你部機其實唔難整... ic, mosfet , resistor 係咁多 -
- #14 [Cnn], 23-01-19 14:18多謝師兄相助, audiofan 兄, 可否提供R3511數值? 因圖看不到, 謝謝.
- #13 [daniel-chui], 23-01-19 12:06早兩個月前,修理一個Switching power supply,係一個Network Music Player (英國 Lxxn ),個design好離譜,果只schottky diode(輸出6V /3A)就咁SMD焊落去PCB,連散熱鋁片都唔安裝,利用PCB去散熱. D零件唔散熱,好快收工

- #8 [lnchu1], 23-01-19 11:24俾錢買本service manual 研究吓, 免費的也可能找到.
- #7 [olivea88], 23-01-19 11:19R3511 係咪燒左?
- #6 [olivea88], 23-01-19 11:15要度下 Q3501有冇 short 先?
- #5 [olivea88], 23-01-19 11:13一般用10 ohm 一定著番機... 數值對不對一回事...

最後修改時間: 2023-01-19 10:35:17 - #1 [Cnn], 23-01-19 10:33各位師兄,
有一天發覺開不著機, 打開機蓋,發現power board有粒電阻燒咗 ( 其他fuse 原好). 但看不到數值.在網上找Schematic diagram 一整天都找不到. 本機在港買但現在國外(不在港)
C hing 有何意見?
能否買到power board ?
謝謝各位.
