TP25 shows -9.70V - no trace

I just want to see parameters were set to normal. Sometimes the scope could appear no activity with some settings.

Here's a pic of when it is on.

I can change values with the buttons etc.

Please try VPOS alignment and change trigger mode to AUTO. Do not us SING which requires trigger to do waveform update.

By the way, the kit you purchased was a counterfeit one.

Okay, I had something like a trace now :O Pretty erratic before the screen went white. I'll have to debug that.

Sorry I wasted your time on a counterfeit product problem
You really should work on expanding your distribution network, so we can buy your legit (and quality) product
