Hi,
I have a 3581A that was working a few years ago when I purchased it
off eBay (yes, yes, I know).
I went to power it up recently (not having powered it up for about a
year) when
I noticed that the inner two LED digits are not lighting. I'm not
talking about
missing segments, but the inner digits not working altogether:

Working the frequency control I can see the lighted digits changing,
but that's
all.
Is this a repair that is straightforward? I consider myself handy.
Otherwise,
any tips/advice on where to have this thing sent for repair?
Thanks,
Chris
