style="font-size:16px;">維修家用電器時(shí)判斷圖象彩色的標(biāo)準(zhǔn)是：a.彩色的濃度與色調(diào)要正常，b.無(wú)彩色不均勻現(xiàn)象，c.對(duì)屏幕**及邊緣均要求會(huì)聚良好，d.無(wú)爬行現(xiàn)象出現(xiàn)。彩色部分的故障一般發(fā)生在色通道電路，基色矩陣電路及顯象管電路。黑白圖象正常，檢查圖象彩色，在檢查圖象彩色時(shí)。應(yīng)將AFT開(kāi)關(guān)調(diào)至ON狀態(tài)，將色飽和度旋至彩色適中的位置。4、檢查伴音，由于電視機(jī)伴音的信號(hào)要經(jīng)過(guò)公共通道，由視頻檢波后產(chǎn)生第二伴音中頻信號(hào)，故伴音部分的檢修應(yīng)在圖象檢修完畢后進(jìn)行。需要說(shuō)明的是并不是每一臺(tái)電視機(jī)都要按照上述步驟進(jìn)行，對(duì)于某些明顯的故障，如無(wú)圖象，無(wú)伴音，爬行等故障范圍很清楚，就可省掉上述步驟，針對(duì)故障進(jìn)行檢修。直觀判斷法直觀判斷法是通過(guò)人的眼，耳，鼻，手感覺(jué)來(lái)感知機(jī)器部件的形，色，音，味，溫的變化情況來(lái)判斷故障的性質(zhì)及損壞情況。</span> </p><p> <span style="font-size:16px;">電源是機(jī)器的心臟，如果電源不正常，就不可能保證其他部分的正常工作，也就無(wú)從檢查別的故障。根據(jù)經(jīng)驗(yàn)，電源部分的故障率在整機(jī)中占的比例較高，許多故障往往就是由電源引起的，所以先檢修電源常能收到事半功倍的效果。對(duì)污染較重的電氣設(shè)備，先對(duì)其按鈕、接線點(diǎn)、接觸點(diǎn)進(jìn)行清潔，檢查外部控制鍵是否失靈。許多故障都是由臟污及導(dǎo)電塵塊引起的，一經(jīng)清潔故障往往會(huì)排除。低壓部分(毛細(xì)管---蒸發(fā)器----回氣管.)一般漏點(diǎn)在銅鋁接頭地方.也有在鋁管砂眼地方.下面說(shuō)開(kāi)后背程序及銅鋁管怎樣焊接。其實(shí)，日常生活中見(jiàn)到的各種各樣的物品都是有使用期限的，但家電的使用期限很容易被大家忽略，很多人都是等用壞了才換，殊不知這樣存在這巨大的安全隱患。因此，只有合理的使用和維修才能讓家電使用更長(zhǎng)久！</span>
