This is how we can check the panels -
1. Without opening the BOX -
We can find the version number and the type of panel corresponding to it:
SS 01, 02, 03, 04 or SQ 01, 02, 03, 04 -> S-PVA from Samsung
CN 01, 02 -> S-MVA from CMO
BN 01, 02, 05, 06, 07 -> S-MVA from CMO
АА 01, 02, 03, 04 or АC 02, 04 -> A-MVA from AUO
AC 02 -> New panel A-MVA3 from AUO
=====================
2. After opening the BOX -
Firstly, you enter the SERVICE menu.
Switch off the TV; let the main power ON. Now press these buttons in the mentioned sequence - Info > Menu > Mute > Power. Now look for the "Type" line -
It would be something like this - 32A1AF0L
32 — screen size in inches
A — panel manufacturer (A = Samsung; D = CMO; L = AUO; I = CPT)
1 — frequency (6 = 50/60 Hz; 1 = 100/120 Hz; 2 = 200/240 Hz)
U — panel (A = Anti Glare; T = TN; U = Ultra Clear)
F — resolution (F = Full HD; H = HD; U = UD)
0 — 1st, 2nd panel and so on (1st = 0; 2nd = 1 ...)
C — backlight unit (C = CCFL; L = LED; E = Edge LED)
Now, finally about the Panel Quality - Spva>Amva>Smva
-------
Now, the worse part is, the box package Version checking is not a 100% sure method. And the second method, (although 100% sure thing) is not possible without opening the box. And that dealers don't allow!
Between, just because of this panel lottery system by Samsung; I am getting inclined to SONY KLV-32EX330 - KLV-32EX330 : EX330 Series : BRAVIA
