在無任何原理圖狀況下要對一塊比較陌生的電路板進行維修，以往的所謂“經驗”就難有作為，盡管硬件功底深厚的人對維修充滿信心，但如果方法不當，工作起來照樣事倍功半。那么，怎樣做才能提高維修效呢？根據我公司進口設備維修中心統計出來的資料，應遵循以下幾個步驟、按順序有條不紊的進行。
方法一：先看后量
使用工具：萬用表、放大鏡
當手拿一塊待修的電路板，良好的習慣首先是應對其進行目測，必要時還要借助放大鏡，看什么呢？
主要看：
1、是否有斷線；
2、分力元件如電阻、電解電容、電感、二極管、三極管等時候存在斷開現象；
3、電路板上的印制板連接線是否存在斷裂、粘連等；
4、是否有人修過？動過哪些元器件？是否存在虛焊、漏焊、插反等操作方面的失誤；
在確定了被修無上述狀況后，首先用萬用表測量電路板電源和地之間的阻值，通常電路板的阻值都在70-80？以上，若阻值太小，才幾個或十幾個歐姆，說明電路板上有元器件被擊穿或部分擊穿，就必須采取措施將被擊穿的元器件找出來。具體辦法是給被修板供電，用手去摸電路板上各器件的
溫度，燙手的講師重點懷疑對象。若阻值正常，用萬用表測量板上的阻、二極管、三極管、場效應管、撥段開關等分力元件，其目的就是首先要確保測量過的元件是正常的，我們的理由是，能用萬用表解決的問題，就不要把它復雜化。
