PC Peripherals Crt Issues

[Spy king]

Hello!

Recently have noticed some issues with my dad's old Crt.(SyncMaster 793s)

Tried degaussing, but there hasn't been any improvement.

What could be the cause for this? The desktop is actually a solid gray originally.



-Thanks

Seems like the picture tube have developed some fault

Damn, I sure hope not! I think this happened when the monitor was moved while it was on. I shall try checking the VGA cable and check tomorrow.

Yeah, but really tiny ones that can't really effect it. Pluss they are magnetically shielded. I shall shift them and check it the problem persists too.

Is there any ups near the monitor, because same like speaker, the ups also affect CRT monitors.

@Spy king, i doubt about the picture tube, because of its age.
