Acer Nitro XZ342CUPbmiiphfx, monitor randomly turns off and on, could it be an electrical issue?

Sometimes the monitor turns off and turns back on immediately for once. I have already written this problem but it has not been solved. my father says it could be an electrical system problem being old. What do you say?

It depends on whether it's actually turning on and off or just going to a blank screen for a bit. Turning on and off would do something with the power light at a minimum and would point to a loose or broken power supply, most likely. If it's just going blank it might be switching screen resolutions, which gives a few seconds of blank during the change.

If your Acer Nitro XZ342CU monitor is randomly turning off and on, it's a common issue that can be resolved with a few troubleshooting steps. Start by ensuring the power cable is securely plugged in and try a different cable. Also, check your monitor's power-saving settings in the OSD menu and the PC's power settings. Troubleshooting Steps:-

1. Power Cable and Connections:

1. Secure connections: Double-check that the power cable is firmly connected to both the monitor and the wall outlet. 
2. Test a different cable: If the issue persists, try a different power cable to rule out a faulty cable as the cause. 
3. Video cable: Ensure all video cables (HDMI, DisplayPort, etc.) connecting the monitor to your PC are also securely connected. 

2. Power-Saving Settings:

1. Monitor OSD menu: Navigate to the monitor's On-Screen Display (OSD) menu and check for any power-saving settings or timers that might be causing the monitor to turn off. 
2. PC power settings: In your operating system's power settings, ensure that the monitor is not set to automatically turn off after a certain period of inactivity. 

3. Monitor Reset:

1. Power off and unplug: Turn off the monitor, disconnect all cables (power and video), and press and hold the power button for 10-30 seconds to discharge any residual power. 
2. Reconnect and check: Reconnect the cables and turn the monitor back on to see if the issue is resolved. 

4. Other Potential Issues:

1. Heat: Ensure the monitor is well-ventilated and not overheating. Overheating can sometimes cause a monitor to turn off. 
2. Dirt or debris: Clean any dust or debris from the monitor's buttons or vents. 
3. Faulty components: If the issue persists, it could be a hardware problem within the monitor itself, such as a bad capacitor or the monitor taking too much power. 

5. Seek Professional Help:

1. Warranty: If the monitor is still under warranty, contact Acer support or your local Acer service center for repair or replacement. 
2. Local technician: If you're comfortable with electronics, you can attempt to diagnose and repair the issue yourself, but if not, it's best to seek professional help.

First check the power connection by using a different outlet or power strip to rule out electrical fluctuations. Ensure both the power and display cables are securely connected, testing with different cables if possible. Updating graphics drivers via Device Manager can help prevent display instability, while adjusting power settings in Control Panel → Power Options may stop unexpected screen blackouts. If available, try connecting another monitor to determine whether the issue lies with the display or the laptop’s output.
