chrisnewton - that is correct, leaving the TV in DTV mode before turning off; switching to a HDMI input that is not on GAME mode; or turning the TV on using a channel number on the remote (thus launching the DTV) are all ways around the black screen issue.
Samsung are aware of this issue and will hopefully fix it with the next firmware update.
I have gone through a lot of trouble shooting with Samsung (USA) & they have been able to reproduce the issue on their test unit which means, a fix should hopefully be coming with the next firmware update. I guess a bit of patience is now required.
I have been having this exact same issue. I have gone through 4 nu7100s and I just got the Q6FN and it has the exact same issue. I have contacted Samsung each time and each time they tell me there are "no reported issues" similar to my issue, that they have no plan on fixing it, and that it is a hardware issue, which it's not becuase I can run everything just fine but the menu will not appear. I'm not sure if i should return my TV and call it quits on Samsung for good or try again... Any comments or help?
It sounds like you are being served up some Samsung customer service garbage. The issue happens across all these lines (NU7, NU8 & QG series) and they know about it. The problem is, one guy I have dealt with knows about it, everyone else at Samsung seems oblivious. It’s a bit of a farce to be honest.
I’m going to wait for a fix (I will give them until my warranty is up) as the issue is minimal and I have adjusted to turning on the TV first to DTV then switching to the HDMI input. If you aren’t comfortable, ask for a refund and get yourself a different brand.
The different brands just don't seem to hold up to Samsung quality which is a shame becasue they are ruining their repuation for me with this issue and how they are handling it. There is one left within 250 miles and I think I'm going to take a shot and make an exhange. I'm terrified that it may have other issues or even be physically broken but I guess I'm going to roll the die...
