Alright so last night I took off the step-down chip and started wiring everything. Now I'm getting no response from the screen, and the AC adaptor starts buzzing when it's connected to the header-pin spots.

Oh nice! I think i've figured out which piece is which for the chip, not sure about the header pin spots though

nm found the resistance on those with a potentiometer, although there's a three header pin spot section that also shows resistance

sounds like its underpowered. You might also check if your screen can be modded to take 5v. I saw a thread where some 12v screens go through a regulator and actually operate at 5v internally, you just have to find where on your screen to apply that five volts directly.

Screen flickers on for a bit every 2 seconds. Not sure what else to try.

i'm not really sure where that is, do i have to de-solder the RF box?

guess not, just needed to pull that shield off the bottom. hmmm

At 6v it worked ok. would flicker sometimes. to be safe I'd say 9v would be choice. I thought the Mrs ran off of a higher voltage? you can solder right to the inside pin if the power port

There is no 12v supply in a NES.  You can always drill a jack for the screen power and run a second psu to it.

This one says it runs on 12v DC, and I dunno where to get that power from. I tried to hook it to the ground / 5v parts of the second controller port, it would flicker on for a second but nothing really happened

I haven't played with the screen in a while but I think it worked fine at like 6v

I've powered these screens in just about everything I own with a video out (except the NES). As long as you don't mix the ground/power, you should be ok. I believe these cheap-o screens can take anywhere from 5v-12v.

I'm thinking the power on the controller port should be good. I also think just having the screen resting on top of the console is the easy way out.

I see your "integrated" screen, and I raise you a NES Control Pad + LCD in the shape of a GameBoy!

How can you create a standard plug socket for the screen, as my research suggests the screen's power supply is two wires (Red and black). I haven't done electronics in years and don't really want to kill myself in the process haha.

Any recommendations? Would love to have a mini screen with my megadrive.

EDIT:

I'm an idiot. Just realised you can buy power supplies for them.

I like where this is going.
It needs a little more crazy stirred in, just to make it interesting.

Is there a tutorial on this anywhere? I keep finding links to tutorials that also involve making the NES portable, and I want to make one that powers off the NES without frying the screen.

The poles are backwards from standard plugs. email me with any other questions bout it (12ianma@gmail.com)
