Help with MacBook Air Screen Going Dark

Ask them to supply photographs of the liquid damage.

Have you let anybody else use your Mac unsupervised?

 

Aarrgh I had my long reply posted just as the forums went down for maintenance. Just to jot down the points:

1) Escalate with Apple Support via telephone

2) Request photographs of the damage: liquid corrosion on PCB will be immediately obvious, whereas one liquid sensors might be covered as goodwill

3) Post the photographs here for our consideration; without having an opportunity to personally see the liquid damage, we're a little limited to see what the situation is.

Best wishes & speak with you shortly.

 

Why would Apple react differently when a customer looks at photos of the damage?

I think OP is either not telling the whole story or cannot remember anything...

 

Who knows, Adam! The important thing is that it's all sorted at no cost to you.

Best wishes and hope you have a wonderful rest of the week.
