Getting a C 13 70 disc is dirty message only for DVDs that I'e burned recently. I bought a new pack of blank DVDs, the same kind I've always used, but every movie I burn on these new ones, they won't play and I keep getting the error message

I have a brand New Sony DVD player and we barrowed movies from the library it keeps saying c 13:70. Disc is dirty. We tried everything. What would be my next step to resolve this issue? We picked the movie up on this past Saturday

Hello, welcome to Fixya!

Was this player playing previously? And how long have you been using this player? I suspect the lens of the player. Once the lens of the player becomes weak, it won't play discs any longer.

The first thing my mind goes to, is the lens. The lens id responsible for reading/loading data on discs. So if the lens is unable to read the disc, there is no way the player is going to play the disc.

To confirm if actually its a laser problem, insert an Audio CD into the player and see if will play. If it plays, then obviously, your laser (lens) is weak. But if it doesn't play Audio CD, then it might still be the laser (lens) or probably, a mechanism problem.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all DVD discs again.

Good luck.
