OK, do you have multimeter and can check volts on circuit board to troubleshoot the issue?
Yes, typing an answer for you, give me 2 minutes please.
I understand, if power LED/ light on TV doesn't lit when plug TV power cord that means TV isn't booting up form some reason. Since power board has already been replaced that means main board is defective, this board has main processor chip which isn't booting up to give picture, control menu options etc.
