Hioki 3532-50 LCR Repair (One major problem solved, SM still wanted)
TERRA Operative:
I found a Japanese user manual for sale here on Yahoo Auctions, but it's not the service manual... It's the same one in my google drive link above. :(
At least it shows that manuals are being sold, so I'll keep an eye out, we might find a service manual one day...........

No response from the hioki distributor so far, next week I´ll order the touchpanel from the (far east) ebay-seller.
The 5V LDO is on it´s way and I think I exchange the bnc sockets too, as they´re a little bit "rusty" looking.
Finally clean the contacts of the display and then....Test if the display light is ok.
(you must turn it on/off in the menu, the menu I can use when the new touchpanel is assembled)
That all could last some weeks... ;)
But it will be surely worth it.

No good news from them...
Production ended in 2015, service support ended in 2021.
This means that since that date there is nothing more for it, no spare parts and no documents like the service manual.
That, in turn, was only available for authorized service workshops.
Fortunately, the device does not have an electrical defect in the sense that it requires the manual.
But maybe I'll be lucky someday and get it after all.
Now I want to order the panel from the Ebay seller, but he is on "vacation" until February. :P

Might have to get friendly with a tech at a service center or two... :)

Are you sure you want to change the BNC connectors? Would think this might have an effect on the calibration, and without a cal manual, and the necessary cal standards, might not be a good idea!! Sure you may not know the cal state of the instrument as is, but changing the connectors seems it will just increase the uncertainty, altho look nicer.
After you get the LDO and new front panel installed, maybe just clean the connectors as best you can for starters. BTW the original panel after you cleaned/processed it doesn't seem too bad IMO!!
Best,
