I wish I could anything usable about the bars, other than my last plasma (rip) never shown any issues related to black bars in it's 6 years of life
Slight off-topic - why pay extra for VT30, then GT30 is exactly same panel - the difference is at least $600 or that matter ST30 lacks the THX cert and advanced controls, but in the end of the day is essentially same panel
But 2012 VT50 is actually a brand new panel, which lower models don't get
My budget choice was 55ST30, but if I'd be looking for top dog, I'd get xxVT50
