Power supply problems...

by futureanalogue on Thu Feb 21, 2013 5:12 pm

Hi there. got a new x0x (atomic mods) recently but having some power issues.... :evil: .I dont know much about how these work....

when i tried this with a 9v adapter it powered up but did not play the notes properly at all...after a while i got frustrated and turned the multi adapter up to 12v and it now works..????

Is this something to do with the psu i am using..? I just found out it is supposed to be 500mA but this one is 1200..!!!!

Also when i touch any switch it makes a horrible buzzing noise... :twisted:

Thanks in advance..Graham.

it smells like your adapter is DC-DC, which is wrong
the x0xb0x needs DC-AC (9V AC at around 300 to 500mA)

yeah i was guessin it was the psu...i got a proper 500ma adaptor and it worked fine for a while, but then i connected it to my pc to do an update(a should have bloody left it) this has now pretty much bricked it. :(

when i turn it on a couple of random leds light up and nothing works....!

Please help

hm.. what app did you use to upload the firmware?
did you try switching the x0x on/off while the FUNC knob points to "RANDOM" for example..?

try to flash it again then, the bootloader may still be alive

check for correct baudrate (in the app settings) and give it a few more tries
if it doesn't change.. then probably the bootloader is corrupted
