My screen only displays after 4 /5 hrs

My screen remains dark and blank after the computer has been switched on for at least , 4/ 5 hours, then lights up and works perfectly. If I dont use the computer for half an hour, the screen goes to sleep and wont switch back on for about 20 minutes. Please can someone helpme. Is there something I should know?

    I will try to get another computer to test it. if the monitor is broken, what part of it is broken since it works perfectly when it does come on? Thanks for your interest, I am beside myself since there isn't any support where I live in South Africa, Its a Mag innovision Model 780, Made in China, and no one knows it , not even Mag Innovision.com!!! Don't know where it was bought. Thanks Again, Bev Barrett

Try a different screensaver.

Also look in the display properties by simply right clicking the desktop and clicking properties.

Then locate power management.

the initial seems to be a bad screensaver judging by the 20 minutes, but the 4-5 hours seems to be a sleep mode that bypasses the screensaver issue.

The part that supplies the power to the screen is gone. I recall is is called the 'exciter'. They can be replaced, so take it to a computer repair shop. Same thing happened to my Toshiba.

Monitor goes blank less than a second after turning on.


Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

hello

shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

Has a Toshiba Tecra 9000 won't power up. Power light on front is blanking which appears to be a code 3-3-2


The problem is cause due to one of the following: the backlight or the display, check your monitor brightness settings. Sometimes your brightness may accidentally have been all the way turned down, resulting in a blank/dark screen. The monitor controls are on the keyboard, directly above the numeric keys.
Look closely at your laptop's screen if the steps do not restore power to it and if it remains blank. Can you see a faint image on the screen? If so, the backlight may be off due to the LCD "lid close" detector malfunctioning. This malfunction likely happened due to the lid close switch being stuck in the "closed" position even though the lid is open. The switch is located beside the LCD's screen hinges, and tapping the switch a few times should unstick it.
Use an S-Video cable and plug your laptop up to an external monitor, such as your television set. With the laptop and TV hooked up, turn both on and see if your computer's desktop is displayed on the TV. You can also use a fifteen ( 15 )pin monitor desktop monitor by connecting it to the blue fifteen ( 15 ) connector at the side of the laptop if you cannot see anything on screen it is the display problem. If it is, your laptop's display needs to be replaced. If not, your motherboard and/or video subsystem may need to be completely removed and replaced.

My hp vs19e monitor has dark screen and blinking power button.


Could be the power module or the backlights (more likely backlights if the "luminance" varies)- $156 sounds a little high but not insane, but you realize cost of replacement is lower, do you not?

Blank Screen - No Display though computer power light remains switched on.


You people are not explaining in detail what is actually wrong?.  If you do this we can try to help you.

 

1 Does the power lights light up.

2 Does the hard-drive light light up

3. Does anything go on the computer.

4 What does and what does not (lightup)

 

Just because you have a blank screen does not necessarily mean the screen is "had it" and by plugging an external monitor to see if there is problem does not exist.

For all we know your motherboard may have ceased to exist or your hard drive crashed or your memory chip.  Please help me to help you?
