Safety
WARNING: HIGH VOLTAGE: The LED Cinema Display (24-inch) contains an AC/DC power
supply and logic board that pose a shock hazard. When the unit is under power, be aware
that the power supply and logic board contain high voltages that pose a potential hazard
to your personal safety. Never work on or near the power supply or logic board with the
unit powered on; and as a further precaution, always make sure the unit is unplugged when
working on it with the glass panel and LCD removed. A white, shock-hazard warning symbol is
silk-screened in the middle of the power supply module.
The AC/DC 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 glass panel and LCD panel
removed.
Disconnect power to the system before performing any repairs.•
Disconnect ESD wrist straps when working on a plugged-in unit.•
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 unit 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, or other metallic articles that could present a risk if they •
accidentally make contact with the power supply circuitry.
