One day my screen started flickering then it went black. I thought the lcd / led screen was dead but on further investigation (shining a light through the apple logo) I found that the screen is working fine its the backlight. Now I can not find a clear fix for this. Could I just buy a new screen and all will be well or is it something else I need to look at thanks
Your system uses LED’s for the backlight system. On your main logic board is a driver chip (WLED) which likely blew. Here’s a simular question: Location of the WLED driver. You may want to also review the IFIXIT teardown for your system: MacBook Pro 15" Unibody Mid 2010 Teardown.
Do not forget to check your backlight fuse.
To know if it’s the backlight you can hold a flash light up to the logo on the backside of the screen if you see a faint image of your desktop icons then you know its the backlight or not.
