820-3332-A Boots and runs great. Screen suddenly goes of. No backlight, no picture.

Like the subject says. Board has reported liquid (coffee) damage although I can't see anything.

Machine appears to still be running ok. HDMI port appears to be damaged so can't test external screen.

Thinking I'll start by investigating SMC_LID signal?

Check external with thunderbolt to VGA adapter. Or clean it up and hope Apple will accept it under the GPU recall.

Thanks.
Couldn't get an external screen to show a picture despite it detecting it was plugged in.

Cleaned up and returning under the recall program.
