Need A4000 Motherboard

[amigamad]

A4000 motherboard back from repair to fix the mangled sound, and it is STILL completely screwed

If thats the case send it back and tell them you want it fixed seeing as thats what they were paid to do. :-?

hi NightShade737

what make you think, that it is the capacitor/s the cause?

At this point, try yourself to replace it.

You can use even a not SMD one.

Please read the rest of the thread.

General census from experienced people.

Replace what? I have just had all the 22uF caps replaced, doing it again would be pointless.

This is rather odd. Playing music with EaglePlayer works fine, which is really quite strange as it must use some sort of manually created channels for the sound. (don't say I must now have a software problem because the problem is always there other than that point, even on self booting games).

Maybe the distortion is less noticable with Eagleplayer as maybe it's only using one channel?
Or perhaps the audio from Eagleplayer is at a low enough level so that if the op-amp bias voltage has been offset, the amplifier's output is not noticably clipping?

Anyhow, if you want to replace the board, that's fair enough.
Interested in selling your old one for a reasnoble price?  I could do with a few more spares for swapout repair jobs.

Sorry, I'm doing an (almost) stright swap with someone else, but thanks for the offer.

The tracks with Eagle are the same songs, at the same volume, which is why it is wierd...
