This sounds a lot like something I noted several months ago, so to recap (and elaborate):
My PN60E8000 will only lock into an endless loop of start/restart if it's connected to the internet via wifi OR
In my case at least it can't be just the wifi card since LAN does the same thing, but faster! It seems to be logging in and getting some sort of reboot signal, thus LAN is a faster cycle than wifi.
Samsung replaced the motherboard months ago but that did not fix the issue. It seemed to be a fix when the tech was here because the TV can be connected after boot - the bug only seems to affect my TV if it has Internet access when the TV starts up! When the tech was here we didn't actually restart the TV again after the initial set-up & log in worked smoothly.
But here's the real kink - It works fine if my main computer is is removed from the network!
I think this indicates that the TV is open to some sort of exploit coming from my PC. Hopefully someone with more networking knowledge will have a better idea.
My set-up is a D-link router wired (LAN) to a Lenovo notebook (Windows 8), Router is also wired (LAN) to Oppo Bdp-93. Router wifi connections to a Toshiba notebook (Vista), Android phone, and the E8000 (Ideally!). If I remove the Lenovo notebook the TV is happy. So it seems that something specifically on this computer is being read as a constant reboot command by the TV. I can't find any apparent malware on the notebook. I've removed Anyshare software and just use Oshare (a very simple DNLA which is great with my Oppo).
Samsung was willing to keep replacing parts but it seems that the problem is mostly within my notebook & the Samsung's problem is that it is open to this weird exploit. And if so I wonder what else it's open to? I've been out of commission for a few months & haven't had the time to book service calls so I've just been using it as a 'dumb' TV (and what a waste that is!) I'm now well out of the Samsung warranty -- though they might still be willing to finish this ongoing repair. I do have a couple more years on my Future Shop warranty - but if the problem is really on the PC side it seems pointless to keep replacing TV components.
If anyone here has any idea of what sort of signal the Lenovo could be sending to the TV please let me know!
