All those electrical wiring and points at the back and dangling is hazardous. Get them out of the way of accidental water spill. Make sure wires are 'looped'. Better solve this first then worry about your stand ...

Dino,

Use visual inspection.

Visually survey rust stains.

Check severity of the corrosion damage, if it is just a scratch on the metal, scrap off paint around the spot, sandpaper, treat with anti-rust compound, paint over.

If the rust corrosion is severe ie. the metal has a hole,

you can repair with a metal substitute epoxy. Check out the hardware stores. Knock out the weakened corroded metal, sandpaper the metal, use anti-rust compound eg. primer, use the metal epoxy to repair (read instructions carefully).

It is rare for a metal stand structure to suddenly collapse overnight unless the entire metal is entirely eaten by rust or critical points like joints have been severely damaged.
