I'm taking the monitor out of my Blast to clean everything, so I want to discharge it. I have a high voltage probe from BK Precision. I connected the ground clip to the metal on the chassis and put the pointed tip under the anode, but didn't get any reading on the probe or hear anything. I assume it's already discharged, I read somewhere that the Blast monitors have a bleeder circuit to discharge automatically. It's a Nanao 2930, I don't see a manufacturing date anywhere. I've had it off for a while, I think March 24 was the last time I powered it up. Think it's safe? I'm just worried I'm not getting the probe in far enough or something. Does this look okay? Any other tips to ensure it's discharged?
