Some help please

So I have a FoxPro game call for hunting and it stop working. After doing some inspection I noticed that the board does receive power but it doesn't do any else. Hooking a 9v battery to the connector instead of the battery pack I get a flash of the green and the speaker makes noises but nothing until I jiggle the connector and then I get noise again. I tested the board and it's getting power but I'm getting no output. I was wondering what I might be causeing this issue. Thanks in advance.

P.S

I attached photos of the board so you have a visual with I'm working with

Why are the pink and the brown wires, on the right side, disconnected? Was the solder joint broken or? 

Thing is you can guess but i am not sure how to find the chip responsible for video output without schematics.

Did you try to google the board to check out what is available online?

The pink and brown where for the antenna connection and I didn't find anything looking up the board, but I see multiple markings on the board with revisions and I'll see if I can find anything. Thanks for the response.

Please use reply button or tag people when you are responding with @Kadzo so i can see that you have responded. 

If you are getting power but no output signal usually that means there is a problem with the display chip itself, of the connection from the board to the display. 

Are there any visual signs of dead parts or corrosion on some parts?

 

Edit: did you check the screen itself? Eliminate the connection from the board to the screen, do a continuity test on the wires check all the solder points, then the screen, after that there is not much you can do besides checking the chips.

Im willing to bet these two wires got pulled from these two VIAs with solder in them

Personally I'd say this makes more sense. Although I have no idea what these wires or this board are for and how they work. (could be the other way round of course)

could be either, agreed. Really just looking for what's off and guessing.

With these off brand boards that is all we can do, but according to OP those two wires are from the antenna.

^this it clearly shows that something was soldered on those 2 solder pads and those wires are clearly part of that bundle go for it what could happen other than experiencing the joy of magic smoke!
