A4 MKII "d error"

hey there,
i’ve been using my A4 MKII for almost a year.
Now it doesn’t start anymore. Black display…
So i’ve tried to switch the PSU’s. A4 mk2>rytm mk2. it boots again.

Test mode MSG:

——————
d ERROR

UI:(+)
DRAM:(+)
FPGA:(+)
AUDIO:(+)
UI FIRMWARE: 1.2
OS: 1.40

——————

The Rytm doesn’t boot with the A4 PSU.
All the Knobs and trigs keep flashing. No boot. Black display
Do i have to worry about the ‚d ERROR‘ ?
did someone else experienced something like this?
Hardware issue? PSU issue? What do you think?

I don’t think so, I have seen this reported and have this myself

Sounds like your PSU barrel connector may be broken, or the PSU is broken
