2012/9/18, Roy Phillips <[email protected]>:
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
Roy
