Try igfxagdc=0 + platform-id only (00001659 or 00001b59)

do you have a monitor, hdmi that you can plug in to also test when the screen goes blank?

Thank you for your response.
I using platform-id = 00001B59 and device-id = 1B590000 with -disablegfxfirmware boot arg. It's working with HDMI (my TV). for LVDS I got black screen with blacklight.
How to convert from HDMI to LVDS?
