agilent 7890A sudden power off

[chem.eid]

Hello,

I have a problem that my Agilent 7890A GC had suddenly powered off and when i tried to turn it on it goes off after the self-checking and displaying the Agilent technologies logo. What can I do ,please?

Thanks

A '' thermal shutdown '' error may cause this , possible causes : faulty cooling fan ( at the back of the injection port ), faulty temperature sensor or heating element.

Is Agilent logo the only information from GC display ?
Any information about Power On Selftest ?

Thank you guys for the quick support

this is what happens at the self-test

then the Agilent logo displayed then the device turns off

no other notifications are displayed

there is 2 red and 1 orange lights at the back of the device

I don't know what does this mean ?

I was hoping for a kind of error notification on the display.
Unfortunately selftest won't help with diagnosing.

[chem.eid]

so does this problem require changing the hole main board of the device ?

As mentioned in the other thread, can you please check your line voltage?

This problem will require the replacement of the GC mainboard.
