LCD backlight connector issue (darker left side)

Hi all! I have a 27” iMac mid 2011.

It has a known LCD backlight connector fault. I already tried the re-soldering the left side connector but messed up the connection points while soldering the wires to the LCD’s LED backlight board. the connection points on the LCD for the LED’s not holding the soldering anymore ):

So, is there any way around to solder the power cable for the LED backlights from the iMac to connect directly? I couldn’t find any tear down guide for the LCD panel.

Thanks in advance for any bit of help!

That looks like you are having a lot of fun, last time the moderator remove a comment with links so i have to explain it to you. I found the schematics basically is a LG Display the model is LM270WQ1, and has a led strips. that connection goes to the led strips you can find some guys on google (I can’t share links ) that are replacing the led strips from the display panel. Now looks like you are doing crazy things there, make sure that your Backlight Power supply still working and does not have any blow fuse.

@conlledo you absolutely can share links and are encouraged to do so :-) Only thing we ask for is that you do not link to your own business etc.
