Re: 2nd QMX Build and it wont power on and an update on my old unit...


 

Hans,?

The sweeps were terrible. And I have no audio out of the 1st QMX. I worked with John Zbrozek a good bit with the 1st unit and we got it that far and we decided that the PCM1804 was likely bad. I went looking for a replacement and found several models on digikey or Newark (one of the two) but was unsure which to purchase. No you hadn’t missed replying before… I did however try to send you a private message on here a while back and I’m not sure if it ever even went…?


Cliff,

I did try swapping power boards from the old unit one at a time to the new. My old 5v board and my new 3v board allowed me to get the unit powered up to apply firmware, but now it will not power up again. Swapping the power boards every which way gives me no change now. And putting the old boards back into the old QMX sends it back to the way it was this morning when started…. I’m pretty confused haha.

Thanks,
