![]() But it is not possible to help you to do this from a forum.You will have to do a lot of reverse engineering. (high voltage probe recommended) 7) check and repair the trigger and time base. ![]() 6) check and repair the focus and brightness circuits. He has been active in the Chinese literary scene in Singapore since the 1970s, and has published 17 works of prose, fiction and childrens literature. Lim Hung Chang is also known by his pen names Lin Yifei and Lin Gao. For the rest, it will be necessary to follow the usual principles: 1) check the supply voltages 2) repair bad contacts and bad solder 3) repair the damage of previous repair attempts 4) with the type of crt, check the pinout and measure the voltages of the vertical and horizontal deflection plates (Caution: there is high voltage on some pins of the crt) 5) Check horizontal and vertical amps in X / Y mode and repair them. To write, you need to focus and you have to give up certain material temptations. One positive point is that there is high voltage. If it were Hung Chang OS-620, that would be easy, I have already repaired several.* But this model, I've never seen it. It seems that there are multiple failures and even problems resulting from attempts at repair. ![]() Without service manual or, at the very least, schematics, it seems difficult to repair this oscilloscope.
