Trinitron KV-1326R not responding to power.

[DordTrain]

Picked up a trinitron kv-1326r. I plugged it into an outlet in their garage at the sale itself and it didn't power on, but, as I unplugged it, I heard a noise, like a click.

So now I'm home and it's just not functioning, no click anymore. I am hoping to get it working. Taking a look inside, it's very dusty but I see nothing visibly broken, missing, or melted.

Is there a way to troubleshoot? Maybe with a multimeter or something? I would love any advice, thank you all!
