ASUS ZEN AiO Z272 27" LCD Display Went Dark

[DTGMI]

Asus Zen Z272 user - have (2) in different offices - love them.

Today my home office AiO's Z272 screen flickered a couple times and went 100% dark.

As an IT tech and we have a repair lab in our telecom/data business - we run across various issues like this from time to time.

So I unplugged the power ... waited a few min for the capacitators to discharge and before pluggging power back in - held the power button for 45 secs or so. Then plugged power back in - pressed the power button and the small front power LED by the SD card slot shows ON ... I get a small amount of screenlight on the bottom left edge ... and that's it. I tried this cycle a few times then just left it running.

I went to my other PC and we use ScreenConnect for remote access - so I remoted into that Z272 and it is running fine .... just no display output on the local screen?

Any tips? I couldn't find anything helpful from a Google search.

Thanks!

Sounds like the back light went out. Take it for repair or replace.

Sounds like the screen inverter has stopped working for whatever reason and, as a result, the backlight won't come on.

Luckily, inverters are small and relatively cheap to replace, if necessary - they're just a small board really - so usually much cheaper than any other type of screen repair.

Just to elaborate on what is mentioned above, usually if you take a flashlight and shine it up at the screen at an angle you will be able to see whatever is being displayed if it is just the inverter that went out. It will be dark and hard to see but visible. If you dont see anything, then it may be the LCD/LED screen, broken/loose video cable, or bad graphics from the mobo.
Since you can remote in, odds are good the motherboard and drivers are fine.
