I recently replace the backlights on my Samsung UN46EH5000FXZA TV. The television was working after I replace the LED backlights, but some of the guides I looked at recommended updating the firmware on the TV to help prevent the backlights from burning out again. Ever since I updated the firmware I have not had any picture on the TV. The backlight still comes on, I can hear sound, control the tv with the remote (change volume, change source, change channel)
I downloaded the firmware from here: https://www.samsung.com/us/support/owners/product/2012-led-tv-eh40xx-eh50xx-series
Is there anyway to reset the tv to the old firmware?
