Seiki SE50FY28 No Video Power Control Board mixed up

[Gadjet]

Ok this tv came in with no power, no standby light. I had a replacment power supply and that did nothing because the power contol board and the rf board both run to a connection on the mainboard so I replaced the mainboard. Now I get the red standby light but when I click the power button I get nothing. So I decide to hit all of the buttons and when i click the vol.up button the standby light turns blue and the tv powers on, but no picture, and I don't even see a backlight.

Can you post pictures of the labels on both main boards
Can the cable from the on/off be connected the wrong way?

Pics left to right the first one is the old main board 2nd one is the new one. 3rd pic is the control board / rf connector with the white dot that I'm guessing should be pin #1 along with the arrow on the board. Doesn't seem that it can be plugged in the wrong way

Well may be good news and terrible news.
Sadly good news is the cable can only be plugged in one way.
Terrible news is I think your replacement board is for a 47 inch Seiki.

So you think the control board pin set might be different on the other model? didn't match the M/O # and the C/N #

The main board eeprom probably has a different dataset and drivers for the size of screen.
SJ are pretty good at saying which boards is for which set they do have both and they only mention the one set for each board.
If you got your board from them they will probably let you exchange it.

I finally got a chance to change out this board with one with the exact same board information as the original just to have it do the same thing as the wrong board. So now I'm guessing that I need to change the firmware for the board but can't find it. Anybody have a clue or know how I can get it?
