. This should somewhat louder as you increase the setting.

It should not really be so loud that is stands out in the background of normal noises (refrigerator running for example). If the buzz is loud - - like something is shorting-out internally (loud crackling sound), that would signal a different problem - - I'd need more details about what you're observing. Approximate purchase day, specific model, number of plates, general condition of the interior would all be helpful if you deem the buzz to be too loud for normal operation.

If I can be of further assistance, let me know. If this helps or solves the issue, please rate it accordingly.

Thanks in-advance for using Fixya.com,

Jon

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
