LG OS-3040D Oscilloscope Calibration

[Shark]

Hi guys!

This is my first post on this forum. I have an LG OS-3040D oscilloscope and would like to calibrate horizontal and vertical deflection.

This oscilloscope is similar to models OS-3020D and OS-3060D. It is also rebranded as Conrad, EZ Digital and Goldstar.

I was able to find user manual on Google, but no service manual, where I could find out which pots to adjust. I welcome any suggestions Thanks.

Hi,
i know this topic is fairly old. But hopefully Shark is reading this. Or someone who is interested in the schematics. A few days ago i have buyed a broken Voltcraft OS-3020D with all schematics, for round about 30 €. Today i fixed it with a bit of tin solder. The storage mode doesnt work.  On a pin of a SOT-23 transistor in the D/A circuit, was no solder. 
(by the way: the PCB is labled very nice)


However, here are the schematics  ...

Hi 128er, wasn't expecting anyone would have found it as it's been so long. Thanks a lot!
