Sencore lc 102 repair
« on: September 20, 2022, 11:51:28 pm »
Anyone know of someone that knows how to repair an lc-102. In 2019 mine fail to start up. I found an older guy that had done repairs for Sencore. I sent it to him and he started on it and put it to the side waiting for parts. His health would cycle from okay to not good. Well, he died last week and his widow is sending the unrepair back to me. Really would like to find someone that has some experience on this unit. I was told that the problem I have is a real bugger to fix and not a simple problem.

Have you asked Choice Electronics?  http://www.choicegear.net/
They're kind of the source for Sencore parts though I'm not sure they do repairs.
Not cheap either but they may be able to point you in the direction of a repairer.

Looks like they do repairs, here's their price (might be outdated) according to their site:

Contact forum member "Sencoretech".
He has officially repaired many of the LC102 and may can help you better than anyone.
There are 3 kinds of people in this world, those who can count and those who can not.

Please ask them to share what they found on the forum, because I'm sure lots of people, including me, are interested in learning more about servicing the LC102.

I forget where I found the schematics?  here perhaps?

I recall they were (originally) 3 large sheets and had been overlap scanned into multiple (23) 8.5x11 scans.    I used a program to stitch them together and discovered that two of the sheets had a poor overlap so I was missing a small portion.

Not sure if anyone has a different better scan?

I see three files with schematics, probably all from the same source material, on BAMA:
Sencore_LC102_Auto_Z_meter_Operator_Manual.pdf
Sencore_LC102_Schematics_112_pages.pdf

These contain what appears to be the same schematics, with some pages rotated relative to each other.

Sencore_LC102_Schematics.zip: This file contains the stitched schematics with some of the missing parts filled in, and the rest as white. The resolution isn't great, but looks mostly legible.

I think they are copied from  KO4BB  website...  and i was the first one (to my knowledge)   to have stitched them together  with the same section loss ... and yess the quality is discutable

the Sencore_LC102_Schematics.zip   was done by me

I never found  a better quality  for them .......


Anyway   the important thing is to have repos  of the documents and firmwares dumps for them
