style="font-size:12pt;font-family:宋体;">在检修<span lang="EN-US">STR6709的开关电源大家经常碰到电源不起振或主电压低等。在检修这种故障最重要分清故障的大概位置，把故障范围缩小，避免走弯路，从而提高维修速度，现跟大家共同探讨两种维修方法。<p></p></span></span></p><p class="MsoNormal" style="margin:0cm 0cm 0pt;text-indent:24pt;line-height:22pt;mso-line-height-rule:exactly;"><span style="font-size:12pt;font-family:宋体;">第一、在维修中经常发现开机电源指示灯闪一下，随后进入保护状态或主电压低的故障，在判断这种故障时一般考虑电压取样电路，当怀疑取样块<span lang="EN-US">IC603（SE110）损坏时，手头上没有此块代换时，可以用两个15K电阻代替IC603（SE110），两电阻串联两端分别为IC603的</span></span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">1</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">、</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">3</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">脚，中间端为IC603的</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">2</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">脚。测量＋B电压前把Q301激励管c、e极短路使行停振。＋B电压应该接近原＋B电压，此方法只能用来判断IC603的性能好坏，但不能使行振荡提供电压正常工作。<p></p></span></p><p class="MsoNormal" style="margin:0cm 0cm 0pt;text-indent:24pt;line-height:22pt;mso-line-height-rule:exactly;"><span style="font-size:12pt;font-family:宋体;">第二、电源不起振或灯闪检修：因为电源不起振包括有启动电路、振荡回路、正反馈，取样电路等都可能造成电源停振。在检修中要搞清电路的基本原理，用方法判定故障位置，缩小故障范围。大家都知道创维大屏幕彩电均采用<span lang="EN-US">STR为核心的开关电源。若待机、取样、低压输出级出现故障都会使光耦IC603（SE110）</span></span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">1</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">、</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">2</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">脚的电流发生变化直接反应给光耦内部的</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">3</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">、</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">4</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">脚光敏管内阻变化，使电源进入保护状态。根据电路原理用一个固定电阻代替光耦管内部的光敏电阻。强制电源振荡，不受取样电路或输出次级及待机控制电路的影响。具体的方法是：先把行激励管Q301c、e极短路及分别断开开关变压器T601各级低压绕组，然后取下光耦IC603，用一个2.7K电阻接原IC603的</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">3</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">、</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">4</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">脚上。如果电源启动，正反馈正常时，主电压应该有135V左右。反之即是电源初级电路有问题。采用此方法能很快的判断故障的大概位置。例：5T20开机指示灯闪一下进入保护状态。由故障来看可能出现在取样电路，更换IC602和IC603无效。于是用上述的方法检修，主电压有135V输出。这点可说明电源振荡初级基本正常，更确定了故障还是在取样电路部分，重换IC602故障排除。<p></p></span></p><p class="MsoNormal" style="margin:0cm 0cm 0pt;text-indent:24pt;line-height:22pt;mso-line-height-rule:exactly;"><span style="font-size:12pt;font-family:宋体;">小结：由于取样块失效，导致光耦内部光敏电阻变化使电源进入过压保护。由此故障看来很简单，但在代换新元件时也有可能性能不良的，若碰到这种情况时，常常会走弯路给检修带来很大的困难。用此方法也适用其它机芯，其电阻的大小通过计算得：先测量<span lang="EN-US">IC603的</span></span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">3</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">脚外接电阻R616（5T20机芯）两端电压U1，根据I1＝U1/R1得出电流值I1，然后测光耦IC603的</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">3</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">、</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">4</span><span lang="EN-US" style="font-size:12pt;font-family:宋体;">脚两端电压U2得R＝U2/I1所求电阻值，5P20、5Y221参考电阻值分别为10K和1K，大家有兴趣不防试一下。<span
