Dimmed screen problem still after new inverter board and cable!

[mollyt23]

OK, so I've searched the internet for additional solutions to my problem. My Macbook was dropped and I thought the screen was broke but soon after realized that I could see my desktop and everything worked when hooked up to a TV. I swapped out the inverter board and cable and there was not a difference. My laptop is a Macbook "Core 2 Duo" 2.4 13" (Black-08)

When you dropped your MacBook it may have dislodged a cable that connects the inverter board to the display backlight. You state that you changed the inverter and cable, but which cable? There's also a chance that the backlight itself was damaged in the drop. I wouldn't spend too much money on such an old MacBook which is only worth maybe $150.00. Go to www.ifixit.com and do some more trouble shooting.

I'll have to double check all of the connections. The cable I replaced was the inverter cable.
Is there a quicker way of checking my repairs that doesn't include putting everything back together to find out it still doesn't work? I followed the instructions here https://www.ifixit.com/Guide/MacBook+Core+2+Duo+Inverter+Replacement/1497#s2548

You followed the right instructions from ifixit but unless you get back in and check everything again, you can't be sure.

I've seen other people mention a backlight fuse? Could this be possible?

Yes, it's possible. However, locating the fuse is not easy since it's not an ordinary fuse. My understanding is that it's a fuse-resistor (a small resistor that acts like a fuse to protect the circuit). You'll need to do some googling to try to find out where it's located at.
