style="font-size:16px;">以常見的空調為例，中長期來看與日本家庭相比，中國農村和城鎮(zhèn)的每百戶空調保有量分別只相當于日本1993年和1982年的保有量水平，假設城鎮(zhèn)空調每百戶保有量對標日本、農村空調保有量對標當前城鎮(zhèn)，中長期看我國城鎮(zhèn)和農村空調保有量分別具有105%、118%的提升空間，仍然有近乎翻倍的增長空間。由此帶來的空調維修市場，也擁有市場規(guī)模翻倍的發(fā)展空間，市場遠未飽和。與空調類似，洗衣機、冰箱、油煙機等主要家電，農村的百戶保有量差不多約為城鎮(zhèn)百戶保有量的三分之一，而城鎮(zhèn)百戶保有量對比發(fā)達國家仍有不小差距，行業(yè)整體存在巨大的增長空間。服務專業(yè)度提升：隨著智能家電的發(fā)展,像GBA芯片、編程器和修屏機也加入了家電維修業(yè),一把烙鐵一只萬用表的維修已經(jīng)遠遠落后這個時代了，這就對家電服務機構的專</span><span

style="font-size:16px;">檢修電視機內部電路時，必須把電視機和外部電源斷開，把測試儀器指針（如示波器指針或萬用表表針）的接地線與電視機的地線接好，然后通電，再用“高電位”探針測試，這樣可預防短路和觸電。4、要裝卸，挪動或處理顯象管時必須戴上不碎玻璃做的護目鏡，不戴護目鏡的人員不要接近顯象管。處理顯象管期間人體盡量離顯象管遠些，因為顯象管是有性的器件，裝卸，挪動或處理時都應該特別小心。當需要把顯象管從機殼內拿出時，應該先切斷電源，拔除高壓帽及顯象管座，再用螺絲刀將顯象管高壓對外面的導電敷層進行放電之后，用粘接帶（比較好是綁帶型，帶寬19MM左右）卷繞顯象管頸部，以便固定偏轉線圈，然后用一只手托住熒光屏，慢慢的取出。當把電視機底板（印刷電路板）**檢查各點電壓時，應把印刷電路板用絕緣材料托起。以防與維修臺上的東西接觸發(fā)生短路。6、不可以隨意用大容量保險絲代換小容量保險絲，在查明故障原因之前，不可隨意更換保險絲，以免故障擴大損壞其他元件。</span> </p><p> <span style="font-size:16px;">家用電器維修就找精城家電直觀法檢修時，主要分成以下三個步驟：（1）打開機殼之前的檢查：觀察電器的外表，看有無碰傷痕跡，機器上的按鍵、插口、電器設備的連線有元損壞等。（2）打開機殼后的檢查：觀察線路板及機內各種裝置，看保險絲是否熔斷；元器件有無相碰、斷線；電阻有無燒焦、變色；電解電容器有無漏液、裂脹及變形；印刷電路板上的銅箔和焊點是否良好，有無已被他人修整、焊接的痕跡等，在機內觀察時，可用手撥動一些元器件、零部件，以便直觀法充分檢查。（3）通電后的檢查：這時眼要看電器內部有無打火、冒煙現(xiàn)象；耳要聽電器內部有無異常聲音；鼻要聞電器內部有無煉焦味；手要摸一些管子、集成電路等是否燙手，如有異常發(fā)熱現(xiàn)象，應立即關機。</span>

style="font-size:16px;">油煙機影響炊事火源熱量排風量選擇過大，引起熱量浪費，延長了加熱時間，要適當選擇排風量;抽油煙機安裝過低，應適當提高抽油煙機的高度。油煙機臟污嚴重沒及時清洗抽油煙機，應及時清洗擦試抽油煙機;未對風道清洗，可斷電后，打開蓋，取出各檔板和濾網(wǎng)，清洗干凈后裝好。電源沒有電，待電壓正常后即可；內部線路接錯，按線路原理圖重新接線；開關故障，更換開關；主控板故障，更換主控板（如保險絲或變壓器壞等）（對采用電子或觸摸屏開關）；冬天戴手套按電容感應式開關沒有反應屬正?，F(xiàn)象，摘下手套重新試試；對于有接線柱的吸油煙機，如果接線柱上線路沒有上好，如固定線路的螺釘壓到外面的膠皮上；保險管燒斷或接觸不良；對于插件接線的油煙機，由于長途運輸可能會有插件脫落現(xiàn)象，檢查修復；電源線短</span><span

style="font-size:16px;">加溫的順序是先晶體管，集成電路，后電容，電阻。通常加溫有兩種含義，一是加速元件的損壞，使故障盡快出現(xiàn)。其二是由于機板受潮，利用加熱的辦法直接排除故障。與加溫法相反的方法是降溫法，這種方法通常和加溫法聯(lián)合使用。其簡單的方法是在機器出現(xiàn)故障時用棉花蘸上酒精貼在懷疑的元件上，讓其冷卻，如果冷卻到某個元件時故障消失，則這個元件就是壞元件。降溫法特別實用于剛開機時正常，用一段時間后出現(xiàn)故障的機器。在線測試法在線測試不但可以進行電流，電阻的性能鑒別，而且還可以測試二極管，晶體管及電感，電容等元器件的電參數(shù)。另外還可以很快測出印制電路中的電流分布等一些難以用傳統(tǒng)方法測試的項目。例如，測量在線電阻值，在線電流值和在線二極管，晶體管的各項參數(shù)。（8）調整法家用電器的故障中很大部分是使用不當引起的，其中有一部分是由于不正確的調整引起的。這里主要討論的是引起故障的幾種需要注意的調整內容和方法。調整分為：會聚調整，白平衡調整，色純度調整，頻率調整，偏置調整，相位調整，時間調整，網(wǎng)絡調整。</span>
