You are going to have to give us a model number and a better description of it's condition. Chances are it's not worth the trouble of trying to sell it. The only laserdisc players that are worth anything are the Pioneer's and only the best ones are worth a lot.

Unless it's one of the following models I'd list it on ebay for 20 bucks and hope for the best.
