Samsung does not use a blink code. So what might be happening is that the the TV is self protection mode or missing the stand by voltage etc. At this point I’d try to disconnect everything from the TV, lastly the power cord. Then hold the power button down for 30 sec- 1 min. After that plug the TV back in and see if it powers on. If it does not, remove the back from your TV and take a close look at all of your boards. Check for obviously damaged components, scorch marks etc. Post some good pictures of your board and the interconnect wiring with your question. That way we can see what you see. USe this guide Adding images to an existing question for that. You will need at least a multimeter for any further testing. Let us know what you find.
