PC monitor image flashes once on startup, then stays black.
My PC monitor image flashes once on startup, then stays black. If I wait for around 15 minutes and click on the input/exit button on the monitor. Usually it will work again without an issue. Is this indicate the monitor power adaptor/power supply is failing? My running dual monitor, the 1st monitor, no issue at all. Been using this monitor for 10 years+. It seems like the monitor require "charge up" time in order to boot up without an issue.
The model is LG 23EA53
This is the original adapter, no brick, just the UK 3 pin power adapter. 19v 1.3A. I'm able to source a replacement unit locally at around 7USD.
Update (05/18/2022)
@nick @oldturkey03 The OEM adapter arrived today and I just replaced the new power adapter, the issue goes away immediately. The monitor can boot up immediately without waiting. The syndrome is very similar like the video below, it has a very soft hissing sound coming from the monitor when using the old adapter, the monitor will power up and flash once. After replace with a new adapter, the hissing sound also gone. The OEM adapter only cost around $4 USD. I save myself 100+ bucks without a need to buy a new monitor. Thank you so much for the feedback and help! Below is the new adapter from 3rd party.
Ist dies eine gute Frage?

Did you go through LG or a 3rd party?

@nick 3rd party. Most likely LG will charge a premium for just an adapter.
