Hello There!



Has someone Service Manual for above mentioned oscilloscope and send me in PDF file (or similar). Schematic diagram will also help. Actually, I cannot adjust anymore "focus" and also "intensity" - became not adjustable. Instead sharp line on the screen I have "smear" line...



Regards, Josip

Check the resistors in the path of those controls. They go up in resistance and cause that problem. If they are OK, the CRT may be failing.
