My Sanyo 50749 plasma tv was working just fine but out of nowhere it wouldnt turn on. First when i pressed the power button it would show the power light for about 3 seconds then power off. It did this for about 3 tries then stopped. Anyway i bought a new power board and it is the exact model of the old one. I replaced it and tried it but now it wont even show the power light. Plz help any suggestions would be helpful.

@mpanther_42 since you have no signs of life with the replacement power board, put your old one back in and see what you get with that. Next thing you want to do is to take plenty of pictures of your boards and post those with your question. For that use this guide. It will allow us to see what you see.
After that proceed by following the troubleshooting flowchart and let us knw what you find.
