Common Faults & Maintenance
PRAM Battery Leaks
The Lithium PRAM battery in the 605 is very prone to leaking and should be removed.
Capacitors
The 605's logic board uses electrolytic capacitors that often fail and leak. I would highly, highly recommend replacing them. The power supply also often needs recapping.
