@kevin-kinchin would it be possible for me to get the service bulletin as well. I have an iDR48 that is not booting. ---

Hi Paul, I will try and attached it for you. The bulletin is a modification to stop the power supply in the mix rack from causing it to fail. If you have the mix rack boot failure message on your surface touchscreen then it most likely has failed already. I had to have new mother boards replaced in 3 of my stock. ---

To be clear, once this issue has occurred its too late, the DSP chips are fried they had 48V applied to them. You need to do this mod before it occurs not after. ---

I would be extremely happy if someone could send me the PDF as well. Mine has not failed yet, but I would like to do the modification. Thank you in advance to anyone that has it. ---

Hi! Can you please send me this PDF file. Maybe it will help me with my iDR48. I am having problems with the motherboard and my wizard sees a short circuit but cannot find the source. ---

@kevin-kinchin do you still have the bulletin that you could send? I have two mixracks that are still kicking and I’d love to keep them in good shape, and I can’t find the file hosted anywhere. [Previous page](https://forums.allen-heath.com/t/idr-48-boot-failure/8868.md?page=1)
