Sorry man didnt mean to horn in on your territory! ;) Actually I do have my own thread, I posted it in the Hacking Videogame Consoles - The Book forum, before I realized there was a separate NES forum :roll: My thread is Newbie needs troubleshooting NESp connections, screen, video. I'll stop posting ...

Ok ill go take some now, give me a bit and Ill PM you with them.

Yeah I followed all the diagrams and instructions in Ben's book exactly. All the parts are identical to what he used. What do you want a pic of? I'll get you anything you need to see what's going on

Ok I tested and yes I do have nearly 10 volts going in to the 7805 on the NES motherboard. And I do have +5 volts coming out of it, so that component is good. I also tested and have +5 volts going into the motherboard (frmop the 7805). However when I tested the Video OUT port on the NES motherboard ...

So I would put the negative tester on the ground? and the positive tester on the +5 volts going in or out? which one does the positive touch to?

Wow lucky bastard! I very well could have the same problem you're having, or HAD, a bad 7805 on the NES motherboard. Do you know how to test that component individually so I can see if its shot or in working condition?

Good for you! Seems like your problem was simple and is easily remedied. I on the other hand believe i Had a bad psone screen so i bought another one and lo and behold i finally get those green bars to show up! This tells me the screen works fine. But I still cannot get a video signal. I think I ...

I do have a multimeter, the problem is I'm not really sure how to sue it or where to test. For instance I don't know which end to put where (positive, negative) when I'm testing the connection between two components/spots. I still get confused easily since Im new at electronics the flow fo the ...

Hey minkster, keep at it. Ive been reading your thread and it look slike youre overcoming a lot and youre almost there! Its nice to have some help and guidance along the way too. Ive been having the same problem you have. The screen lights up but no video. Im going to go check all my voltages right ...

Would that interfere with the video signal? Im having the same problem...

I connected the ground to the metal on the NES motherboard and still nothing.....

Ill give that a shot in about an hour

I soldered the center wires to the video out. There is a sheath that surrounds those center wires and then a bunch of other wires that surrounds that. I didnt connect those wires to anything, but youre saying those wires should be connected to ground? I'll give that a try but shouldn't I have gotten ...

Center pin of what? Outside ring of what? Which wires do you think I may have reversed?

Hey mastergamer, I think Im having the same problem with my NES. No picture/ni video signal. I'm still trying to troubleshoot that. Was yiour video EVER working? Mine never has, it looks like the onlyt hing going on is the LEDs light up. i dont even get those green bars on the LCD screen when I ...
