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

Hi!
Sorry... I have no manual for this scope right now but I've had similar problem with one of my scopes. There was a cold solder joint on the HV-board. If you have some electronics skills I think you will pin point the problem by measure. Beware! There are voltages that could kill both you and your multimeter! The latter will go up in smoke unless you don't have a proper HV-probe attached. I'll check at work, I might be able to fix the manual you requested.

Mr Brown :)

Is it just me or do others wonder whatever became of:

"Please" and "Thank you" ?
