Both the LED power board and the LED strips were dead. New LED's and Card ~$100. SO the salvage unit was repaired with cool LED strips from Amazon - Total cost (not including what I had on-hand) ~$16
Not ideal for a regular TV, but of little issue fo this salvaged TV. There are likely internal sources for power, but not knowing the current capabilities, an external power supply was used.
