Re: Tektronix TDS1002 w/ Ault SW424RA0000F03

I know this is a very old topic, but I need to share!

I came here looking for a solution to this power supply fault; however, I've discovered that C6 caused the fault in my case. This 56 uF bad cap caused the failure.

I have the same oscilloscope model with the same power supply brand but a different part number (PN: SW424KA0000F02). Upon connecting the power cord and switching it on, nothing occurred. After removing the power supply board and measuring the J9 voltage outputs, they're all 0V.
