Safety Checks
Leakage Current
After re-assembly of the unit, always perform a leakage test on all exposed conductive parts such as metal connectors,
chassis, and mount.
With the unit powered, the following circuit should be connected from earth ground to each exposed conductive part on
the repaired unit. A DMM is placed in parallel with this circuit to measure AC rms or DC voltage. If leakage currents are
greater than the maximum allowed, inspect the TV for insulation or component breakdowns.
The maximum allowed leakage current depends on the type of power the unit receives and whether the unit is within
reach of the patient bed/chair.
