The monitor HPL1940T refuses to on

Is there a LED light on any part of the screen after you power it on?
1) If there is, try replacing the VGA/DVI cable (cable from PC to monitor). If nothing shows up, it means there is a hardware defect and you will need to send it in for warranty or repair.
2) If there is no LED light to begin with, replace the power cable and try it again.
Still no light - repair/replace it. If LED appears - See Number 1)

Hyundai L19T lcd monitor. Monitor powers up but power indicator light keep blinking and display image just blinking too. What may cause that?

Sounds like you have some bad electrolytic capacitors.
If you are tech savvy, open up the unit and look for capacitors that have bulging tops or leaking electrolyte / bulging at the bottom and replace any/all that look like this.
In most cases, this will fix you right up quick.
It's the right age for this to be the most likely issue.
The capacitors will be near the power input and the inverter stages of the circuitry.

If not a bad kettle lead or loose connection at the monitor it could be:

Failing inverter, also maybe powerboard capacitors leaking or not holding charge. flicking the power switch will cause it to fail more quickly, repair or replacement I'm afraid

Monitor not working, when I plug it in all I get is a quick flash of a couple of colors then nothing. Any suggustions?

That mean your LCD lamp is going bad, replace the lamp or replace the whole LCD.

Monitor won't work

Try adjusting the video connection on the back of the monitor and kinda wiggle it from side to side to see if there's a loose connection. One other thing to check (In case it's a newer LCD) is that the video isn't switched to DVI (It should be automatic, but it can't hurt to take note of this)
