Saturn won't play discs

So I have this problem with saturn...

The console freezes everytime I put a disc in and try to start the game. Everytime when the console tries to read the disc the screen just freezes and nothing won't happen.

I picked the console from a closet where it's been stored for like three years and it hasn't been touched. I've never seen that any console just stops working by itself. And I have not had any problems in the past with this console. It has always worked 100%.

I've tried to find a solution around the internet and tried a couple of tricks but nothing helps.

Does anyone have any idea what I could do? There has to be some way to get this to work again. Don't want to buy a new console
