My sony bds4100 bluray player wont play any discs

SOURCE: blue ray player wont play blue ray ''Kung Fu Panda'' disc.

i fixed this exactly as previous posted solutions, however a couple of points.
a) recordable CDs work if you don't have a DVD burner.
b) I didn't have a CD burner that would do an "image burn", I downloaded a free copy of "Express Burn" and that worked fine. The disk needs to be "finalised" or "fixated", it should do this automatically, or it may be a tick box selection.
c) I got a "No DWLD 09" when I put the disk into the player. I found this was an incompatibility with the CD-R (Maxwell) I was using. I changed to JVC and it worked fine.

Did the Live Chat with Sony, and they said if you reset the unit (unplug it for a minute and plug it back in) that should fix the issue. If it does not (in my case, it did nothing) the unit needs to be sent in for service. I'm taking mine back to the store in hopes for a refund. Good luck!

After variety of different tests and findings I have resolved this issue. It appears that the DVD burner was not in good working order and the DVD player was not at fault. Thanks you to all who answered and responded to my problem. Many thanks.
