師兄我係Manual睇到段野,可以用來試下個十仔work吾work.

"5. If the Power LED is lit, but you still hear no sound, try this test: Disconnect the phono
interconnect cable from the back of the receiver or processor. Touch the tip of the connector. If
you hear sound coming from the subwoofer when you touch the connector, the subwoofer is
working. You need to look elsewhere in your system to solve the problem."

今次記得先關曬D電先好拔插......

    師兄再 close-up 果part 睇睇。。。。
好似"燒＂得好勁喎！.....不過、好奇怪點解 diode 個位都會燒到無剩！...doubt,doubt,doubt....
一撻撻穢漬，感覺係附近爆電容引致的破壞。你未拆底板時，呢part 鄰近咩嘢呀？

U9 係咩編號I.C.?

    upload左全相比你睇..壞左個個位後邊係訊號線L&R位....因為我用aq sub-3尋晚裝完插左落R..我睇番post D C兄叫我插番落L之後我直接插就出事-_-

點解塊電源版好似好流?話哂都美國野..就算係大陸做都唔會差成咁?
