During my attempt to update the firmware on this old,but awesome receiver. I ended up bricking the darn thing.
Attempting to update the firmware I accidentally knock off the rs-232 cable during the update process and now receiver sticks to stand by mode. It won't turn on.
Tried every possible troubleshooting steps to recover it,but nothing works. On the Nad software upgrade procedures if you cancel and if update fails it says.
1. Turn off unit
2. Open top casing
3. Put jumpers on J2
4. Turn unit on and proceed with the update.
What is a J2? and what kind of Jumpers do I need? I don't even know where J2 is inside the receiver. I manage to open the top casing. I'm just all lost from there. If I go through NAD service they will charge me an arm and a leg.
