Novice question about lcd inverter testing

[pawel123]

Hello,

I found such comment on the internet: "The inverter is designed for an RF impedance, not to drive into a simple DC resistive load like a multimeter, and I wouldn't be surprised if that voltage test has ruined more than a few inverters."

In youtube videos, I've seen people investigating a "living" inverter using a multimeter. I would like to know if we can damage "living" inverter board by touching the multimer(oscilloscope) needle to the wrong smd element?

They are checking INPUT voltage and BL/ON signal.

It's the OUTPUT voltages to the lamps that can destroy your meter.
