First of all - welcome to BC !

 

When you have the second screen connected, right click on an empty space on your desktop and then select 'Screen resolution'. both your screens should show up in the window that opens - make sure that the external monitor is the one selected.

 

Have you tried changing the cable you connect the external screen with ?  You can probably just borrow one for the time it would take to test this possibility, cables can go faulty.

 

And finally, it is just possible that your CRT screen is faulty, especially as you say it is second hand. And, if you mean Cathode Ray Tube when you say CRT, these screens are all getting fairly old. I appreciate that money can be in short supply, but you can pick up ex-lease LED screens quite cheaply as well, and they will probably be newer.
