<div style="color: rgb(0, 0, 0); font-family: Arial; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">這是我對本螢幕的故障描述：

<div style="color: rgb(0, 0, 0); font-family: Arial; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">機器啟動後一閃即滅！指示燈號也一同熄滅，單看文字描述，它的狀況就很糟糕！

<div data-original-attrs="{"style":""}" style="color: rgb(0, 0, 0); font-family: Arial; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">來拆機查檢了：

<div style="color: rgb(0, 0, 0); font-family: Arial; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">在這兩塊重要電路（電供、AD BOAD）上

<span style="-webkit-text-stroke-width:0px; color:rgb(0, 0, 0); display:inline !important; float:none; font-family:arial; font-size:medium; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; orphans:2; text-align:left; text-decoration-color:initial; text-decoration-style:initial; text-decoration-thickness:initial; text-indent:0px; text-transform:none; white-space:normal; widows:2; word-spacing:0px">我立即在主機板（AD BOAD）上，發現許多異狀，我都一一的指引給大家瞧瞧：

<div data-original-attrs="{"style":""}" style="color: rgb(0, 0, 0); font-family: Arial; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">AD BOAD整個清理過後，看起來又是一塊新穎的主板了，板上的濾波也一併全數更新。

<span style="-webkit-text-stroke-width:0px; color:rgb(0, 0, 0); display:inline !important; float:none; font-family:arial; font-size:medium; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; orphans:2; text-align:left; text-decoration-color:initial; text-decoration-style:initial; text-decoration-thickness:initial; text-indent:0px; text-transform:none; white-space:normal; widows:2; word-spacing:0px">我又在電供上發現料件導腳鏽蝕：

<span style="-webkit-text-stroke-width:0px; color:rgb(0, 0, 0); display:inline !important; float:none; font-family:arial; font-size:medium; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; orphans:2; text-align:left; text-decoration-color:initial; text-decoration-style:initial; text-decoration-thickness:initial; text-indent:0px; text-transform:none; white-space:normal; widows:2; word-spacing:0px">更新後的測試，終端電壓輸出不穩定，DC5V一直漂浮中：

電供終端輸出，一直出現異常，我正在苦腦中：

還對底層面板加強了清潔：

這裡是最終的燈泡負載實測：

OK！它總算立正站好，正在熱機（燒機）中。
