Hey guys, I am really new to this modding scene and I have to admit it's becoming addicting, I recently installed a backlight and bivert module kit to my play it loud clear DMG and I noticed the shades are not showing up. I took it apart and was checking connections and as far as I could tell it looked fine, the odd thing is if I press down on the module three of the four shades will pop up. I'm not really sure what to do at this point, I will post pictures down below of whats going on. Thanks for the help.

I didn't think you needed to cut anything for the chip to work, I'm not really sure what he did to fix it. The comments say he ran a wire from a via to the cpu

you just need more solder on VCC, pin1 and pin3. the reason the correct shades show up when you press down is because pushing down on it is making a better connection between the points on the chip and the points on the board. VCC looks like a cold joint. just reflow some more solder into those points and the problem should resolve.

Okay thanks for the reply, I'll see what I can do later and I'll report back

Do I need to make sure those holes are filled and flat with solder?

I never have luck with those boards, have gone to using chips mounted on a generic breakout board and wiring the connections.
