              LED顯示屏故障維修處理

              文字:[大][中][小] 手機頁面二維碼 2018/5/3     瀏覽次數:    
                一、led顯示屏剛上電時出現幾秒鐘的亮線或屏幕畫面變花的原因?
                將屏幕控制器與電腦及HUB分配板和屏幕連接妥當后,需要給控制器提供十5V電源以使其正常工作(此時,切勿直接與220,'申壓相連接)。上電瞬間,屏幕上會出現幾秒鐘的亮線或“花屏”,該亮線或“花屏”均是正常測試的現象,提醒用戶屏幕即將開始正常工作。2秒鐘內,該現象自動消除,屏幕進入正常工作狀態。

                二、載入不上或通訊不上的原因是什么?
                通訊不上與載入不上的原因大致相同,可能是由于以下幾種原因造成的,請根據所列各項與操作進行對照 。
                1、確??刂葡到y硬體已正確上電。(十5V)
                2、檢查并確認用于連接控制器的串口線為直通線,而非交叉線。
                3、檢查并確認該串口連接線憲好無損并且兩端沒有松動或脫落現象。
                4、對照led顯示屏控制軟體和自己選用的控制卡來選擇正確的產品型號、正確的傳輸方式、正確的串口號、正確的串列傳輸速率并對照軟體內提供的撥碼開關圖正確地設置控制系統硬體上的位址位元及串列傳輸速率。
                5、查看跳線帽是否松動或脫落;如果跳線帽沒有松動現象,請確保跳線帽的方向正確。
                6、如經過以上檢查并校正后仍然出現載入不上,請用萬用表測量一下,是否所連接的電腦或控制系統硬體的串口被損壞、以確認是否應送還電腦廠家或將控制系統硬體送還檢測。

                三、自動或手動亮度調節是什么意思?
                亮度調節是指在屏幕所能顯示的最暗與最亮之間所做出的調整,而非感光調節。自動亮度調節是根據不同的時間段所應出現的不同亮度而由詣闊LED屏幕控制系統自動調整至某一預定亮度。手動亮度調節是指終端用戶透過對LED屏幕控制系統的操作,讓LED屏幕達到某一指定亮度。

                四、LED屏幕出現屏幕全黑的原因是什么?
                在控制系統運用的過程中,我們偶爾也會遇到LED屏幕出現屏幕全黑的現象。同樣的一種現象可能是由各種不同的原因導致的,就連屏幕變黑的過程也會因不同操作或因不同環境而異。比如它可能是一上電的瞬間就是黑的,也可能在載入過程中變黑,還可能是在發送完畢后變黑等等:
                1,請確保包括控制系統在內的所有硬體已全部正確上電。(+5V,勿接反、接錯)
                2、檢查并再三確認用于連接控制器的串口線是否有松動或脫落現象。(如果在載入過程中變黑,很可能是因為該原因造成,即在通訊過程中由于通訊線松動而中斷,故而屏幕變黑、千萬不要以為屏幕體沒有動,線就不可能松動,請動手檢查一下,這對想要快速解訣問題很重要。)
                3,檢查并確認連接LED屏幕及與主控制卡相連的HUB分配板的是否緊密連摻、是否插反。

                五、單元板出現整片屏幕不亮、暗亮的原因
                1、目測電源連接線、單元板之間的26P排線及電源模組指示燈是否正常。
                2、用萬用表測量單元板有無正常電壓,再測量電源模組電壓輸出是否正常,如否,則判斷為電源模組壞。
                3、測量電源模組電壓低,調節微調(電源模組靠近指示燈處的微調)使電壓達到標準。
