Masarap talaga sir ang free , hehehehe... Thank you po sa links. Sabi ng tech kanina now lang daw siya naka experience ng plasma na 64inches na may horizontal banding on white screen tinuro ko rin yun pink blush sa screen , kumuha sila ng picture for documentation . nagawa sila ng report pinoprocess na request ko is replace the unit . I'll keep you updated para alam nyo kung paano ang magiging reaction ni samsung dito sa case ko.
First time ko mag 64 inches pero marami problema like buzzing sound( pwede ko na nga pagtyagaan kung okay yung screen uniformity) , horizontal banding, pinkish white na parang blush tsaka putol ang letters sa bbc kapag analog cable tv.
Horizontal band and pink discoloration, opinion ko, sa filter yan. Parang tint ng car window yan, mahirap talang i-perfect. Walang remedyo yan.
Also, we have to be careful when cleaning the front panel, hindi basta glass yan, may plastic filter na parang sticker.
Malala nga yung ibang series ng Panny plasma, green and pink pa:
Look for the green blob on the center and pink tint on the sides:
Panny VT30 (2011)
Panny VT50 (2012)

May guhit din sa screen yung Panny, pero vertical band naman...
Yung Sammy plasma 51E550 ko, meron ding slight green and pink, pero slight lang:

Buzzing sound, hindi ko pa na-experience, pero sa US forums, sangkatutak ang ganyang issue. Normal lang siguro, usually sa 64 inchers. Depende rin sa room acoustics and hearing acuity ng user.
Putol ang letters sa BBC? Don't use cable TV as basis. Use test patterns.
Try AVSHD709 mp4 file (already linked above:

--- Basic Settings > 5-Sharpness & Overscan.mp4
Yan ang tamang test.
