Help with my first CRT Monitor!
So guys, I recently started researching various monitors in my area, and today I ended up buying my first CRT, it's a Nokia 447Pro, the "best I could find around here" (€35), I bought it from an elderly gentleman, who claimed to be the first owner and that he used and cared for the monitor well.
The problem is that after work, when I plugged the monitor into the socket, after about 20 seconds this started happening and I didn't want to force it anymore and I turned it off completely. I haven't tried plugging anything in to get video because I'm afraid of damaging it due to these small crackling noises and the screen resetting.
I would like to know if anyone knows if this is normal, or the causes. Please give your opinion on what you think of this monitor; its condition seems to be very well cared for!
