LG Monitor Stopped Working

Jon Jon

The strangest thing happened.

 

Out of nowhere, my LG monitor just stopped outputting a signal.

 

I cannot even access the monitor menu.

 

Neither the HDMI input or Displayport inputs are working.

 

I even disconnected the power and let it sit for a minute or two and reconnected.

 

All I can see is the backlight come on, and that's it.

 

I think this thing is dead, and sadly it is a year out from warranty, and even with my credit card additional warranty.

 

This is a real shame.

 

All suggestions are welcome!

 

Thank you!

What a bummer.  Try a different power cable....

Sadly, it has a proprietary connection.

Hmmm I mean its a long shot but possibly the power unit adapter is dead.  I would def see if you can get your hands on one.

I so far tried plugging the adapter directly into the wall with the same result.

 

It is crazy out of nowhere.

 

Sadly, I think I am stuck and may need to just buy another or change vendors.

 

What a shame!

 

Any recommendations? I would like to stick to ultra wide and 29 inch if possible.

Update:

 

I think I will pick this up, as I really don't want to buy LG again, and the reviews seem rock solid on Amazon:
