Probably caps but a lot of power supplies have a sense circuit that won\u2019t come up if it doesn\u2019t sense a 5V load on it. Thats a place to start looking if you have the schematics. If your not a purest that would be a pretty easy machine to put a 1u tax supply into. I did that with one of my IPX machines and it works great now.</div><div dir="ltr"><br></div><div dir="ltr">-t</div><div dir="ltr"><br></div><div dir="ltr"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div style="font-size:medium;margin-top:0px"><div style="margin-top:0px;font-weight:bold"><div style="margin-top:0px"><div style="margin-top:0px"><div style="margin-top:0px"><font style="font-size:14px">Todd Vernon</font></div><div style="font-weight:normal;margin-top:0px"><font style="font-size:13px">Entrepreneur | Investor</font></div><div style="font-weight:400;font-size:13px;margin-top:0px;color:rgb(80,0,80)">Email: <a href="mailto:todd@toddvernon.com" target="_blank">todd@toddvernon.com</a></div><div style="font-weight:400;font-size:13px;margin-top:0px;color:rgb(80,0,80)">LinkedIn: <a href="https://www.linkedin.com/in/toddvernon/" target="_blank">toddvernon</a></div></div></div></div></div></div></div></div><br>

<div dir="ltr">Hi there,<div><br></div><div>Any special tips for fixing a dead SparcStation 1 power supply? the 5V comes up, but the 12v line does not.
