Yesterday i upgraded my Samsung LCD TV LA40B6450T1M's firmware. At first im quite nervous. Oh come on, i dont want our very own 40 inches tv to become a brick. Downloaded firmware at www.samsung.com.sg/support page, unzipped software at my thumbdrive, load the firmware using the update utility of the TV.. and that's it. Proud owner of one of the latest LCD tv in the world with updated firmware.
