You should have a winder to bring the stabilizer jacks up manually. The fuse should be in the power distribution center.
As for the tv bracket, there isn’t one. The sticker is there to show where Puma put appropriate structure to mount a television. From your description it appears that your unit was designed for a swing down type mount.
