Ever since a couple of days ago my Acer AL2423W monitor has this issue where, upon turning it on, it usually only displays the Acer logo faintly and then just all black, versus that previously it would display the Acer logo until it becomes more bright and then the display comes in correctly. These days I have to turn the monitor on and off until it feels ready to take the Acer logo all the way from faint to bright and show the display correctly. Most times for about 10-30min it refuses to take it all the way, leaving me turning it on and off until it feels ready to complete the process.

I took great care of my monitor over the past 5 years or so. It's a beautiful 24" that cost me ~$500. Why can't Legacy models be scheduled for repair? Are Acer monitors meant to last only ~5 years?

Could you help me?

LCD monitors have a life expectancy is between 50,000 and 60,000 hours of use. So if this is at least five years old you have 43,800 hours on it. I could be nearing it's life span.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

A backlight getting hard to start towards the end of its life is a possibility as dc3 says, another frequent cause can be bad electrolytic capacitors in the power supply/inverter board. Not everyone will think the cost of a repair is justified if charged out at commercial rates, but many folk with soldering skills or a technical friend tackle capacitor replacement. If that's the cause in your case, you may be able to resurrect the monitor.

Just as an example, the link below shows the power board for your monitor and the capacitors it uses:
