Identifying different panels on the 40" PFL55 series

[Blackice012]

Hello, I am very much interested in buying a Phillips 40PFL5507H television. After the summer, Philips changed the screen panels for the 40PFL5507. Due to high demand newly manufactured TV's did not have the original Sharp UV2A panel anymore; this was replaced by the Samsung PVA panel. I do want the original Sharp UV2A panel and not the Samsung PVA panel.

I would like to know how i can identify which panel i am dealing with in the shop, or at home after i bought it online - without opening up the TV as this would void any warranty. I want the UV2A panel because the new PVA panel is not worth the price of this television.

Now i did some research and found out that the code for the UV2A panel is LK400D3LC, for which the identifying number seems to be 400, and the code for the PVA panel is LTA400HV for which the number seems to be 396. Often the sticker that has this code on it will have been removed and I do not know if these numbers are correct. Can anyone confirm this?

Is there any way to identify which panel i have without opening the TV, when i can't compare the two different versions? Production dates, codes, registration numbers (maybe you can tell me up until which production week the UV2A panels were used, since the production week should be in the serial number)..?

Or is it possible to look at the pixels with a magnifying glass and see which panel i am dealing with?
