Would a broken display assembly stop the macbook from turning on.

Hi I recently had a macbook that died which would not turn on at all.
I been advised that the macbook display assembly needs replacing.

However i would of thought even if the display is broken the keyboard would still light up as well as the touch bar and be able to output to an external display. I got a felling that when the repairer look at the laptop they have disconnected the battery which might of reset the smc which I did try and now the macbook will turn on.

For confession the display shell has got a couple of dents which I did cause, however I just got gut feeling, which I might be incorrect on they are looking for an excuse for a expensive repair job as I can live with a few dents.

Was the screen working after you dented the shell?

If you suspect they aren't honest about the only thing you can do, assuming you don't want to take it apart yourself, is take it to a different shop and get a second opinion. They could disconnect a cable and you'd never know until it was checked.

A damaged display would not stop a MacBook from booting. I have purchased a couple of MacBooks (1 Air, 1 2014 Pro) with damaged displays and they work fine with an external monitor.

Hi the laptop stop working after a power spike i think. In terms of the physical damage(dents that was done which was my own fault. The screen itself is not damage just the trim on the bottom is cracked.

I was unable to check the display was damage because the laptop would not power on but it would not power on before i dented the display.

I did try to reset the smc and pram before sending the laptop to the repair shop assuming there was a problem with the logic board, however I did read on the internet someone had the same problem with a macbook and resetting the smc did not work until they disconnected the battery and the laptop started to work again.

I just found it hard to believe that a damage display assembly would stop a laptop from turning on in the first place. They are advising me the laptop is running now but i believe one the first things they do is disconnect the battery and that's resolve my issue, from their stand point there's nothing to fix apart from the screen which I can live with the cosmetic damage and I got quote from Apple that's cheaper to replace the display assembly then they want to charge.

If they say it runs without the screen working, that settles that part of your question. The cables are fragile, they might have damaged one. Do you have evidence you can show them that the screen was working before?
