I have a Sony DVD Player Model DVP NS575P. It was working fine when last used nine months ago and now returns message "C:13:70 The Disk Is Dirty" with every DVD including brand new movies. How can I repair it?
DVD Player will display this error if disc is dirty, scratched, or inserted incorrectly, preventing the laser from reading the disc. Also, clean the disc and ensure the disc is inserted properly. This also can be an indication that the disc you are attempting to play is not compatible with the player. Information about supported discs is mentioned on page#8 of the instructions manual:
