Conia M370 DVD PLayer - Won't play DVD will play CDs

[ziomarco999]

Last Saturday my Conia M370 stopped playing any DVD - movie, music etc. Yet it will play CD ROMs.

How do I test the device to determine the fault?
Does anyone have the test and fault codes I can use via the remote?

Does anyone have all the codes to check the device using the remote?

I believe that they use a different laser for DVD as opposed to CD, perhaps the DVD one has died.
