大家早安—大家好!
歡迎收看本日液晶電視維修分享,我是—『Kao atunLCD(高雄.阿唐液晶)』曾仔!
來看今天的液晶電視維修分享,主角是:JVC(傑偉世)型號:50V


這裡是它的內部電路分佈:




它是可以啟動的!這個是歸零後的數據(並非是送電無反應)!

只是……
啟動後,只有亮起背光,但是影像卻沒有顯現???正所謂:『黑亮屏』是也!


面板工作電壓DC12V,已經來到終端顯示電路PIN端!
莫非 ─ 是面板短路?

不急!各位還記得嘛?上回有處理過一台同型影像暗陳的實例嘛?
故障板還在,來將它們交叉測試一下!

看吧 ─
已經重現當時,那個實例的暗陳畫面!
這樣也就意謂著:並非面板有問題!

所以ㄋ…………
只好來終端顯示處理電路上挑『骨頭』了!
查檢、除錯、更替良品!



OK的!
經過對電路查檢、除錯、更替後,已經有了正常影像,收工熱機中…………



提供參考,請多指教!
