請問DPC-R7不讀碟的問題

darinl2009

手上有一台DPC-R7，想請問老師幾個問題
1.DPC-R7跟DPC-80是否為同一個型號，我是否可參照DPC-80的維修手冊
2.我手上的R7可通電，CD片會旋轉，幾秒後即停止旋轉，顯示屏顯示DISC，無法讀到碟。想請問會是電機，齒輪，光頭還是電容的問題呢?
3.若需更換光頭模組，請問要尋找哪個型號呢?
謝謝老師!

Sure, R7 is identical with DPC80. You can refer to DPC80's SM.
First step, you'll replace all onboard electrolytic caps, SMT or DIP, all of them; also clean leaking electrolyte from caps.
Second, test reading.
If reading fails again, replace the laser optical head. You can replace the original one by any of following: KSS165/167/220/221, they are compatible.
