Since buying my pin, the game would sometimes make a loud pop when turning on. And a few times, while playing the game, i would notice the backglass LED and LED strip under the cabinet cut in and out while the speakers were making some loud popping noises. I noticed it mostly in the under cabinet LED strip, so i disconnected it. I then kept noticing it happening behind the backglass, so i removed the LED panel and re-installed the original bulb. I no longer see any flickering, but the noise when i turned on the machine was still there. Stayed like that for a few days, but just now when booting up the machine, i no longer hear the loud popping noise, but i also no longer hear any audio. I'm guessing that whatever was on it's way out, finally went, but i have no idea where to look. I've checked the boards for any visual signs, but all seems normal. Anyone have an idea of what went?

Grrrr, it's something that's loose, no idea what. I just wiggled and pressed on everything and now the sound works again. I wonder if i should re flow solder on all the connections.
