Has anyone experienced this problem where the TV would turn on and off by itself. No display and no audio. Just the melody you would hear during power ON. I tried resetting the tv and unplugged and replugged the A/C and has no luck. Samsung tech recommended a firmware upgrade, but which is impossible since you could not access the menu in the first place.

I returned it, and got another brand. Was afraid of getting the same in production run. This had happened in both the 46" and 52".


Anyone who has experience and managed to repair or avoid it?

You would upgrade the firmware from a thumbdrive. There is no need to access the service menu because if you do on your own, the warranty is voided.


But since you have already gone with another brand, it really doesn't matter anymore now.

I could still exchange to another LN46A750 but I still have worries what if this problem happens again, it's a lot of hassle.
