remove and replace rf box

[ssnik992]

Could anyone give basic instructions on how to remove and replace it? I'm not getting the book cuz I'm cheap and am only doing this once. Also,could i have a list of the tools needed?

You're replacing the internal RF unit in a frontloader, right? My suggestion is to de-solder it from the motherboard and replace it with an identical one from another NES. You would need a soldering iorn, copper solder wicks, and solder. Just heat the existing solder with the iorn, use the wick to remove it, swap the rf units, and solder the new one on.

Don't take it from me, I haven't fooled around with game systems too much (aside from repairing connections).

I meant I needed to get a video amp and stuff on it.

Sorry.

You should find all the info you need there.

Could I have some instructions on how to make the video amp, as I'm a first-timer.

Here you go:



If you liked this diagram, then you should buy the book "Hacking Video Game Consoles" by Benjamin Heckendorn. It contains a much better drawn version and much more!

where is +5 volts? Do you mean the pin on the nes board or something else?
EDIT: Can I also have a diagram for a power thingy? Sorry, I don't know how to describe it better.

Here's a more detailed picture:



Hopefully it's not too confusing. The part where it shows multiple wires going to the jacks on the pocket tv looks kind of like the wires are all connected together-they're not. The ground wires would actually go to the pocket tv's ground. And the power, video, and audio wires would go to their respective places in the pocket tv. (If you're not using a pocket tv, it should still be similar.)
If you need more detail about something, feel free to ask.

Just a note on that diagram, if you want to use the original nes power switch tie power into point 1 on the nes instead of point 3, then tie points 2 & 3 together.
The only problem with that is there may be some quesient (crappy spelling, I know) draw

I tried wiring this circuit up, only without the 220 Ohm resistor (because I followed this http://www.classicgaming.com/nestable/i ... ematic.gif only with the 7805 regulator). I also put power to pin 1 and tied 2 and 3 together to use the original power button. I also spliced a connector into an SNES transformer for power. I got it all together, and the voltages seem to test correctly, however, the system doesn't work. I get a solid power led, a blank screen, and a hum over the audio and that's it.

I have a hunch there is something wrong with the main board. I got it from a friend, who got it from someone else, and I never saw it work. I tried it and was only getting static, that is why I did this. I saw some water damage in the RF/power unit and figured I could replace it.

Any suggestions?

Perhaps get a board off of some used gaming site.

maybe you switched up the audio/video, I always get a hum when I plug em in backwards on the TV.

But I'm retarded, what do I know.
