Strange Lines in IBM 5153

Recently bought this IBM 5153 for my PC. Was looking to get a CGA card to properly test it, but before I did I noticed these weird lines when the monitor is powered on with no input. Is it toast?

That looked like a vertical linearity issue. Send it a proper signal and adjust V height and V linearity. If it doesn’t adjust adequately, it’s time for repair.

Got it, I'll give it a test.

Reseat the video card or try new/ different cables

I'll get a card and test it.
