LG 47LG70 Video Board P800 Soldering

[Taterbug]

I have an LG 47LG70 that has no video or audio. Backlight works fine. I was examining the video board and noticed on connector P800 on the board that the pins are soldered on the bottom of the board but a lot of them are not on top. Is this normal? Should they be soldered on both sides of all the pins. I am attaching a photo so you can see that I am talking about. Looks like on the bottom of the board it is 12v, 16v Grn, and 5v pins. Board has number EAX55177902 (0) stamped on it.

No not needed ,the holes are bonded through and require only to be soldered one side

Check the DCV of the SMD fuse on the T-CON board to make sure it show Voltage (either 5V or 12V depends on the LCD panel) at both end of the fuse with ref to the chassis GND.

checked the voltage on the fuse on t-con board and it is 12 volts. Suspect that the video board is bad but cant find a replacement anywhere. Has anyone found any repairs for this video board?
