My acer x223w monitor goes black and the blue light stays on what could it be??

Why don't you contact Acer and pose that question to them?

I disagree with ikkenom only due to the symptom of the flashing blue light. This would indicate to me that the monitor is not getting any display signal and is in sleep mode at least the is what happens on my Samsung monitor. Used to be that they use a two color led in the monitor, green when ON and getting display signal and amber or orange when in sleep mode. I would check the computer by trying a different monitor. If you have a second monitor, great, if not, maybe a friend will let you bring your computer over and try the computer with their monitor. Could also be a display adapter setting. Do you get any change when you first turn on your computer? i.e. Do you get the BIOS or manufacturer screen when first turned on? Also if you disconnect the monitor cable from the computer and power cycle the monitor, do you get a No Signal display for a few seconds before the monitor goes black and the blue light starts flashing?

Let me know what happens with the testing above or if you need further instructions to carry out testing.

Thanks, Jim

The white connector is to connect the monitor digitally. The blue connector is to connect via analog.

try changing video cable

There is an "inverter" component inside the LCD monitor,
that creates all the "brightness" of the image.

That part is failing, and is becoming intermittent.
It's about a $20 part to replace, plus $50 for a qualified TV/computer technician to open the monitor, replace the part, and reassemble the monitor.

That is normal condition, yellow = no video signal from PC since PC is off or PC in standby mode.

uninstall the driver from ur display in the device manager, u shud be able to do this thru safe mode. it seems the lcd driver is not compatible with thw m/bord

I have a dual monitor system, both are the x223w. Same problem but only on the second monitor. Backlight shuts off.On/off light stays blue. I have to turn off the monitor and turn it back on. I returned it and Acer could not find any problem so I got it back. No problem for awhile and now a few times over the past couple days. Not good...

it happened may b due to inproper power supply.So check the monitor data cable & other connections also.
