Help LX90 Autostar quirk

I wonder if any LX90 owners out there can help me?

Had my LX90 for over a year now and the Autostar has a quirk - at
least one of the menus (Object - Solar system - to view the planets)
has never worked. It doesn't even get close, it's way out looking at a
different part of the sky to where the object should be.

In all other respects the scope works fine, aligns no problem, usually
use it in Guided Tour - Tonight's Best mode, and it finds the objects
every time. Been doing this for over a year with no problems, but the
Objects menu fails to find every time.

I thought it may be due to an old version of Autostar, so I updated to
V30E tonight and still the same, Objects menu will not work. I
typically use the scope several times a week so am pretty familiar
with it, I've trained the drive, checked the battery level etc. but
still no joy.

Can anyone confirm that 'Objects - Solar System' works on their LX90
and, if so, any thought as to why mine doesn't work?

Thanks,
Darrell
