Hi all, sorry to resurrect this post, new member here looking for info to troubleshoot a dead V3/Classic.
Can someone repost or tell me what picture is referred to in mfieger's post regarding test point locations? I was able to find an updated link to the webpage that was referred to for the schematic but didn't see any photos there that seem to show the test points. Specifically, I don't see "large capacitors" or a "ceramic cap" on the PCB for the 5V and 14.8V. ------------------------------------------------------------------------ charliemcd's Profile: http://forums.slimdevices.com/member.php?userid=68552 View this thread: http://forums.slimdevices.com/showthread.php?t=74844 _______________________________________________ diy mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/diy
