BDP-LX55 and BDP-450 basically are using the same switching power supply. only minor different capacitors were applied on the secondary circuits.
the same psu board was applied in many Pioneer entry-level BDP's , besides 55 and 450 ! {:1_343:}

開關電源 紋波Peak to Peak voltage
當Full load 時，有一些尖峰出現
because the original BDP-450 psu has simple/poor emi filter circuit.

上下各三枚M4鑼絲分別牢牢結合中間金屬支架，左右各一粒，連埋原本的鑼絲也要裝上
超級穩固
再為機主安裝主開關掣.....
no LED power indicator as LX55 ?

謝謝Billy 提示安裝如LX55 的LED
拆開後，Power switch 已經有透明導光膠，謝天謝地
大佬、唔駛咁大手筆卦？
一條導線自 panel板 R629取 +v、一枚 mini-LED, 一粒smd電阻，一片smd電容，中! {:1_351:}
改完 standby mode = LED_Off,power on mode = LED_On.
