Hi I have a Samsung ue40d5520 TV. I was messing with the Service menu by pressing INFO - Menu - MUTE - Power. Then if was saying Wait. I can only assume it was doing something to the software installed on the TV. This Wait message was staying for too long for my liking and I decided to unplug the TV. When I plugged it back in the TV would not power up at all. There isn’t even the stanby light. It is bricked. There is electicity going to it as removed the back cover and unplugged the main motherboard and the screen would turn into white. I assume the firmware data on the main board is currupt. How do I fix the TV. How do I install the firmware again.
The Firwmare is here. You need to follow its instructions on a PC on how to copy it to a USB.
