Probably the best way to find out the panel is to get into the TV's service menu.
[ Note: Entering the service menu will reset the TV settings to factory default !! ]
To enter the service menu:
(TV in Standby Mode)
Mute, 1, 8, 2, Power (in rapid succession).
(Non-US versions, Press info-menu-mute-power)
Look under "Option" or "Type".
Search for your model's "inch number", and look at the letter immediately following the "inch number"
R:AUO (au optronics)
So a UN40EH5000 with a samsung panel, would like this: 40A6AF0D
Exit with power off on remote.
