Hi to everyone!
A few years ago i bought a x0x kit from willzyx site.
That x0x never worked and willzyx never answered my mails. (Thanks willzyx!)
The leds fires up but i never had ANY kind of audio coming out from it.
I’m a professional hw tech, i have all kind of equipment (oscilloscope, professional soldering station etc.)
Please, can someone help me guys to troubleshoot that x0x?
Thanks

Re: x0x no sound
I'm assuming you already checked the power supply voltages?
The first thing I'd probably check is if the oscillator is running. Probe the contacts of the waveform switch with the oscilloscope (AC coupled; the waveform is normally riding on a large DC offset).

Hi mmm!
Thanks for the answer…I’ve read a lot of your answers in this forum.
If i remember correctly all the voltages was perfectly fine and all the other things you asked me to check was also perfectly fine but i will check them again asap…
I will check everything again and,
no joke, i will pay you if you help me to make that x0x able to sound
Message to everyone: don’t buy from willzyx.

Re: x0x no sound
That looks to me as if the oscilloscope probe isn't grounded.

Hi
I’ve checked that again with the same results, with different ground points

Re: x0x no sound
Sorry to bother…but i really badly want to make that x0x sounding…nobody has ideas to check where is the problem?
I can pay in advance if someone can help me…

Re: x0x no sound
If you're in Europe it's trivial: send it to me. I have yet to see a Xoxbox that couldn't be fixed and I have worked on probably over 100 so far.
If you're outside Europe we can do this right here in the forum - but you would have to follow exactly the procedures I'm proposing.

Re: x0x no sound
I live in Europe (Italy), but actually i would prefer to fix it by myself (following exactly your instructions obviously!)
Thanks

Re: x0x no sound
OK.
I'd like to see a few pictures, both of the mainboard and the IOboard. High resolution would be nice; and of course both sides of the PCB.

Re: x0x no sound
Yes, that looks good so far. I wanted to get an impression of the general build quality; I'll also look into possible problems on the pics. And then we'll start the whole troubleshooting process.

Re: x0x no sound
Thanks, really appreciate that!
Also: I can’t find why some x0x are called banned…I’ve tried to find info about that with no luck!
