Zoyd, im wondering if you could try something for me as I have no experience in such matters.
I have a PS51D450, and the latest EU firmware is t-msv4deuc 1006.1
However, on samsung india website, their version of the PS51D450 has a firmware dated january 12, 2012. Looking at the specs i have no reason to believe its substantially different
Would it be possible for you to take a look at its newer firmwarfe and see if there is a logic board update in there for the D450 ? at least if you extract it I can try and see if the TV would accept it from the 7-3-7 menu
here is a link to the firmwarehttp://org.downloadcenter.samsung.co...7/Firmware.exe
Im interested in what might be in the t-msv4daac 1004.1 package bundled in the download
many thanks in advance if you can be bothered to take a look!
