screens isnt working

[MarioOwnsAll]

Ok I had my n64p working fine before but the batteries were rattling around in there and disconnected a few wires. I re-soldered everything and now I get audio but no video. The leds light up but there is no picture. Eventually the screen will start changing colors.

pictures? What are the colors? Red, Green, Blue?

Make sure that when you soldered everything back you didn't mix up the three wires and solder a speaker wire to the video

Also, ths may sound wierd, but I found the video to only work when power is hooked up to certain places at certan times. I would de solder the power to pin 1 and move it to the regulator or another spot where you can put 7.5v. This always fixed my problem. Some times my video worked when I put power to the regulator sometimes when I put power to pin or PS1 and PS2.

yea I made sure of that, I was looking at harshboy's n64p wiring diagram and I saw a fourth gray wire, is that needed for the screen to work?

Look at my post above I edited it. Also, yes that is ground for the screen you need it for the screen to display audio.

So, you added a wire to pin 4 on the screen and then soldered it to the N64 and it still doens't work?

not sure if the grey wire is needed or not but it was working before and I didnt have the grey wire attached

[Designer noob]

The greay wire is needed, its called ground. Without ground no power can get to your screen. The ground completes the cycle of power. Without it there is no cycle.

so without this wire would the speakers still work? cuz the leds on the screen still light up

lol, nvm forgot about that. You must have a ground somewhere else.

I would try puting power to different power inputs on the screen this has always worked for me or wait for someone to help you that is a lot smarting that me.
