Well, I am noticing that our HOTD game sometimes has sound only coming from the LH speaker. I've determined the culprit to be this PCB, I can wiggle it and the RH audio will come back for awhile. I have tried replacing connectors, touching up any solder joint that looks even remotely questionable and I dont see any cracks or broken traces, but the problem is still present. I'm ready to give up and buy another one. Anyone? The PCB is tagged SJ25-0247-02 and also has a sticker tagged 838-11650-24.

I cant find this anywhere, can anyone help?

going out on a limb here, i see that huge heat sink, 2 transistors? maybe one for each channel? could try swapping them to see if the issue stays with the transistor, or if it stays in the same channel. if it follows the transistor, you know that is the problem.
 
The heat sink is a sweet spot, meaning I can apply pressure to it and both speakers will come on, but as soon as I let go, the RH speaker goes out again. I may try reflowing some solder joints there, but heres a "still loking" bump in the meantime.
 
I have a working one. It's behind quite a few cabs. If you can't get your's sorted out let me know and we'll work something out.
