Monitor testing

[JoeTechie]

I have some crt screens that I need testing, don't have any game boards to hook up yet, but can the crt be tested without any video signal going to it, or would that cause any damage to it?

Sorry for the newbie question 😅

Some issues regarding the video input. You can Only test that tube/chassi is powering up.
You wouldn’t want to leave brightness to high/ monitor left on to long if the bars are showing through screen could screen burn in a short time period.
