Anyway ano po ba plasma nila sir?
Panasonic Viera 42PA60M, 42" EDTV 9th gen.
It's the last of its kind. Panasonic does not make EDTV 480p consumer plasmas anymore.
panasonic plasma has anti image retention - scrolling bar option, is this the same as white wash option?
No. Panasonic's White Bar Scroll is for image retention (residual charge in the plasma cell). White Wash is for burn-in (uneven phosphor burn).
A White Bar Scroll functions as a screen conditioner, similar to a CRT's automatic degausser.
Creath.net (not a Panasonic site) says:
"White Bar Scroll" sends a wide, vertical, white bar scrolling across the screen. This area of even brightness theoretically wipes away temporary burn in. It appears to work. If the panel is truly burned in from long periods of misuse, the white bar scroll won't help.
