From somebody that sells Samsung parts, Google your part number.
One thing I want to mention, is to ask if you're sure you have discs that are formatted
to work on your machine. I've been running into a lot of guys returning from overseas
who bought machines or discs in countries with different formats. Just checking to
see where you got your machine, and what type of discs you're inserting.
Some guy gave me several DVD's he bought in Germany, .... they won't work on my
U.S. destination machine. You don't need to reply to me here, just take a look at
your situation there, and make sure you've got compatible equipment and media, before
changing-out parts in your machine.
