Cube Troubleshooting


one of cubes started giving me trouble other day-specifically in it's stone-cold dead.

particular 1 has sonnet 800ghz cube processor , 2mx video card.

in case, plugging in gives no led on vrm, , no response pressing power button. i've tried powering via display same response. did pmu reset.

i've ruled out bad power brick(traded cube-the dead 1 still dead, while working 1 continued work). did same vrm, , confirmed "dead" 1 has vrm(and didn't boot 1 borrowed working cube).

don't know go here trouble shooting. think i've ruled out common problems-can suggest go next?

should add cube hasn't been used in month, working fine last time shut down.
 

temporarily forget know computers , remember know electronics. loose connection. electrical test light may useful. in other words make sure electricity going it's supposed to.
