3 Red Flashes. Screen won't come on.

I have a Sony KDL-55W802A tv. Walked into the room the other day and the tv wouldn't turn on and the red light would repeatedly flash 3 times. I looked up the code and it said it was either a bad main logic board or the power board. I tested and replaced the power board to no avail. Can anyone please give me insight into this issue? I'm stumped!
