GC heated zones are not working

[JI2002]

We have a 5890 series II GC with TCD and FID, when the GC was started today, all the heated zones including injection port, oven and both detectors stay at room temperature. There is no fault messages, it only shows oven temperature not ready, injector A temperature not ready, detector A temperature not ready and detector B temperature not ready. Powering on and off the GC didn't help. Rebooting computer didn't help. Fuses on the board checked out OK. Any ideas?

Agilent service representative came in and fixed the problem by replacing the motherboard.

Thanks for the update. I'm glad that it's fixed.

Agilent service representative came in and fixed the problem by replacing the motherboard.

So the 5890 motherboard was still available....

The service guy had only one motherboard for the system. He has been in the business for a long time, so he has parts for old GCs.
