I have old electronic devices with use aluminum electrolytic capacitors and manufactured in the early 90s and early 2000s and my home conditions temperature of 33-36C, humidity 57-67% and energized devices at 220v AC 60hz if I energize all these devices under these conditions for 1 hour (60 minutes) what is the maximum interval and frequency to energize them again and prevent failures in the aluminum electrolytic capacitors caused by disuse?
I have CRT TVs 29" Philco and Toshiba, consoles Snes JR, Snes Fat, PS2 Slim 90000, power supply 5v and 12v, tvbox T95 Max Plus, DVD Drive Sata internal

Its probably enough to power up once a year to do any re-forming of capacitors, not sure for how long though, less than an hour I suspect. Al capacitors will gradually dry out, and this is temperature depedent. Other things can deteriorate as well over time, not just electronics, but glues and greases and rubber belts etc.
Not only that, it is very much dependant on brand / series. Industrial grade capacitors usually last much longer than NoName or cheap capacitors used in household items. There is simply no way to predict, how long these common items will last (you can do a statistical approach, but that is quite complicated, and will just give you a number - but that does not mean your item will last that long). If you are experienced in electronics and you want to items to last as long as possible, I would check the TVs for bad soldering, google for common faults on the consoles and leave the rest until they fail. A yearly powering up procedure is IMHO pointless, it's better to repair them once they fail.
Not so sure if repairing them once they fail is pointless. Keeping stuff and never using it is pointless. Anyway, when not being energized the semis may not have a nice time when caps fail. So final result is quite often that the device is EOLed definitely. This means that storage and stuff keeping space occupied has been useless. At least a few of the items on the list will not survive storage for a longer time as it is consumer grade stuff superseded by newer consumer grade stuff. When the newer stuff fails taking the old stuff out of storage might mean again a defective device. It is a circle costing time, care and energy just like wanting to keep unused/superseded stuff alive. Maybe the gaming stuff keeps a certain value and storing these water/dust/insect proof and energizing them once every half year has sense. The trouble with reality is that rubberized plastic will become pudding, plastics will become brittle/discolored etc. No one & nothing wins from time.

It is a human deficiency. Hoarding old piled up smelly electronics that will very likely be discarded remorselessly after you are gone. Helped out a few times, those left behind in despair where to leave that pile of garbage. It went nicely through the grinder for a new life as electric toothbrushes and game consoles. While sorting out one may become seducted but keeping such items will often result in those items again being discarded. Regret because of recycling "valuable" stuff ("destroying" in ones mind) is afterwards a relief resulting in a good impulse to ones self-confidence.
The pattern is that oversight is often lost, nothing gets serviced or repaired, many items are bought double or triple etc. so it would help to find the strength to keep only a few items and keep these in top shape. By using them or letting others use them.
