23、IER FAILURE DIAGNOSIS FLOW CHART For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of solderi

24、ng. Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC bo

25、ard on which reworking is required and the weight of the tip of the soldering iron.Do NOT use a soldering iron whose tip temperature cannot be controlled.Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to mel

26、t/easy to harden).The following lead-free solders are available as service parts: Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.Amplifier failure diagnosis flow chartWhen DC detection is activated (AMP_ERR flashes on the display), failure (damage) of t

27、he power amplifier section is considered.Caution:When releasing the lock state of power key before repair, please be careful because there is the possibility that more damages will occur when turning on the power once again! According to a symptom, perform the following confirmation beforehand.1) Ar

28、e there any Fuses and IC protectors open? 2) After turn on the power, confirm that the supply voltage of the point that can be measured is appropriate. (Particularly the supply voltage of the power Tr and drive step) 3) Whether the voltage of pin2 and pin5 of IC601 or IC603 is equal to (VL-0.7V). If

29、 not (eg, equal to VH), then change the corresponding power pack IC601 or IC603. 4) Furthermore, check the output DC voltage of each channel of power pack IC601 and IC603 to limit the failure channel and identify the defect power pack. After identify the failure channel, check that each part is not
