Thanks for the response on U405 on back of main board. I changed this to fix the issue as well. Even though the post is old it worked great.
More info on issue was TV was completely dead & wouldn't power on at all (even the standby LED wouldn't light up at all). I verified power supply board was good by measuring the power board & main board connection cable & was getting the right Volts DC needed on the cable pins into the main board.
I used part # MAX810LEUR+T as a compatible part (ordered from Digikey. It's a very small surface mount 3 pin component & was a bit of a pain to solder on.
