Cannot Turn on Monitor and Standby Red light is gone
I used my monitor, on evening, without issue and I had turned it off using power button on bottom right of screen. then, the next morning, the "stand-by" light which glows red when monitor is off, was not on. I attempted turning the monitor on utilzing the remote and the power button on the screen intself, but still it remained completely off with no standby light of red or "on" light of green. i tried different outlets, switchin light switch, readjusting power to insure plugged in at BOTH ends...perhaps there are some other common sense things that i cannot think of, or maybe there is someone out there who knows of this type of affliction and has a recommendation or solution. thank you for reading.

If it doesn't turn off by holding the power button down for 10 seconds, then it cannot be turned off by the power button alone, like most modern lcd monitors. Most modern monitors goes into standby mode. To completely cut power, you must unplug the power cable.

It's normal; if the set do not show a screen at this time. The red light indicates that the set is in standby mode, and it will off, when you hit the standby button again, and the scree will get live. http://electronicshelponline.blogspot.com/
You can try to do the monitor self test. Monitor Self Test: 1. Physically test the monitor autonomously from the computer.2. Switch both the monitor and the computer off, and then disconnect the VGA cable le from the computer.3. Turn the monitor on, pressing the power button for about three seconds. The self-test screen will come up .4. If the image is clear, bright, and shows red, green, and blue, the monitor is working properly. Video issues may be due to the video resolution in the computer, and not the monitor.5. If the image is not apparent and intense or the colors are not accurate, then the trouble is with the monitor or some of the (OSD) settings. In this case, test your particular monitor's information for OSD. It is always important to check the color of your power light for so you can distinguish if the monitor is defective. Getting red lights on the the power panel states that the power section of the monitor is faulty.
sounds like a power issue with the monitor. try to remove and reconnect its power cord. If same thing happens, try using a confirmed working power cord like the one you use with the computer and make sure you test it out using a confirmed working power outket. If it has the same issue, would mean you need to get a replacement monitor. Refer to the vendor if it is still in warranty.
The STANDBY light will flash if the television detects an issue within the
television. Some of these issues can be resolved simply by following the steps
below to reset the television.
If the issue is still unresolved after following all of
the troubleshooting steps, service may be required. Please note the number of times the
STANDBY light flashes and relay that information to the service center.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
NOTE: If the television is
plugged into a power strip or surge protector, remove it from the power strip or
surge protector and plug it directly into the wall outlet. If the issue is
resolved, the problem is with the power strip or surge protector and not the
Have similar TV. If it is set to the PC source, it goes into standby when there is no signal, like a regular monitor. Even though the monitor is in standby, you can still press the Source button to change to, say, HD input, and will use the familiar on/off action when pressing Power on the remote.
In order to fully answer your question, a number of needful things must be inspected, reinstalled, confirmed, & tested:
Reset. Try the reset button. You could use a paper clip to reach the reset button through the pin hole in the lower front left of the Zonet KVM unit.
Inspect connectors. Each data/input/power connector/port requires all of its pins to be present & straight for full functionality.
Inspect the entire length of each cable & cord to ensure that each has no damaged area.
Seat each connector in the appropriate port of a computer that will be accessed via the KVM unit.
Electricity. Inspect all affected devices & confirm that each has sufficient, uninterrupted electricity.
It is possible for a Zonet KVM unit to display channel lights without direct power to the unit, but you should confirm that the unit is getting sufficient, uninterrupted electricity-directly through its own power cord. Unplug the KVM power cord & every connector & reseat each one (this performs a power reset on the KVM unit)-making sure that each connector is in the correct location (not just where it originally was). Thus, make sure that the keyboard, video display (monitor), & mouse are on the output side.
Press the power button on your monitor. If it does not turn off the monitor's power status light (Off/On/Standby), then remove the power cord from the monitor & reseat it-to reset the monitor's hardware. If it does not turn on the monitor's power status light, then the monitor is either not getting enough electricity or it has a malfunction which requires troubleshooting & fixing (possibly through a fixya.com thread for that monitor model).
Unlike USB devices, PS/2 devices usually require device connection prior to turning on that device. With that said, connect the keyboard & mouse KVM channel cable connectors to the computers & then turn on those computers that you intend to display through the KVM-connected monitor & then turn on these computers.
Any computer that does not turn on has an issue that requires resolving (just like a monitor that would not turn on).
Sometimes a keyboard/mouse interface issue can be resolved by replacing that interface device.
The KVM Unit. When all else properly connects & performs, what does not properly connect & perform has the issue &, hopefully, that can be repaired without having to replace it.
