I was curious if anyone had some insight on to these things, such as, if I'm to power a max 12v screen and 5v NES I obviously would wanna account for the form factor of removal batteries and it's impact on the device so I'd like to go with something internal like a nice rechargable Li-ion battery so...

so, looks like I'm desoldering and putting on a new transmitter? Bawwwwwwwwww.. well, whatever fixes this. I'll be happy if this is the ONLY problem with this thing. If it goes beyond this, it's almost worth just rebuilding the damn thing w/ only composite video and audio and just nixing all the RF.

The leads touched on the blue portions, bout 0.13v ... wait a moment, the two blue pins are ground on the left and +5V on the right. What? Ok, something weird just occured, and this never happened before. I put the multimeter to B and C and suddenly audio came out. It's producing 4v. Lemme show you...

Yes that does seem to be the situation.

From pin 10 to emitter I get 2.28v

Yeah it's inside of 2v and bout 2.43v on pin 10 and the chips ground. http://i.imgur.com/CVRqKls.jpg Hashed out the resistors and those two transistors as far as readings go. I'm at the point of throwing this board lol.. like maybe just make a different video audio output instead, it seems so murky ...

I get about 260Ω out of it, suppose that's fine eh? The other transistor on the board reports similarly as well to the last test we did with the previous one.

B to C - 0.67v
B to E - 0.67v

Yeah I have diode test, it's a Mastech MS8262 Autorange and also have a 2N3904 if needed.



The leads touched on the green portions, bout 0.23v

The leads touched on the blue portions, bout 0.13v

If I even tested the right portions.

I redid the 1nF this morning, it was indeed not connected. I added bigger leads cuz I simply couldn't see in there. Green a get a signal from the audio and the 5v pin, red, I get nothing. So it's being fed power, it's getting the audio, but nothing out. Pretty dead eh? :/ http://i.imgur.com/ppyfkXF....

This is what I figured out so far, and I think the transistor could indeed be the problem, since it's not feeding audio out like the board I have that actually works. The green portion is where I got audio going into, I've been able to touch point and actually hear it, expected as this is the only p...

I'm a little lost with what to do next, but I'm probably gonna feed the outside board 5v and see if I can isolate it from within. As it stands I saw no shorts in the initial entry to the outside board, but again, my sight sucks, maybe something is in there, maybe I'm missing something. I'll post a m...

So it's replaced, still no audio. Wah wah wah.

Wow is the right one from a PAL NES ? (lol) I know the one on my NES look like the one on the left. No, all boards I have are NTSC. Most of my outside boxes are Mitsumi, this one is what looks like "Alps". It also has no bottom hole on the cover for the 5 pins going to the main board whic...

Hakko 808 comes with a big box of nope on the tweezers, though I have some. Maybe I could use nail clippers to brace it perhaps. The closeness of the work has me worried. I never intended on really doing SMD work because of how crap my eyesight is. I could, just go for it. This board is easier than ...
