Hi everyone .
I have been recently logging in using facebook and have decided to join this board witch i find pretty interesting .
So my problem is with an old hung chang 5502 oscilloscope that was still unused though , i have used it mainly for monitoring some high frequency signals coming from switch mode power supplies pwm ICs .
So i have checked one day one and i have shorted two pins of the ic witch resulted in not reading any voltage amplitude any more on both channels even after adjusting the trace rotate pot .
So now i have two theories :
Probe is bad and scope only needs calibration ( witch i hope )
Internal problem on some PCB ( :shock: )
this is the display i got after the event :
