You might want to put a little more info about what lcd driver board you have, If you need info on hooking up to the pie zero board this may help >

As in my pic above run the composite cable from your LCD board to the pi's TV pin hole on the left and the ground on the right, You also need to find out if your board runs on 5v or 12v if 5v simply run it to pin 2 on the pi's GPIO if 12v only you need a booster board that will boost to 12v.

That screen will also require the following modification to run off 5v

It is definitely hard to solder that wire there, think i accidently bridged something then my pi0 would not power on but i have removed the wires from the pi0 and it's fine..

Yes, you'll need quite a small solder tip. I think you'd be OK to remove that chip and solder onto the pad directly, but I haven't tried it.

I removed the chip as it was causing a bit of screen noise plus it was easier to solder with the chip removed.
