Today my controller came in the mail for the Dreamcast I bought a week ago.  I turn it on, set the Dreamcast Date and put in my CD ( only thing I have to test it), and it does not read it!  I searched around on the internet and started messing with the potentiometer ( the screw nest to the ribbon cable) for an hour and with no results.   This is one of the launch Dreamcast's. The question is should I order a new lens assemble for $20 for a grand total of $37 spent on this Dreamcast, continue screwing around with the old lens assemble, or just get a new Dreamcast?
