I have a CCR1036 r1 and its health is showing 23.3v right now and it is making me very nervous....Got a CCR1009 here with these symptoms (temperature reboot, though unit is cold). Replaced bulged caps C1442 and C1443 (680µF/10V) with Panasonic FR and it worked again. System Health showed voltage around 22V. This seemed a bit low.
Looks like the power supply caps gave up first and then the high ripple eventually killed the caps inside the router. Lesson learned: Watch the voltage display and if it drops below 24V, replace the power supply before it causes further damage. Replacing the caps inside the router was no fun. You have to remove the CPU heatsink (heat pipe) and soldering this multilayer PCB requires a LOT of power.
It requires a flight to get to and my network relies on it..
So very nervous..
