Is there a better scan of the SCM portion of the SM? I blow it up to 250% and I sort of infer which component is which by looking at the PCB and matching closely with the SCM - the lettering is blurred. IT seems the SM exists in many places on the web, but it appears to be the same scan. No chance someone has an original? Also, it appears the main board is at least dual planar, meaning each component has pads on BOTH sides. yikes, I gotta sharpen up one of my pencil tips.... -----Original Message----- From: Josh Malone <[email protected]> To: m100 <[email protected]> Sent: Fri, May 17, 2019 10:32 am Subject: Re: [M100] Have a question about my M100

Check out the M100 service manual (https://ftp.whtech.com/club100/doc/m100ServiceManual.pdf) for troubleshooting steps on the power supply.
