Wrong voltage on Sharp Aquos? Odd fix for buzzing sound..

[Bear28]

Hi,

I had a loud buzzing from my tv last week and called Aquos Advantage. The super nice and friendly lady booked an appt for today to have someone come out and look at it.

The guy showed up and was here for maybe 5min. All he did was look at my menu settings, and adjust the Backlight to 11 out of 16. He said that this is why the buzzing was happened, and it was due to the voltage being too low. Increasing this increases the voltage of the back lamps.

I told him but that would change my picture quality but he didn't feel like listening. After he left I set my backlight to 3 out of 16.

Anyone else know if this "fix" makes any sense at all??

Thanks
