The monitor screen has gone black. By switching off and then swithing back on a faint image is seen which flikkers and then goes black again.

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.

The fault could be a faulty inverter board that supplies high voltage to the CCFL lamp or the CCFL lamp is faulty. The CCFL lamp is a mini fluro lamp that provides the back lighting for the screen.

Check if this will work on an external monitor, if it will, you can point the finger at the following:

• Inverter failed: If you cannot see any image on the screen even a faint one, replace the inverter
• Backlight gone: if you see a faint image on the screen, the screen needs replacing
• Possible failure (unlikely) of the vga cable

If it will NOT work on an external monitor, the graphics chip on the motherboard has failed.

Hello,
If the screen went black and you can still see faint images of what your computer is currently showing, the typical issue would be a burnt out backlight. For the repair cost, I'd say just invest in a new monitor.
Just to cover the bases, make sure your brightness and contrast settings on the LCD are not set to zero.

how it looks. Is ther any text?

magazine991, Use your warranty first! It's free! The internal "switch-mode-power-supply" has gone into partial shutdown mode. If you couldn't see the faint image on the screen using flashlight 1 inch from screen then it would be in FULL shutdown mode. You must have very good vision!!! Now all you need to do is get into my fixya profile and read, read, read!! Your monitor's basic design and operating principles are NO DIFFERENT than any other brand of CCFL back-lit LCD unit! Find out all your options on what you can do with your now BLACK but not BLANK monitor. Do not rate this response till you want to break this link. Do make a comment for more info if you still don't know what to do. I'm 12fixlouie Bye for now

Can you see a faint image on the screen, if so your back light is failing. If you cant even see a faint image and is flickering then the inverter board is faulty and needs to be changed. You can search the internet by doing a google search for the make and model of your monitor and find spares, there should be some good videos on youtube on how to change the inverter.

Check that the monitor is still receiving a signal it could have gone into standby mode.
If not you either have a faulty inverter or the back light has gone, to test this when your computer is on is to check you can still see a faint image on the screen that means the backlight has gone, if not its the inverter.

If you power it on, take a flashlight and shine it on the lcd at and angle and look real close to see if you can see a faint image. If you can, then your backlight in the screen is not working.
Also, you can attatch an external monitor to it, while its off, then power it on and see if it lights the external monitor. Try that and let me know your results.
If you get a picture ok on the external, and you can see a faint image on the lcd using a flashlight, then it could be the backlight inverter board or the bulb itself inside the lcd went out.
If you don't get any picture at all, using an external monitor and can't see a faint image on the lcd using a flashlight, then I would say there's other problems with the laptop itself. Could be a mainboard problem, power issue, etc..

i hope the problem will be in LOT of the monitor...you need to replace the LOT
