FIDES do not cover the FMECA, hope someone could help you anyway.

Advice : In order to help the non french reader you should post your question in English

Dear Bentahar,

The ISO 13406-2 standard defines fault classes for a LCD screen. It might help.

If you need somethig more detailed, as screens are indeed complex sub-assemblies, you will need a specific analysis (for example: a detailed FMECA of the screen...).

Regards,

Lambda
