Hello . I am in possession of a TV le40a656a1f .
Today I was doing the update via usb and came off the current.
Since that time the TV screen remains black .
I try to make the flash via " samsung set-top box upgrade" but nothing.
What can I do to make it work ?
thanks

try hot plug method,it worked for me,the tv was stuck on blinking stand by led,because of upgrade failure,so i followed this:
"Use the hotplug method, with TV off put the USB stick (with FW file saved to folder named MT8226) then press the source button at bottom right side of the set, then at same time hold the power on button on the remote. Message should come on saying upgrading"
Only thing is,that you dont see anything,because of black screen,but its in progress,i just waited untill tv switched off itself,then i started it and here it is
