Hey all...anyone know anything about LCD TVs? My 4 year old Vizio LCD just started to have a loud annoying buzzing sound. It seems to mostly occur when it is turned on for the first time. I think it eventually lowers in volume and when we turn off the TV and then turn it on again later, it doesn't seem to be there.
I tried to make a recording of it--you can sort of hear it but it didn't turn out as good as I hoped. I notice that as the TV "warms" up and goes through some flashed on the screen, there are various buzzes that occur and then it goes into the louder one for a bit. Just wondering if anyone out there has experienced anything like this or has an idea of what could be causing it. Backlight? It shouldn't be speakers since they are turned off and we run it through a home theater set. Just wondering if it is normal and I just noticed it or if it could be the start of a bigger problem.
