Agilent MSD - no signal from run

Hi,

I've got a manual injector GC-MS with a few issues that we can't figure out. I've set up a new method, everything straightforward (acquisition only mode, set a data file, temp programme etc.) which I can load onto the GC and the MS with no issues, I run through the method with no problems, oven ramps as expected etc. but the filament never lights on my mass spec and when I go to open the data file there's nothing in it. The logbook said that the signals from the GC and the MS were not acquired but we can't find any reason for this to be happening? Like I said we set the GC to run acquisition, I can't find any MS configuration settings that will tell me anything different.

Then we tried running a method that we know works to see if the filament lit up after the solvent delay - nada. The filament still works because it lights when we tune it and the peaks we get from the tune are great.

Am I missing something?
Help appreciated!

Usual problem I suspect - if you don't see the solvent delay message from Chemstation the only cure is to power cycle the MS ( a couple of seconds seems to work).

Turning it off and on again did indeed work - I hate technology!
