Both headrest monitors have lost power together; no response to PWR buttons or remotes. What fuse (and location) powers these? Our Lexus dealership doesn't touch these items. The owners manual doesn't address this feature and their wiring nor do the 2000 posts I've searched on this website. All the current fuses test out fine. Do any other features share this fuse?

 

Typically when these are installed there will be a fuse in line from where the power was tapped for the monitors. Follow the wires that run out of the seats. I'm guessing they might run into the bottom of the center console or under the seats where the power was tapped. You may have had the power wire connector break or blown a fuse. The fuse will be in something like the box attached to the red wire in the attached picture.

 

Thanks. You were right about the fuse location located at the rear of the center console. Only problem was that the fuse was okay. When observing the technician probing the fuse with his (car battery operated) probe then both monitors' power buttons lit up with the key ON. The technician never removed the fuse! There was no charge to me since the technician didn't know what fixed the problem. I have no explanation but suspect something must have reset something when he was probing the fuse.
At least the next time the monitors lose power I'll know where to find the fuse.
