Hello there. I just bought a SONY KDLEX520 32inch TV yesterday. when i turned the tv on it was perfect, everything was great. Later on that night when i turned it off i just sat on my bed admiring it, but...


There's probably a bad capacitor in the power supply causing a transformer to hum. This will be a 125-195 dollar fix through a repair shop if you act like you know what you're talking about.

37" Philips LCD no sound.


Maybe the antenna that you are using is not picking up sound from the channels. It could also be the cable. If it makes a humming noise, it means that the speakers are getting electric current and that they SHOULD be okay. It also could be your tuner. Maybe check it all out at some tech place like best buy. Those guys can help

My lcd tv makes a humming noise


My 37 inch vizio did the same thing. go to your menu screen on the tv and go sound. My tv has an option to turn speakers on/off. Once I turned my speakers off and the back on again everything worked great. hope I helped! if I did please let me know! youtube.com/xniax1

My lcd tv makes a humming noise


Try removing all cables going to the TV except the power cord. Power on the TV and press mute. If you have any unwanted noise, then you have a defective TV and since it is new, you should get an exchange. If there is no noise with the A/V cables removed, then you might have hooked the source (cable box/DVD Player) into the wrong inputs of the TV.

Poor sound quality


Hi, I sent an email regarding the issue to OnCorpus (the company who makes ProScan)

This is what I got back:

---------------------------
Thomas,
Follow these steps to correct humming issue:
1. Turn tv on
2. Input mode should be tv
3. Turn volume to zero
4. With remote enter 9 8 7 6
5. A menu will appear on left side
6. Arrow down to backlight and with right arrow key move number from 81 to 83, press menu button twice,
7. Turn up volume and listen if hum is gone.

I can't confirm if this works at this moment since I don't have access to my TV.

Referral from Ekse. DLP Samsung spinning noise


the most likely cause would be either the color wheel or the cooling fan. If you listen at the rear cover can you dtermine where the noise is loudest? does the noise instantly go away when you turn the power off after its been on awhile? If so its the color wheel, If not its the cooling fan.

LG LC55 humming/buzzing


Have you tried adjusting the contrast? , have a similar problem with a 42'' lcd and it appears to be related to the contrast setting .If is set my contrast below 90% the buzzing sound stops.
This buzzing sound seems to be a common problem with LG TV's
