MacBook 1286A - Black Screen; replaced screen assembly - still broken

Hi,

Last week my 2012 MacBook Pro's screen died. I brought it into the local Apple store, and was told that the backlight was broken - we did the flashlight test. I ordered a new (used) screen, and after replacing it - it's still a black screen with no backlight.

I've:

-reset the SMC

-reset the PRAM

Nada. The keyboard lights up, but the apple on the back of the screen does not.

Any ideas??

Hook it up to an external display first and let's see what we get. Did Apple run any specific tests or was it just a best guess diagnosis?

I'll bring it to work tomorrow to try that out - will report back in the morning. Thank you!

Forgot to say - I believe it was a 'best guess' diagnosis.

@trumpetcharger backlight issues are 99% of the time related to the logic board or a damaged LCD cable on newer models; you only see no backlight issues caused by the LCD if it has had liquid spilt on it the majority of the time.

I would recommend taking it to an independent repairer who has a variety of test parts, and can determine the cause of the issue. Ideally it is best to take it somewhere where they do logic board repairs; since it is highly likely this is the cause.

Ok - hooking it up to an external display does work.

Reece - thank you. I'm guessing the Apple store would charge a ridiculous amount for a repair.

This may beg the question - on a 5 year old machine - is it worth it to get it fixed?
