Hello GermanCoasterBoy and welcome to the European side of the Lair
In order to help you, we need the description of your setup of course
OK, I presume you have an Atari Dragon's Lair regarding the pictures on your website :

...and now you've this picture when you plug the game ?
The only solution would be to repair the original Philips player (you're lucky, there are here the best specialists for that hardware), or make an interface like I did (see this
post) in order to use other laser disc players like the sony, more easy to found and more reliable
Just give us more details
