    My Hp F1903 monitor started going out several months ago. I I cut the power to the monitor it will work for an hour or so before going black. If I reboot it may work for a socond or so. I have to cut the power to it for a day or so before it will work again. I thiink it has to be a capacitor but I am not a guru that can fix such things withou a lot of help.



    Thankyou

    My 180mt blacks out intermittently. Sometimes I can use it for a while, but then the problem pops up again. The light just blinks and the screen is black.

    I have the same problem as already described. The monitor will work for a while, then go black. It was only 1 year old when this started.

    My Fujitsu Siemens monitor blacks out after half a second when I try to reset/ turn it on, it's been doing that for about a month now. If I finally get it working I leave it on overnight and it seems to remain intact as long as I don't reset or shutdown.

Failing Inverter An inverter, typically found inside a laptop computer, consists of a small board, which has impregnated electronic circuits stamped on it. Inverters look like thin boards about the of two sticks of chewing gum. The inverter and its bulb control the intensity of the liquid crystal display, which lights the screen monitor. The computer can control the output voltage of the inverter and either lighten or darken the screen. A special type of inverter can adjust the brightness of the screen by using an internal sensor to judge the room brightness, and then adjust the screen accordingly. Failing inverters give off some specific warning signs, which can be recognized by observing different screen characteristics.

Short Intermittent Display Upon turning on the laptop, the screen flashes on in the normal mode for a short period and then blinks to black. A very faint image appears in a dark background, which will be very hard to see almost invisible. After shutting off the laptop and restarting, the same mode occurs, where the screen appears normal for a few seconds then fades to black. This condition points to a failed inverter. To confirm this, plug in an operational external monitor; if the external monitor functions, the inverter has failed. b> Total Blackout with Ghost image b> The laptop turns on, as indicated by the power supply button, but the screen comes up black. The screen comes up black after restart. You might be able to detect a very dim or ghost-like image on the monitor. When you plug in a known functioning external monitor, the external monitor operates normally. This mode of display indicates a failed inverter. b> Long Term Periodic Operation b> With this failure mode, the laptop screen illuminates normally upon start-up and remains that way after several minutes, hours or even days, until it goes very dark again. Brightness controls or restoration attempts do not work. Most often, the screen will function normally with a computer restart, but will eventually return to black. Faint ghost images might appear, as seen in the total blackout mode. b> Dark With Color Variation b> Upon computer start-up, the monitor shows black or dark gray, accompanied by very faint images. The screen might have an intermittent color change, or remain on with a non-standard color variation, like pink or red. b> Auto Control Switch b> If the screen appears black, with no faint or ghost images, look for the lid switch near the back hinge. The switch, when depressed with a closed lid, shuts off the computer and monitor functions. Sometimes the switch becomes stuck in the closed position, disallowing the computer and monitor to turn on when opened. Pushing the switch manually several times can often free it up. If the switch tab has broken or jammed inside the case, it needs replacing. b> Loose Connection In this mode, the display looks normal upon start-up, but tapping the side case of the computer turns the screen black. More tapping results in the screen functioning normally then cutting out again. This condition points to a loose wire connection from the inverter to the LCD backlight lamp, or the video cable. The connectors can be accessed by removing the monitor bezel screws and pulling the plastic retainer off. Both connectors can be cleaned and refitted.

My HP Monitor refuses to turn on.. It's on but the screen is black


martineillas, Go here first, and do some reading. http://www.lesliewong.us/blog/2005/05/02/hp-pavilion-f1703-flat-panel-display-blackout-solution/ Then do standard flashlight test to determine "full" or "partial" shutdown mode of the internal power supply. Look at rear of monitor for "date of manufacture" ?? If screen is black and blank, then supply is in full shutdown mode. If not blank, only black, then 5vdc ok, 12vdc in shutdown mode (bad) !!! Do some extensive reading in the fixya profiles of the technicians here on FIXYA. Plenty of repair documentation already been written on this type of lcd monitor repair. Always state "model number" and approximate total "on" hours of use when contacting fixya for help. Good luck with repair. 12fixlouie

Black screen


What do you do to make it come back on? Sounds like it might be getting too hot and/or going bad. Try it on another machine and see what it does. Also try another video card because the video card could be going bad.
Sounds like an insurance claim.

WHEN does this problem occur? Does it ONLY happen after the computer loads Windows (or another OS), or does it happen as soon as you turn the monitor on? We really need more information before we can provide specific advice or suggestions... IF this happens as soon as you turn the monitor on, switch it with a different monitor. If the problem goes away, the original monitor is defective, and probably not worth the cost of repairing it. If the problem ONLY happens after you load Windows, boot the system into Safe Mode (press the F8 key during bootup until you see the menu which allows you to select Safe Mode), then reboot and see if the problem has been resolved; simply booting into Safe Mode, then rebooting the system into Windows MIGHT solve this WITHOUT requiring you to change any system settings... IF the problem remains in Windows AFTER you've booted into Safe Mode AND rebooted back to Windows, the videocard driver might be corrupted. In that case, you'll have to reinstall the vidcard driver to correct this problem... If all else fails, it IS possible that the videocard itself is defective; if installing an updated driver doesn't work, try swapping the videocard with a different one. BE SURE to uninstall the OLD videodriver, and install the proper one for the new videocard; if you don't install the correct driver, you could create MORE problems than you have right now...
