Hi, i HAVE A 2003 HONDA ACCORD COUPE. MY TOUCH SCREEN WAS SAYING DVD DISK ERROR SO I UNPLUGGED THE BATTERY AND NOW IT IS SAYING CHECK DISK. PLEASE HELP HOW DO I GET MY TOUCH SCREEN BACK UP.

I got the same problem and have been able to fix the issue. Cleaned the lense and everyhting.

Dvd disk error and check disk error both are same error.The name is different.In both cases the lens in the dvd unit needs to be checked.The lens is either moved from its position or getting blocked by any dust or any dirty stuff got stuck up on the thin lens glass internally.
In some cases the lens is cracked so the lens assembly needs replacement.But first try cleaning the lens with a dry tissue.You can also try blowing air from air blower first.Blow air in the unit where the disk is inserted/placed.Then check.If still same then the unit needs to be removed out to disassemble to clean the lens manually and also this will help to know if lens is cracked or faulty.

Thanks. keep updated for any more query.you can rate this solution and show your appreciation.
