Why doesn't my disc play in my blu-ray player?
My device turns on, but the disc I am trying to play is not reading for some reason.
Depending on how old or new the disk is, you should first try to clean the disk itself with some proper disk cleaning material you can find a suggestion in our troubleshooting page. Otherwise I would buy a disk cleaning set from your local supermarket. If this does not solve your issue then your disk reader can be dusty or just malfunction you can buy a disk reader cleaner at your local supermarket. If these do not help again check out the troubleshooting page link above.
