I don't have the older firmware updates for the LCD models, unfortunately. I could request them, but those requests do not always result in getting the firmware.
I was wondering if anyone knew
1) If the 1012.3 currently on the site is 1012 or 1013?
2) If there is a location where you can download older firmware?
1013 has an issue with A/V being out of sync when using the the digital out from the TV and watching the OTA tuner. What's worse is that it is the audio lagging behind the video so I cannot adjust for it with my AVR.
I fixed it by rolling back to 1012, but I am afraid the next update will not have this issue corrected and then I will lose 1012 since the TV only retains the latest 2 firmwares.
