Is my monitor (Benq XL2730Z) dying?

[dsunfish]

Monitor has been working flawlessly for 2 and a half years.

This morning, it suddenly began 'glitching', with the image heavily distorted (see picture). Turning off and unplugging / re-plugging every cable fixed the issue.



However, now the issue reappears after a short while (2-20mins) whenever I use the monitor. The issue does not affect my other monitor connected to the same PC, and it also appears when the PC is unconnected and I am using the benQ monitor as output for my PS4, so I believe it is an issue with the monitor itself.

The issue begins with a few small flickering horizontal dots at a random part of the screen. Then, the whole screen will begin flickering with massive distorted lines.

Does this mean the monitor is dying, or is there something I can do to fix it?

Is it under warranty? Hear any buzzing noise from back of monitor? Tried to factory reset monitor in settings?
I assume that if you replug cables and cycle power of the monitor that capacitor is bad but im unsure.

I've tried the above. In another attempt I noticed that as I plugged in the power cable there was a buzzing noise and some clicking which did not sound good.

If possible take it to repair shop and let them diagnose if you dont wanna take risk of breaking lcd when dissasembling.

As an update, I've tried different power / input cables all to the same effect. Interestingly, when the screen distortion happens, if I turn the monitor off and then on again after ~5 seconds, the issue is gone for the next few minutes. Would this match up with the theory that an internal component like the capacitor is the problem?

From me is a very big yes, its usually that way.
