My problem is that the waveform is not stable...
I think it have trigger problem but i don't know which part is damaged...
The Trigger source switch is not working...
when i change trigger source nothing happening.
even i used LEVEL Volume to have a Stable wave form without moving but it made no difference.
thank you for replying and help.
and sorry for my bad english.
