Macbook A1278 13" Backlight not fully working.

[cikku7]

Hi guys this my first time posting a thread, hope you could help me!

So ive got a Macbook a1278 2008 model and i spilt a little liquid on it. The backlight doesnt work all the time.
I ve read some post in the forum which say that you shouuld check the fuse of the wled driver, i checked this fuse and its fine.

Could someone guide me please because i have high hopes that it will be in 100% working condition since the backlight works at some moments.

Thanks in advance !
