Re: Monitor Audio BXW10

Hi all, I have BXW10 that powers up, red light on back but there is no operation .. I've taken the amp / psu board out and can see a small electrolytic cap with diode next to it and a small 4 pin device in front, the cap has some blackening along with the board which looks to have come from a failure of the 4 leg device .. does anyone have a circuit diagram or know what the device is? Should i replace the electrolytics, 4 leg devices diodes and the big smoothing caps and see what happens?
Anyone know what the voltages on the cable colours sulks be?...
