Hi guys,
i have a mbpro mid 2009 13’, my screen lights are not working well so i am thinking of replacing the whole display. I found a mid 2010 with a broken motherboard, i am thinking of buyying it and use its display. The only question in my mind is their EMC numbers are not the same. Mine is 2326, the other one is 2351, do you think the parts match with each other? Both their model number is A1278.

If your display image is messed up you can transfer the LCD panel to your system following this guide MacBook Pro 13" Unibody Mid 2009 LCD Replacement
If your issue is the backlight then that’s going to take a bit more as thats likely a problem within your logic board.
I’m suspecting your LVDS connector on the logic board is the failure here. Lets review the schematic
And here is the returns on the connector
Here’s the power source these two pins which are wired together
Here’s a more detailed view of the connector
So as you’ve lost half of your LED backlight strip which sits at the bottom of the screen the question you need to test things using a Ohm/Continuity meter is if circuit is viable for each return. I would use a spare LVDS cable to plug in so I can then check each path. In most cases I don’t need to do this as corrosion on the logic board connector often is a tell-tale sign the connector is bad.
Likewise, after unplugging the LVDS cable I can also check the LED string/cable connection as the display its self has a connector for the cable that can also get damaged and the cable could be bad as well. You should see a resistance on each and they all should be the same.

Hi Dan,
Tnx for your response, i add some photos for the issue, tnxx
hi, did you solve the problem? Does the EMC have to be matching with the original mac you had? I have the same problem and was wondering if it mattered

@Yoav Barnea - Yes! The display needs to be the correct one for the system! This is the required LCD panel MacBook Pro 13" Unibody LCD Panel and here’s the guide MacBook Pro 13" Unibody Mid 2009 LCD Replacement
You may have an issue within the main logic board! As the the backlight is made up of multiple strings so if you have the same issue as Emre then I would inspect and measure the voltages on the connector before I replaced the LCD. As more than half the time it’s corrosion that does you in!

You stated the display lights are not working are you speaking about the backlight? Or is the image distorted?
How about posting a picture or two so we can see Adding images to an existing question
