No power, no standby light, no TV. Replaced both the power board and main board. Didn’t fix the problem. Tested the power cord, it works. Checked fuse on both old and new power board, both are good. What the heck….any idea’s

Jeff Johnson  ..No power, no standby light …. this only happens when the ac/dc adapter is gone or the power supply is gone. you replaced the power supply. what voltage are you getting from your ac/dc adapter? im assuming youve checked your wall outlet?
