No disk error

If cleaning with a cleaner disk and solution did not work, then you have to clean the lens directly.

Remove the cover and access the inside of the DVD, unplug power first.

Use soft cotton sticks and isopropyil alcohol to clean the lens, here is a picture of the lens pickup:



As usual do the job at your risk, if you want to call for repair you can use the number listed in the owner manual.
