Test/borrow another monitor/cable, that way we will know if it is the monitor or other.

If the switch is mechanical in operation, I.e. there is a sense of physical movement merely a touch action, then it may be the switch.

Mechanical switches can fail when the toggle bar within snaps; or, and less common, the internal spring, if the switch is that design, that can fail. If a simple touch/press type they are often poorly made and fail.

I have a Roberts radio (a UK brand which one was truly reliable brand, but then was taken over by whomever, and is no more what it was...) on which the on/off switch (actually a button which is press to operate) failed on the model I have for almost all owners. I suspect the same switch failed on other products too. if one presses that button variously it may operate swirchon or off as appropriate; but takes more than few attempts to get it to work.

What make and model is the monitor; and if possible describe the type of switch?

Does the power cable connect directly to the monitor or is there an external power supply? Model number of the monitor would be helpful. http://www.v7world.com/us/products/...

If the monitor has a direct power connection (in other words, no ac adapter) & it shows no sign of life when pressing the power button, it's probably time for a new monitor. Unless you know how to fix it yourself, it's probably not cost effective to take it to a repair shop. You should be able to find a decent replacement for under $100, even cheaper if you go with refurbished/recertified.

I couldn’t find any monitor used no the information you give. What is the make?

Is the power cord a removable cable which plugs nto the monitor or is it permanently attached (which is not that common these days).

Regardless, you mentioned your initial post that when the monitor was working that it often wouldn’t switch off. My money is on the switch being duff/faulty. Not usually an expensive item, but the Labour cost to replace it might be more expensive. A check with a reliable repair shop wouldn’t hurt to see what they would charge to repair the monitor (replace the switch). But as suggested it might be cost effective to replace the monitor?

I found it listed at Walmart. VGA & DVI only so it's an older model: https://www.walmart.com/ip/V7-LED21...

Presumably a detachable mains/power cord/cable,

Me thinketh (I do occasionally - between sips of sherry or port...) that it is the switch itself that hath failed; based on the problem of it not switching "off" let alone "on"...

Getting the replacement switch might not be a readily viable option; unless the monitor used a relatively standard switch. But it could be by-passed and the monitor simply switched on/off at the wall outlet?

I note on the Walmart link that the display is actually an Asus... Possibly one might be able to get a switch from them; and have competent techie to install it?

From the description in the original post, it is clearly the switch.

I have a TV remote control on which the power button was absurdly
and exaspiratingly flakey. It took more and more and more presses
to get it to work. After years of this I finally pried it apart (difficult!)
and cleaned the contacts on the PC board and the rubber sheets
that the buttons are molded into. Works fine now.

Even four years is not that olde for monitor. I have two that are much older than that and still working.

If you still have faulty one, perhaps investigate how much to replace the switch? Equally see if you can determine how to gain access to the switch and then simply bypass its connection. A wee bit of connecting wire between the relevant pins (likely two sets - one live, one neutral) would then allow it to power up. Switching on/off now being at the wall outlet?
