This could indicate a problem with the graphics card. Take the card out and clean it, then clean the slot that it fits into. (I normally use a small dry paintbrush).

Replace the card, making sure that you push it down gently but firmly and ensure that the plastic clip has gone back correctly that hold the card in place. Rescrew the card back to the casing correctly and reboot.

Hopefully this will resolve your problem. If it does not, to determine whether or not your graphics card is faulty. Change the monitor lead over to the onboard graphics port instead of the agp/pci port and reboot. If the monitor works properly with no problems, then you have a bad graphics card.

I hope this helps.

your problem sounds like you have bad capacitors on your monitors power board. once you start it, they do not have enough capacitance to give to start the monitor, but after letting it for some 10ish minutes or so, they capacitate enough to start. even then, after some time, they will lose the capacitance because they are feeding the monitor in constant power when the power from the outlet drops a bit, but being bad - they will shut off your monitor. some repair shops can change capacitors only, others would make you change the all power board

Why does my HP vs17 monitor screen keep going to blank black screen like it turned off but did' power button light is still on? Everything is running but no picture.....keeps happening everytime...

this old monitor has 2 issues.
1: it has CCFL tubes that love to burn out (backlamps)
most this old are long go, yell,dim.,blinking or DEAD.
2: push the menu button on front of mon. turn off power saver.

3: if the PC goes to sleep, or hibernete mode (parked)
then that is 100% normal
if you dont like feature then go to windows control panel
click power, ICON and turn off all monitor sleep /hibernate modes.

that assumes windows, no OS stated.

if the lamps are dead,
use flash light pointed to sceen, see data. ? bingo for bad CCFT tubes.

The monitor goes blank after a few min, it comes

Are you sure that your computer isn't just going into power saving mode? Not sure what operating system you have but go into the screen savers tab or video properties and find out how your system is set up for power saving It may be starting before your screen saver does so the monitor would just go black.

Blue power button flashing with blank screen

This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's the problem. You can confirm that it's the monitor and not your computer or the cable by plugging in another monitor if you have one to try.

If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.

Monitor suddenly goes black

Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!
