Newly soldered EZ-20 audio -- a LOT of static and some wierd noises

http://www.youtube.com/watch?v=2h3OuFoQMks



I replaced a broken monitor with this one, which fixed the problems with the picture, however, now I'm getting a lot of static and some weird "woob-woob-woob" noises from the speakers :confused:

(You can hear the weird noises at about 13 seconds)

Any ideas?
 
When you capped the audio board, did you replace everything that came with the kit? I had an audio issue with my DK because I replaced everything except TR373 and TR374. I originally didn't replace mine because I couldn't figure out how to unscrew them from the heat sinks since the spacing between the two was so narrow. I just ended up desoldering one of the heat sinks so I could unscrew them.

I didnt buy a kit, I had one monitor that had good audio but needed replacement caps, and so I swapped that out with a working monitor.

I did, however, take the audio (plug thing?) ---the red and white cables-- from the old one and soldered it to the contacts on the new one. These are the cables that come together into a male unit that plugs into a female unit that is attached to the speaker.


^^ you can see them snaking into the cabinet at about second 12
 
If you had good audio on one monitor, but a bad pic, and a good pic on the other but bad audio, just move the sound board from the good audio one to the good pic one...
 
I think the volume is way too high.
When you coined it up that was way loud.
Try turning it down and see if the back ground noise goes away.

Did you route the cable the same way it was done in the old one? If you ran the speaker wires differently, that could make it pick up noise that it used to reject.

This. I can't see the video at work but when the volume is cranked on my Dk and DKJR I hear a lot of BS background noise. But turning it down to a reasonable level leaves the game play sounds intact and all the extras disappear.

I urned the volume down and it still was there :(

Im not really sure what is going on, ill try to get a closer up video of the parts in a bit....all I did was take of the red and white audio cables and solder them to the matching part on the mew monitor :confused:
 
Ok so I swapped the audio boards and the wierd noise still remains.

I'm thinking that there may be a problem with the wires I soldered....though I dont know why. Here are some pictures:
