No display or backlight
I bought a MacBook Pro early 2013 from new. I’ve had various issues and managed to repair most of them myself.
However!! While the laptop was resting on my coffee table I managed to knock it off and the impact smashed the display The image was distorted but the screen still lit up and i was able to connect an external monitor successfully.
After some time i bought myself a new screen from eBay. I swapped the display but forgot to disconnect the battery cable and the laptop powered up while my fingers were on the motherboard! So, i put the new monitor on and powered her up, but i now have absolutely no display or backlight. I do hear a chime though. I ‘ve tried numerous resets and swapped the old screen back, but none have cured the issue. I feel i’ve damaged the motherboard when i swapped the screen.
We’ve been through several wars together and with all my data, i would love to see her alive again. Could anyone kindly help?
