A new Toshiba 32av502u flat panel TV is now making a constant humming sound -- it gets drowned out when the volume is turned up but at low volumes you can definitely hear it. Can I do anything to easily fix it? Does the set need to be returned or repaired?

Re: humming sound from new TV
Thank you for the info. I would suggest to take it back from where you bought it from if the store will allow a 90 days return and replace it for a new one, or you can contact Toshiba to get it fixed under warranty. There should not be any humming noise on the speakers.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

OK if you are getting a popping sound from your speakers then it's provably your signal board. IF you are getting a popping sound from one of your parts like the power supply then its provably that part that is bad. You can get parts at www.interliquidparts.com
First off, take the batteries out of your remote to see if it is a problem with your remote, if it is I would buy a new universal remote and try that. If none of this works then the problem is with your tv itself. Either the volume button on the tv is broken and works on its own, or the tv is having programming errors and you will need to have it fixed.
Bulb? LCD tvs do not have a bulb it only has a panel with a backlight sealed into it. Is that what you replaced? The problem though is related to the backlight not coming on. This is due to a faulty backlight inverter board(replacement costs about 50$) which should be replaced to solve this problem.
i have had the same problem with tv.what i did is taped the volume up button on the tv a little hard and it has seemed to fix it for now.as of 1-12-2011 if it does not stay then i will disconnect the wires going to the volume switch.the switch is defective not the remote.
As far as i remember Samsung makes all the screens Toshiba uses. I would try to contact Toshiba for a replacement screen, from what i've heard the price of the screen is comparable with the price of a new TV
Ur power supply board.Transformers have have high voltage gap.This problems must take the tv aparts put some glue arond the transformers,sometime solved this problems,or must replaced all the trnsformers make the humming noise.Brand new tv take it back,where u bought it get a replacement or call the Manufacture help to fix the problems or replaced the part that cause the problem.
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.
I think I had the same problem. This is how I fixed it.
I have my vizio 42 hooked up to a Harmon Kardon surround sound, and the digital cable box. Essentially, I can adjust the volume 3 ways - through the tv, cable box or av receiver. The humming sound happens when you have the volume maxed out on the av receiver and not the cable box.
For example, the sound level on my Harmon Kardon goes from -10 (lowest) to 10 (loudest), with 0 being the middle ground. The buzzing was happening when the Harmon Kardon was set to 10, and I was using the cable box volume to adjust the sound. To fix it, I turned down the volume on my receiver to 0, which may be about 50% max volume of the receiver. Then, I switched devices and used the volume on my cable box. This got rid of the static I was getting. Hope that helps.
