    [Dead] HP LJ M604 No Power

    The customer said that it lost power a few months ago then they let it sit for a few days the it powered back on and lasted a month or so. Now they were running a job from there PC and during printing it powered off and will not come back on. I checked the outlet and power cord. I suspect the controller (Formatter board). Is this a common problem with these machines ?

      Agree, check the fuses on the power supply board. If fuses are good, then replace the power supply board. Also, doubt the formatter board is bad.
