skweeegor Posted October 17, 2020 Report Share Posted October 17, 2020 (edited) Hello, My sammichSID has been sitting in a box for while, and was previously working. I just took it out to hook it up, and it wouldn't turn on :( I started doing voltage tests, and 9V/12V are all good on the bottom PCB, but there is an issue with 5V. I read 5V at the voltage regulator (labeled 1 in the bottom right of my picture), so that is good, but at the 5V pad of J2, I only read 0.02V. So the problem seems to be near the voltage regulator. I also only read 0.02V at all other 5V test points in the build guide. Am I correct in thinking that I should also read 5V at C3 (labelled 2 in my picture)? If so, I only read a few mV there, which makes me think maybe the capacitor is the issue. But I'm not too knowledgeable in circuit theory so I'm not sure. Would appreciate any help! Thanks Edited October 17, 2020 by skweeegor typos Quote Link to comment Share on other sites More sharing options...
