Thanks for your message. But just so you know, if you want Samsung support, I support US products and customers. So if you want Samsung help, here's the Samsung Netherlands portal for support on that product: http://www.samsung.com/nl/support/model/PS50C7000YWXXC
But we got a nice little community here that includes people from everywhere in the world, and they might have a few other suggestions to help you out.
Hope this helps you!
I have a samsung ps50c7700 3D tv and while upgrading the firmware my usb disk crashed. Now my tv restarting the whole time. After i unplug the electric and plug it on again it start to restart again. So i think the firmware has been damaged cause of the usb disk. I tried to solve the problem to put the firmware at a new usb disk and plug it in my tv while its unplugged from the electric. Then i plugin the electric again and push the power button at my tv for 4 or 5 seconds. But i do not get a window for a reset of my firmware. I tried both usb ports but none of them is helping. Maybe this is not working at this model cause of the tip buttons. There are not realy physical button at the front of the tv.
Does anybody got an idea how to solve this problem?
I hope someone can help me cause i have know clue anymore how to solve this problem. My appologize for my english. I am dutch.
