I'm sorry this took a bit longer to answer than it should.  I don't have a 
SV-5000 to work on (and hope I never do), so I cannot say if the technique 
I described for the SV-7000 will work to eject a stuck tape.  I can say 
that even in the case of the SV-7000 that technique only works to drive the 
stuck tape out of the machine - while it is unplugged and laying on my 
workbench, cover off.  It is no permanent fix.  For that someone has to 
replace the burned out diodes and resistors and transistor in the drive 
circuit. I've been sending the units back to the Samsung dealer.
