PX - 2 TROUBLE SHOOTING If your PX-2 ceases to function normally, check the following trouble shooting list. Only if this fails to restore normal operation should you contact your local YAMAHA dealer or service representative,. Fault Power does not turn on when POWER switch is depressed. Balance (zero) cannot be obtained after changing cartridge. REPEAT play cannot be effected. No sound is heard, or sound is too faint although the stylus descends on the disc surface. The body of the cartridge catches on the disc surface. Unpleasant, distorted reproduced sound, with clicking or crackling sounds. High frequency reproduction is par ticularly affected. Unpleasant reproduced sounds with howling (droning) noise. Inclusion of humming noise during disc play. Cause Power cord not completely inserted into wall AC outlet, or amplifier's spare power supply socket. Cartridge is either too heavy, or too light. PLAY has been started manually. Has been manually operated during AUTO-PLAY. Defective contact of head shell connector. Amplifier's FUNCTION switch is not positioned to PHONO. Amplifier's volume is turned down. Insufficient contact of turntable output cord. Too heavy cartridge stylus tracking force. Inadequate tonearm height. Turntable is slanted and not properly leveled. Dust accumulating on the stylus tip. Stylus tip is worn down. The disc itself is damaged or is dirty. Stylus tracking force is either too light or too heavy. Amplifier's treble response has been overemphasized. Turntable is installed too close to the speaker system, or resonance has been induced by vibrations because placement of turntable is unstable. Ground wire of turntable not connected to amplifier's GND terminal. Defective contact of head shell connector. Cure Re-insert cord into wall AC outlet, or amplifier's spare power supply socket. The PX-2 handles cartridges in the weight range of 5g -- 11g: the sub-weights are not needed. When a cartridge of over 11g is to be used, fit on the sub-weights and perform readjustment. First depress PLAY/DISC SIZE button and then depress REPEAT button. Attach head shell to the tonearm properly. Set FUNCTION properly to PHONO. Turn up the volume to an adequate level. Check and correct connector terminals between amplifier and rear panel. Readjust tracking force to optimum. Adjust to proper tonearm height. Correct by leveling turntable properly. Clean stylus tip using special stylus cleaning brush. Replace the stylus. Replace with a new disc. Readjust the tracking force for the cartridge to the recommended value. Turn the treble control back to the flat position. Move turntable to a stabler place, or install it farther away from the speaker. (Installation in a corner of a room should be avoided in particular.) Connect ground wire to GND terminal. (In some cases, it is better not to ground it.) Fit the head shell onto the tonearm correctly. 12
