Hello,
My miniDSP 4x10HD was working fine using the newest firmware. Now I can't connect to it anymore. 😕
Only thing that works is bootloader mode and firmware update works OK.
I can select preset on the front panel, but no LED is on at source select.
Any advise on how to get my miniDSP back to life?

I had that happen after a windows upgrade and so I am using an older PC to talk to mine now. Not seen the issue with source select LED though. Just to confirm. Is the miniDSP still working as a DSP?
Thanks for fast response. I was using it on my PC. Than moved it to my stereo and tried to connect it via an old laptop on Windows 7.
This was not working, so moved back to PC (Win 10) and still not working.
Checked DSP outputs. Put some music on input and check all outputs, but they are all silent. Don't know if music should come out after a firmware update.

Have you tried the reset button on the back , I can email you older firmware versions if you like or the current one I'm using on win10

I tried the reset button. Also used it to update firmware multiple times. Via my PC and 2 different laptops. All the same. Can update firmware, but not connect 🙁
Can you send me the older firmware?
I'm afraid hardware is broken, but not so easy to debug. Especially since I can't find a schematic or service manual.

I will later today , have you talked to minidsp they seem to be helpful with their products , send me your email by pm
Thanks for the firmware versions. I upgraded to both versions, but no success.
I found out that the positive and negative voltage for opamps is missing. Checked the feedback pin of LM2586, but is also 0V.
Hope the transformer is not broken. Seems to be dedicated...

I have send them one yesterday. I just updated the ticket because I'm sure it is the power supply. +15V and -15V are missing. At some point they where back for a short time. Must be bad contact on the PCBA somewhere.
There is 5.7V on the on/off pin of the LM2586 disabling the power supply.
Anyone how knows why the power supply is disabled?

5.7 V should be on. Is the RemIn jumper in place as that disables this and provided it is there and there is 12V coming in then should power up.
5V and 3V3 are there. So 12V is OK. I don't know which one is the REMin jumper and what it should do.
+15V and -15V are missing. I think these is generated by a switch mode power supply controlled via LM2586. This chip can be disabled pulling pin 1 high, which is the case for some reason.

I checked the manual but could not find it. Only jumper settings for input sensitivity. Can you send me the link?
Can't find the document. Just this:
