Yes! Depending on the version Saturn it is, the door interlock can be defeated with something as easy as tape, or worst case scenario, a dot of solder. Then it will think the door is always closed, which isn't perfect, but is vastly preferable, because games will play.

However, if you have an exchange option, and can simply exchange it for a working unit, I'd try that first. If you got it cheap due to the malfunction, then I'd try to fix it.

Nearly half of my 30+ systems were acquired broken and cheap, and then repaired. It's a good way to get hardware if your a bit handy.
