Finish replacing them and get back to us, I think you'll find it works fine now.

but what do the rest of the capacitors have to do with the screen being black like this? I will do what you guys say, but I just don't understand why do I need to replace capacitors that have nothing to do with the screen. I'm not gonna argue with you guys and I will continue to replace all the caps. I am just curious to know why do all the caps afffect my black screen issue.

I'm glad I got the sound and the power back. So the only thing that's left to fix is the black screen.

Thanks so much guys! I will keep updated.
