For those running the slides still or can remember, when the bright slides (white/red) came up did the buzz become pretty audible? I'm just curious if the buzz I have is awkward or not. Wen the white slide comes up it buzzes pretty loud but also could be room dimensions and placement of the TV since it's near the wall. I remember my KURO buzzing loud in my room but once moved to a bigger
Environment like the living room
It was a non issue
I didn't find moving either of the two 50ST60s or one S60 I had in my house away from the wall helped any. Taking the backs off didn't help any. Tightening screws internal and external didn't help any, and the internal ones all had the washers that were absent from an earlier series. I couldn't feel any components vibrating or locate any with cracked housing.
The bright slides are a predictor of what the TV will sound like when displaying high APL scenes. If you hear buzzing during the bright slides, you will hear it when high APL scenes coincide with similar levels of background quietness. For me, that's been rare enough that buzzing has been a minor issue when actually watching TV. I notice the rainbow effect and line bleed far more regularly than I notice buzzing. For all the plasma issues, for me it's still better than the poor black levels and uniformity of LCD and the blooming that affects the local dimming feature designed to mitigate those issues.
