@Geo tracks
how can u confirm for sure that the sonys use SPVA.
That's what I said in the post. I cannot confirm, since I have not taken a visual (neither on the packaging box nor behind the LCD panel). But since sales guys from both, Ezone & SONY Center, confirmed the same thing (SONY using SPVA panels in both 40S550 & 40V550), had to take it at face value.
If you do get a chance and check out the panels for these 2 SONY LCDs with the 10x magnifying glass (as you said in your earlier posts), please do let us know your findings and confirm.
