Vizio 42 in. LCD TV Logo
Anonymous Posted on Jun 15, 2011

My 6-month old tv is making intermittent 'buzzing" sounds. It was a Christmas gift and I don't have any paperwork on it but it did come from Costco. What should I do? Thanks so much.

Humming usually begins when the backlight setting is low. For some sets setting the backlight anywhere from 95 to 100 works. Most wok at 100. So turning it up should get rid of the problem. You can follow the 5 steps below to change the backlight setting.

1. Turn the TV on.
2. Press the Menu button on the remote, located right below the channel changing button.
3. Press the down direction button, located at the middle of the remote. Press that button until the backlight is highlighted.
4. Press the right direction button until the backlight is at 100.
5. Press the OK button and then the Exit button until you get back to your picture.

Meet Kids? Requirement for Apple Products or not in This Coming...

It is reported thatkid this Christmas would not be pleased with toys as they are exposed to high-techvideo games and cell phones. In the contrast, they also want to have a closecontact with apple's products such as ipod touch, iphone, ipad or otheradvanced gadgets . According to Duracell Toy Report, out ofthe surveyed 2,138 kids, 39 per cent want an Apple product. Seventy per cent5-8 year olds, 50 per cent to 9-12 year olds, and 16 per cent of 13-16 yearolds wanted an Apple product this Christmas. The Apple <span>iPhone4, the Apple iPod Touch and the Apple iPad tablet computer were the three mostdesired Christmas gifts among children, with age group ranging from 5 to 16years. What a great shock for parents for they are too young to play these dearand advanced products.</span> Owing to this trend among those kids,some school made a survey that how much do they learn about ipod , iphone ,ipad."I know ipod well. <a>The iPod is a combination portabledigital media player and hard drive from Apple Computer. The original versionwas about the of a deck of playing cards, with a monochrome screen and a 5gigabyte capacity. iPods can be now be purchased with up to 60 GB of hard drivecapacity and color screens capable of playing television shows, videos ormovies uploaded from a PC. </a> <span>"AniPod can be connected to a computer with either a FireWire or USB port, withmany of the latest versions depending upon USB 2.0. iPods have a reputation forbeing user-friendly." A 10 years old boy said to his teacher. "How can youlearn so much about this?" Can you tell us some other information about ipodsuch as how to </span><a href="http://www.ipod-computer.net/guide/transfer-music-from-ipod-to-computer.html"><span>transfer music from ipod to computer</span></a><span>?"His teacher said to the little boy in a amazing manner. "Yes of course , exceptfor this, while the iPod was originally platform dependent, after July 2004iPods (and Apple's iTunes software, included with each unit) worked on eitherWindows or Mac. iTunes makes it possible to load an entire CD onto an iPod inas little as ten seconds, organize thousands of songs into favorite playlists,purchase songs, albums, videos and movies from the online store and subscribeto podcasts. The iPod supports most audio file formats including MP3, WAV, andAAC. As of October 2006, the iPod was the world's most popular portable digitalmedia player, with more than 60 million units sold worldwide. </span>Ofcourse we can transfer ipod's contents to computer through a <span><a href="http://www.ipod-computer.net/"> ipod to computer transfer </a>softwarein case of losing ipod."</span> According to the dialogue between the teacher and hisstudent, I think we won't be surprised at the fact that fourteen per cent of the respondents saidthat they wanted an iPhone, while iPod Touch <span>and iPadwere voted by 13 per cent and 12 per cent, respectively. In the list of mostwanted gifts, Kinect for Xbox grabbed fourth position, while Kung Zhu Hamsters,Flip Video Camera, Toy Story 3 Jet Pack Buzz Lightyearsecured fifth, sixth and seventh spots, respectively. </span> "Althoughsome kids have a better understanding of these advanced apple products, it is stilla big problem that can we meet their needs to buy their ipod or iphone in thiscoming chirstmas." Most parents exclaimed.

Light flashes when I try to turn on tv but it turns itself back off

The voltage regulator or capacitor on the circut board is blown. You will have to call the repair people. There are no user friendly parts you can replace. Maybe if you can find the receipt their customer service may reconsider.
