Hi all,   I have two Bs9000s (MK1/MK2) with power supplies (PCB3/PCB34) that I believe to be dead. No standby LED even after unplugging the other boards. I don’t have a ton of experience with component level testing and troubleshooting, so I’m looking for either someone who can point me to some things to look at, or someone who would be able to fix the boards if I send them to them. Happy to pay for the service if someone can do it. I am in the US so NA based would be best but can ship overseas if needed.   Thanks!
