They put a new brain in mine. So far its working but the remote is messed up now and I called Samsung and they could not fix it. What is happening is I turn on the TV and it comes on with source TV and it takes a few steps and presses of the source button to get it to bring up the three choices I have to choose from to get the picture. Samsung does not know how to fix that yet.
Strange one that. Once again it may sort itself out with another software update. I suppose my set comes on strangely to a point as well. I have to push the return button to get a full picture and remove the unwanted information shown in the bottom half of the screen, or you can wait a short while for it to do it itself. Its a silly arrangement but is manageable. I am just happy the sound fault is sorted.
Just to let everyone know the latest firmware/software update, version 1361.0, does fix the popping and crackling. After doing a through test on all my external devices, blu-ray player, satellite receiver/recorder, etc no trace of this sound issues could be found on my QE55Q70RATXXU. No need to now ensure I'm first watching an SD channel before changing the source to an HDMI device. I can now happily watch an HD channel and then switch to my satellite receiver/recorder. Great news!
Although, what is annoying that despite many months posting about this issue, and owners returning their TV's, we have heard nothing from Samsung? Many hours trying to get through to Samsung and getting nowhere. Having put up with no TV for several weeks whilst they said replacing the mainboard, which solved nothing. Also, checking their support pages gives no indication of what their updates fix. Don't get me wrong having put up with this sound issue for sometime I am pleased it's now fixed - well at least for me. What I am disappointed about is why isn't Samsung contributing to these posts? Letting us know that issues like these are being looked into? Reassuring customers that their issues have been heard. Sorry, your customer service isn't good enough!
Feel better that's off my chest.
Well another funny event happened with my set I am sure that the SD up scaling is not functioning as good as it did . It was one thing that made me keep the TV despite the sound fault. I wonder if its just my old eyes! or seriously has anyone else had this problem. Better post here than try and get any sense direct.
