Pentax zoom 90-wr and two Olympus Superzoom 105R

Three cameras for sale The Pentax zoom 90-wr: is functioning, most of zoom buttons no longer work and the door has issues closing, besides that it works. (ask for video reference to see door and zoom issues) 2 -Olympus Superzoom 105R: not functioning. Neither of them turn on. I haven’t taken then to see a repair man so I have not clue what’s wrong. They used to work perfectly and both just stopped turning on.
