Reebok treadmill PSU SW01-CA-REV1.0 blown

[Sheppma]

Hi, I have a Reebok treadmill PSU SW01-CA-REV1.0 (KSW13) that's blown, I can identify most parts but have diode D7 and chip capacitor C8 that have burnt out and are unidentifiable - does anyone have a schematic or a PCB they can identify the parts from?

Re: Reebok treadmill PSU SW01-CA-REV1.0 blown

you need to remove the relays and the polyester and electrolytic cap and get rid of the rest of the carbon
also the cap may have leaked and caused the arc

the diode is probably just a regular rectifier like a UF4007 feeding power to the chip from the aux winding of the transformer

From the photo you can see that it costs SDH8303.
