I have an IDR-48 connected to an i Live T112
It is coming up Mix rack boot failure
I have read that this is a common problem with the power supply on the DSP board
Does anyone have the information available to repair this
I think there was a service bulletin available a few years ago
Bump

Im in australia
too far from Germany
I am confident i can repair this if i have the service bulletin
Im sure someone has the info i need
Hi Juno53,
Have you been able to find the tech brief on the fix? We have the same problem but can’t find any info.
Is anyone able to supply a copy of the tech bulletin for this fix? Someone must have it? A&H?
Hi guys,
This has happened to three of my mixracks.
The service bulletin is how to modify the pcb and add a component but in your cases the DSP will be damaged and require a new motherboard. Basically the 48v and 5v tracks are extremely close to each other, and once dust has settled on this area and the unit is exposed to high humidity levels, moisture on the surface allows the 48v to leak across to the 5v rail over.I was told that this only happens in humid countries, but take a mixrack that’s been in a cold truck all night into a warm venue and see how much condensation appears on its surface. I have the recall bulletin if you still want it though.
Hi everyone, all that have a problem with the above problem ( DSP Boot failure ) had a solution that can share ?
Thank you in advance

No solution. Gave up and replaced with a Behringer Wing.
Hi all,
I try to get some broken mixrack (spare part and debuging)
If some of you are ok for give/sell to me let me inform please 
Do you have the recall bulletin on how to do the mod?
Hi, yes I have. I can’t see a way of attaching a pdf file to my message though, here on the forum, only pictures.
Hi, yes it is done, hope this helps with your problem 
Thanks
Any other critical service bulletins you have? Ill go thru out 8 iDRs and check for this, Id heard of it but never saw the doc and just had our first failure that appears related this week.
Haloo… Can you share original PDF, I can look the picture
