Abstract
A device and method for detecting a short circuit in an electrical component during a start-up routine. In an embodiment, a device may have a problematic display having a short circuit that may result in damage to other components of the device if the device were allowed to fully startup during a normal start-up routine. Thus, power supplied to the panel may be initiated in stages so as to monitor any current that may be flowing through the panel, which in turn, may be indicative of a short circuit in the panel. If enough “leakage” current is detected through the panel during this staged startup routine, then a short-circuit detection circuit may interrupt the startup routine and lock out the operation of the device until the detected short circuit in the panel can be addressed.
