If I had to be instructed on which buttons to push to resolve this, I would say Beams system is just like mine. X3, v1.6b, xbmc dash (pre-mod). I didn't have enough time to memorize any steps, but if you could tell me which ones to press from boot-up & X3 Config Live to the point of changing the video back to ntsc-u or PAL this should do it as sound and lights are correctly booting.
