The midi cable, or the audio device itself?

Hi. I'm looking for the schematic and/or pcb layout for the actual audio circuit board. It is a SB0300 Audigy 2NX. I LOVE this audio device because it totally eliminates all ground loops and hum. It will not power up. The power supply is OK. So, something has gone bad on the circuit board. Next to impossible to troubleshoot without a schematic. Hope someone can help. This product has been discontinued for some time now. Probably over 9 months.

Do you know what a capacitor is?

I am an electronic technician. I know what ALL components are. So, yes. A schematic is useless unless a technician is using it. You know of defective capacitors in this unit maybe?

Thats what I was going to suggest. Check for bad caps. If the top of one or more of the capacitors looks as if it were popped up then the capacitor is bad. You would have two options.

A - Throw the card out.
B - Replace the capacitor.

Let me know if this is the issue.

Need-a-Clue,

You have not responded. Is my answer still eligible for points?

Hello MOnitOr,

To be perfectly honest I did not know if you were joking with me or not. I mentioned that I am an Electronic Technician. Checking for shorted capacitors and capacitors that had been overheated and as such caused the expansion scores of the electrolytic to expand  would have been among the first few steps taken when checking the pcb for obvious defects. I have NEVER been stingy with points but your suggestion is one that you should have realized would have already been taken by me. If you will notice I did NOT ask for troubleshooting information OR for technical assistance. I ONLY wanted a source for a schematic. You were not answering the question that I posed. So, I do not feel that you are eligible for points. Do you???? I will now withdraw this question due to lack of appropriate response.

You said yourself, "You know of defective capacitors in this unit maybe?" You were asking me other questions irrelevant to the first one.

Often manufacturers WILL know of a problem component that fails often. I thought you might have known of such an item. I'm not here to argue. I just was looking for a schematic. Simple.
