Question about Samsung DVD-V4600 DVD Player/VCR
It is possible that the Switch mode power supply is faulty. The Switch mode Driver can be faulty.If the fuse has blown check if the rectifier, the main filter capacitor or the driver is having the short from a test with a multimeter. The possibility of the Oscillator IC or allied circuit can be also faulty. I some cases the SM transformer also gets short and fails to work.
Replace the shorted component for the SMPS to work. The DVD must power on now for the DVD to be released.
Alternatively after opening the top lid you can get to open the top of the CD holder to release the DVD.
If there is major damage to the power supply unit , your can replace with a full unit that must be ordered.
Hope my advice helps

Tips for a great answer:
test all power and data leads that attach to your hard drive SATA
the leads from your (motherboard to your hard drive) make sure they have a secure dust free connections and are not faulty
make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty
even something as small as faulty fan lead can cause you problems
computers need all of the data and power to travel through every working device and to have an end for a computer to be able work properly
a motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive check all power and data leads make sure they are securely seated even the cd/dvd drives need to have current go through make sure these devices are working
check the CPU central processing unit make sure it has thermal paste and dust free secure seating
also check your computer ram modules and cmos battery make sure it has charge and they are dust free and securely seated some motherboards cmos batteries are soldered in
hope it helps
