Hi everyone
I recently got a leader lbo-508 oscilloscope
The scope doesn't show anything on the screen
I have done some measurements
Tp1 -15.12v
Tp2 15.11v
Tp3 197v
Tp4 297v
I don't currently have a meter that it rated high enough for tp5
Tp3 and tp4 are a bit low I think this is due to C115 which has started to leak
D116 and D117 have cracks on them and measure open circuit (with my multimeter)
I am planning on replacing D116, D117 and C115
Advice and/or recommendations please
