No backlight after replacing screen

Hi guys,

I've had the same problem with my macbook also no backlight. I've bridged the fuse and it's reading 8.0V so that is not the problem. Can anyone else give me a push in the right direction.

Much appriciated.

carefully check your LVDS socket and the LVDS connector for any damage. Often a short on the logic board can damage these parts so even if the fuse is bridged power wont reach the screen backlight.

Ir might be burnt out on the display. BTW bridging the fuse is risky, you can burn out other parts of the board (maybe start a fire).

If this Answer is helpful please remember to return and mark it Accepted.

Hello machead3,

thank you for your answer, could you please explain what you mean with "IR".

I'm not the one who is bridging, a friend of mine who has a lot of experience with this is performing the labor.

Is there any way i can get a schematic for this model?


I lost the source but someone reported doing this (bridging fuse) then seem surprised that smoke was pouring out of another spot on the board. Bridging the fuse isn't the problem...that the fuse can no longer function is the problem.


What I meant was the replacement display also has a defective backlight.
