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(jī)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(jī)器出現(xiàn)故障時(shí)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(gè)元件時(shí)故障消失，則這個(gè)元件就是壞元件。降溫法特別實(shí)用于剛開機(jī)時(shí)正常，用一段時(shí)間后出現(xiàn)故障的機(jī)器。在線測(cè)試法在線測(cè)試不但可以進(jìn)行電流，電阻的性能鑒別，而且還可以測(cè)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(cè)出印制電路中的電流分布等一些難以用傳統(tǒng)方法測(cè)試的項(xiàng)目。例如，測(cè)量在線電阻值，在線電流值和在線二極管，晶體管的各項(xiàng)參數(shù)。（8）調(diào)整法家用電器的故障中很大部分是使用不當(dāng)引起的，其中有一部分是由于不正確的調(diào)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(diào)整內(nèi)容和方法。調(diào)整分為：會(huì)聚調(diào)整，白平衡調(diào)整，色純度調(diào)整，頻率調(diào)整，偏置調(diào)整，相位調(diào)整，時(shí)間調(diào)整，網(wǎng)絡(luò)調(diào)整。</span>
