I have a Sony Digital 8 TRV 720 Handicam that no longer works.  Is
there a Sony Repair Service Center I can send it to for an estimate? 
At first I thought the heads were dirty and tried to clean it with a
cassette cleaner.  Now it will not play or record but I can hear it
running.  I'm not sure if it's worth fixing or just getting another one
on Ebay?
