Why the screen is not turning on

I recently changed my old MBP logic board and after I reasembled together the screen is not turining on and also only 1 fan is running, I believe one fan is broken but I’m unsure why the screen is not turning on and no turning on sound.

These have GPU issues and use older CCFL displays and as such, use an inverter. This hasn’t been a problem on a large scale on the LED Macs.

In order to rule out a bad GPU, check for an image with a flashlight. If you see an image, the GPU isn’t at fault. If you do not, your new board has a bad GPU.

If there is an image, you will need to check the panel and inverter - the inverter is cheap and easy to find, so I’d start there. Refer to this guide to change the inverter.

If the invterter doesn’t help, your screen has a blown backlight. At this point, these screens are rare, expensive or aren’t much better in terms of lifespan - I’d scrap the notebook and get a newer model with an LED configuration or buy a complete assembly and swap everything out at once. The 2008-2009 Unibody models were the first ones to use these panels. That said, if you can get a 2011*/12 and future-proof yourself in the SATA standard area, that’s the way to go - a lot of modern drives are no longer legacy system friendly and pre-’11 machines are capped at SATA II :-(.

*13” only; 15/17” have GPU issues
