My LN52A750 went into servicing (Future Shop PSP) and after the PQ looked a bit different. Going into SW Update and pressing info gave me something interesting. I thought the latest firmware update for the LN52A750 was only at 1012 but mines ended up being 1014.
I don't know if this help but I get this for info on SW update "Module: T-RBYAUSC-1014.0 Date: 2009-05-22, MICOM: T_RBYAUSS-1003"
I would like to know which model this new display came from if possible.
