I'm having a small issue with my passenger side rear DVD monitor. It's not powering on. Driver side works great. I've swapped monitors and have confirmed that both monitors are indeed working fine. I've checked and replaced the fuses in the rear of the cabin, even though they were fine. It seems that I'm dealing with a power/cabling issue or a possible "board" issue in the headrest.

Are there any sort of write ups or schematics with the DVD system? I have the center console dvd system, one 10+ pin connector from board to back of monitor.

2007 XC90 V8 Sport.
