iMac (17-inch Mid 2006/Late 2006 CD) Take Apart — General Information 
Safety
Warning: When the iMac is under power, be aware that the power supply contains high voltages 
that pose a potential hazard to your personal safety. Never work on or near the power supply 
with the unit powered on, and as a further precaution always make sure the unit is unplugged 
when working on it with the front bezel removed.
WARNING: HIGH VOLTAGE 
Text or photographs marked by this symbol indicate that a potential hazard to your personal 
safety exists from a high voltage source.
The power supply board is a high voltage source with the unit under power, and remains 
powered up whenever the system is plugged in, whether or not the system is turned on. Use 
extreme caution when troubleshooting the system with the front bezel removed.
Disconnect power to the system before performing maintenance.
Don’t work alone. In the event of an electrical shock it is important to have another 
individual present who can provide assistance.
Keep one hand in your pocket when working on any iMac that is plugged in. This will 
help ensure that your body does not provide a path to ground in the event that you 
accidentally make contact with the line voltage.
Don’t wear jewelry, watches, necklaces, or other metallic articles that could present a risk 
if they accidentally make contact with the power supply circuitry.
