So I bought an MV1FZS from ol Bill Burgerbutt recently. He said it had no video. It was $40 so I figured what the hey, maybe I can learn a thing or two about fixin' Neos. I got it today and it does indeed have video.
But it has no sound. Here's what I know so far:
The volume pot will make a difference in what I 'hear'. Its just your standard speaker hiss, but it WILL change the volume if the pot is turned up or down.
Tried a JPN BIOS, as well as an older UniBIOS I have layin around (still got my old purchased one from Raz ) and they did not make a difference. I dunno if that was to be expected, but it wouldn't hurt to try, right?
Going into the hardware test menu via dip switches, I was able to test the speakers, and I successfully heard the little "ooo" tone from the left, right and stereo selections. Doesn't that right there tell us that the board has working sound?
A cursory examination of the board shows that it's pretty damn clean for being ancient, and it doesn't look like any parts are broken. I tried it with an actual Neo cart, as well as the other Banana cart I have, and still nuffin.
Any ideas as to what might be the cause of this?
