Hey folks, I just installed a LED backlight! It worked great but... I wanted to remove the coil (transformer) for more battery saving and now the contrast wheel doesn't change the brightness and I believe the screen has no image. Is there a certain way to remove these or other components to remove or any bridging that needs to be done?

I removed the coil for this and now I can't adjust the contras I was repeating what I've done for game Gears but had no luck. Do I need to put a jumper wire somewhere?
