Televisions have changed since the day when only an authorized technician could update the operating system the TV used. Updating the firmware on a Samsung Plasma TV can be done by the owner, but problems can develop if the Samsung is accidentally turned off or the electrical power fails while the update is being made. Resetting the firmware becomes necessary as otherwise the Samsung Plasma TV will no longer turn on or off. The owner can reset the firmware using the same firmware update that caused the problem. It will only take a couple of minutes to get the Samsung Plasma TV working properly again.
Remove the USB flash drive firmware update from out of the USB port on the Samsung Plasma TV.
