Poor AC
connection
1. Check the air flow out of the cabinet by the fan.
(This does not mean that voltages or signals are as
they should be, but it does indicate that there is DC
power available from the Power Supply.)
2. Turn off power.
3. Remove line cord cable clamp.
4. Test line cord, power plug and I.E.C. connector for
breaks or damage.
5. Verify the continuity of each wire in cord.
