Almost has to be a Maggy. Controls are interesting.
Up front you can find
1) brite
2)contrast
3) on/off vc
Usually behind a door:
4) H hold
5) V hold
6) tone
If it has a good amp maybe:
bass & treble instead of tone, aux in.
Fine tune may be separate & on/off also.
Fringe lock or local/distance another poss.
You can drive it up to 9 controls.
