Before you use this trick should first check lcd light path as shown below, since it is not possible to create a path breaking lcd lights went dark.
After you check the track is ok , but the lcd lights still out ,
the possibilities can also be diodes transistor
If you have transistor and diodes are still good can be changed on the V2401 and V2400 circled above picture , but if you do not have anything, can use without transistor and diodes , .But before you dispose of used V2401 and V2400.then made a jumper as shown below
The trick unloading lcd , lcd lights dislodged and create parallel jumper as shown above ,
the trick is 1000% successful
