I turn my x223w on and in a minute its turns it shuts down, i can't get it to stay on, it like it goes to sleep

You can't, it's a 'feature', set for every 7 minutes of inactivity. However.....

I don't think you can turn off sleep mode. However, after the calculator goes into sleep mode, to return to where you are working just press the C/CE key (red key bottom left). The calculator will return to where you left off.

Aug 10, 2018 - CANON MP25DV TURNS OFF EVERY 7 MINUTES. HOW TO STOP THIS? - Office Equipment & Supplies.

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

When you shut off your PC do you:
1) Give it enough time (could take from 1 minute to 10 minutes) to shut down completely (easy sign is if the fun continues to run or lights are on)?

2) Clicked Hibernate or Sleep OR closed your laptop screen before it completely finished shutting down (this could put the PC to sleep and it would remain on, so the lights would remain on, until you woke it by moving a mouse, flipping the screen back and forth for a bit or pressing the start button (not holding))?

3) Have it plugged in (depending on the model, a light might stay on if it is charging even if it is not on(probably not this one since you said it turns off after a Hard shutdown (don't do this since this damages your computer and will make it break down after continued use)))

Is it going to sleep or is it actually shutting down? Do you have to push the power button to turn it back on? Just a thought - if you have Windows 7, go to Start, Control Panel, then System and Security. Now check 'Change when the computer sleeps' under Power Options. Under Edit Plan Settings, what do you have for 'Put the computer to sleep'. Does '20 minutes' show up in the box? Open it and change it to 'Never' and then Save changes. If this didn't help you,maybe someone else can.

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

It's likely that the TV will require service since your troubleshooting steps didn't resolve the problem. If your TV is smaller than 30", you may carry it in to the retailer of purchase for repairs. Otherwise, service for your TV can be obtained by calling 1-888-237-8289 in the U.S. or 1-866-237-8289 in Canada.

Normally a monitor will come out of sleep mode merely by moving the mouse or hitting a key on the keyboard. It all has to do with your power settings. If in Windows, click on START/ControlPanel/Power Your Power settings determine how long your monitor stays on as well as hard drive disks when computer is idle. Just select a longer period of time or "Never" for monitor shut off settings.

Go to your control panel, click on your power options, Select "Never" from the drop down menu next to "Turn off monitor:"

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...

check your windows settings. They are in your power settings. You can adjust your computer to whatever you want.
right click on destop and goto properties, then click on screen savers tab.. see the power settting button now?? You should be able to tell it what to do for everything to do with Power.
