NOAC wont start

Just a FYI,

After looking over my connections with a microscope, I'm pretty sure I destroyed them when I was desoldering.

I'm going to purchase a new NOAC and try again.

Also, I just bought a Cold Heat soldering iron and all I have to say is STAY AWAY FROM IT!

Hey, if you think it might still be good, besides the solder traces, would you sell it? It might be possible to fix the traces. So as long as you didn't connect the 20V to it, it might still be fixable.

Thanks for the cold heat warning. Makes me really apreciate my weller iron!

I <3 my Weller iron!

*hugs iron*

*sizzling noise*

Yeah the Cold Heat iron isn't any good for this kind of work. I use a Weller WTCPN base with a TC201P iron. (it's about 65-70w) It heats up in an instant! It deos the job for how I solder (I tin everything), and I've done everything from wiring to PCBs to jewelry. (Jewelry is damn hard to solder and have it look acceptable

)

Anyone ever solder copper pipes before? The only problem is that you're using a propane torch, and it's really REALLY easy to melt fiberglass insulation with it... and wood burns so that doesn't help...

I'm pretty sure the actual traces on the board are ok, just the pins that are bad. Concidering a new SuperJoyIII from gannon is only $18 I don't really see how much I could charge for just the chip. Let me verify this week that i'm correct that the pins are screwed and i'll give it to you for paid postage (or anything cool you might want to give up

)

As far as the Cold Heat, I only bought it because I burnt the hell out of my hand on sunday and seen the commerical that day. My biggest problem with it is the tip is split into two parts (positive and negative) and both parts of the tip have to be touching one conductive piece (like solder) before it gets hot, so it makes soldering or desoldering little points near impossible.

I finally picked up an multimeter so I can continue on this project. Right now I have only the video +5v, ground and video connected.

It seems like my battery pack is only pushing about 4.97-4.98v I'm assuming thats ok. If I hook the multimeter to my positive and negative solder points I am getting the same so I know those points are ok.

I guess my question is how many volts should I see going to the compostive video because I'm still not seeing any video. I desoldered the famicon connector. I am using the Super Joy III w/ included games. Could the built in games not show up because I desoldered the famicon connector?
