Six day old Vizio making buzzing sound from the back of TV, saw some other reviews but TV was older. Buzzing can be dround out by turning up volume but when you want to keep it low, you can hear it. Make have to take her back. Any Ideas!!

It just happened to me on 4/7/10. My vizio p50hdm made a popped noise & did not turn on. I purchased the tv at costco on June 2005 w/amex card. I pulled my amex statements from 2005 then called costco with my member # and they found the transaction. If you purchased the tv before 4/2007 the item is grandfathered with the 100% customer garrantee. After 4/2007 the return policy changed to 90 day money back return 2 year warranty and you get an additional year if you purchase w/amex card for a total of 3 years. Be very nice to the Costco people even if they give you an attitude on the return of tv. I got a credit for $2200. I just purchased a samsung led tv 46 series6 back lit & internet. Amazing Technology. & I Love Costco
Vizio makes an ok LCD, but if you notice they no longer make plasma. they stopped last year. Anyways. the buzzing sound is semi serious, it sounds as though you have a capacitor leaking. It is best to get it fixed before it goes out all the way, with it buzzing it will be easier to identify. Best of luck
I had the same issue happen to my vizio lcd just this weekend. Everyone is telling me is a bulb or backlight or something. It would explain the loud pop and no picture, but I'm not getting sound either so I'm not sure what exactly happened. Only after about 2 years too. I'm trying to find parts to just fix it myself.
