The laser in the Sony SCD777ES is notorious for failing. You can find the laser for sale on ebay at around $150 to $300, but some would prefer to just shelve the unit rather than replace the laser. I had mine replaced by a friend in one day. It can’t be that difficult. In any case, there must be one owner of a failed unit that would be willing to part with the puck. I'm hoping that if anyone feels generous, they will respond to you via this thread.
