XG-V10XUTROUBLE SHOOTING T ABLE (Continued)No audio outputAre there audio signal inputs at pins(2) and (23) of IC301?NoYesCheck the input, the switching circuitof IC403 and IC404, and theirperipheral circuit.Are there audio signal outputs at pins(3) and (6) of IC302?NoYesCheck IC302 and its peripheralcircuits.If the voltage at pin (7) of IC302 is notas specified, check Q302, Q303 andtheir peripheral circuits.Check IC302 and its peripheralcircuits, and the SP connectors andspeakers.Checkig the Power UnitThere is no voltage output atEA connector.NoIs EA connector disconnectedor loose?YesNoReconnect the EA connector.Is AC voltage (85-264V)applied across the BAconnector?NoYesReplace F1701.Is R727 broken?NoYesReplace R727 or Q701.There is a short-circuit alongthe EA output line. Using atester, check the resistancebetween each voltage line andthe ground.46
