I ordered a new Board/BU Unit for my TV since it was almost confirmed that's what was causing the issue Now after replacing the board when I switch on the TV it goes into standby mode the standby light blinks 12 times and keeps repeating 12 times with few seconds gap, I tried unplugging and reconnecting the board few time to make sure that its installed correctly - when I put back my old board the old issue comes back so looks like I am doing it correct. Any thoughts

thanks
