I have a faulty HP8903A. Despite the excellent Agilent manual archive, and other sources that I am aware of – I cannot find any source for the Service Manual – can anybody help ? The unit starts up and displays all digits as with the normal “self check”, but stops dead at this stage. All voltages would appear to be normal. It has a sequence of four yellow LED’s on the Processor PCB, which are active – but what is the ‘normal’ state for these. This is not an easy unit to access without the vertical series of PCB’s without extenders – any help would be much appreciated.
Thanks

You will likely have better luck asking over on the HP_Agilent_Equipment
Group.

If you dont find a free one we have a professional quality scan for a
very modest amount
