I have been experiencing some issues lately with volume control as well as some other button functionality. First attempt for resolution was the community and I had seen multiple remedies but all seemed to only work for a short time: power cycle, disable auto smart features, reduce memory usage, reconnect remote control to tv, etc. After many infuriating and interrupted tv usage sessions I gave up and tried the self diagnose(btw no issues with volume control during test). But it did recommend to call Samsung's call center which I looked up the number and called. Seems that there is a know glitch with the 1290 system version but they were unsure when the new update(version 1299) would be available for online download. Has anybody else been given this resolution and installed and seen positive changes? Also as far as installing updates via USB drive, is there anything I should know going into the process.
