Thanks to this thread:

I found the manual and the picture that shows the panel 12v 34pin detection failure.

I do not know how to go about checking this.

I bought a replacement powerboard online and it still did not fix the problem, so I am wondering if its the mainboard, but I do not want to waste my money if this wont fix it either.

I tried getting into a service mode, but can not.

Freakaft8 has some useful info in this post about the blinking issue but I am not sure how to decipher it

This post talks about forcing the tv to start.

Any help would be appreciated. I am a hobbyist an not a repair person.

if you can, post some good clear pics. of each board and one of how they are all connected, be careful when working with power supply, HIGH VOLTAGE on primary side can be deadly.
