I recently acquired a used HP/Agilent 6033a power supply, this is my first power supply as I am just getting introduced to test equipment. The unit did not come with a power cord, so I used an extra computer power cable I had as it has the same connector and the power rating is the same. When I power the unit on, the fan turns on, but thats it. No LED lights or anything come on on the front panel. I have found a copy of the operating manual online and have skimmed through it, but don't believe I have seen anything in there regarding this issue. I believe I have given the unit ample time to warm up (going on an hour now). So my question is: how would I go about troubleshooting this issue, or is there somewhere I can send the unit to have it serviced? the serial number for the unit is: 2728A-03058
Any help would be greatly appreciated.

I'm not a 6033A expert but can recommend a few ideas:
1. Power cable shouldn't be causing the problem, these are pretty standard.
2. You can check for any power on the back terminals, even without the front panel working.
3. If available, you can verify if the main board working correctly by sending it a command over the HP-IB. You can send some simple commands to change voltage and amp outputs on one terminal.
4. Download the Service Manual http://cp.literature.agilent.com/litweb/pdf/5959-3346.pdf and go through the Troubleshooting steps (page 29).
The power supply is still sold and service is available. It is best to debug as much as possible by yourself, and verify the problem before sending to our service center. A simple problem could be fixed with a new part.
Good luck!
