Screen/ video display is dark.

HI there do check all circuit boards in back cover for any blown fuses or other electronic components , If all good then you will have to remove LCD screen to test LED lights . switch TV on from standby mode and shine a LED torch onto screen with room completely dark if ICONS do display ,Then i wood recommend for you start off checking your power supply circuit board or driver board . A easy way of checking if LED lights are working again in a dark room with TV switched on look through back cover vent holes for any light shinning through small openings this would determine if some or all back LED lights are blown.

Your computer screen or monitor may have wiggling images when it is too close to electronic interference, such as a power supply, cell phone, non-shielded speakers, a fan or electric motor.

Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

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.

I have the same TV - I have a dark spot in the upper left hand corner. I have always thought this TV was dark. Be sure to get OME lamp. Cheaper ones are not worth it and can damage your TV more.
dlplampsource,com--Just a note if this ever happens to you. TV would not come on in the AM-Had no picture, but had sound. It was not the lamp, but the safety switch. It's blue and at the bottom of the lamp housing. As soon as I flipped it and replaced the back cover, the TV came on.

Look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the back-light stays off even when you open the LCD screen or turn on the laptop. The switch turns off the back-light when you close the LCD display to save the laptop battery power.

If no luck, try to remove battery and drain the power, then replace battery and turn on.

If that didn't fix it then there are 3 things that could have gone wrong:

1. Video cable connection from inverter to LCD got loose. To check this, follow instructions from step 3 on how to open the LCD and check if cable is fitted properly.

2. The video inverter is faulty
The screen inverter failure is very similar to the back-light lamp failure. In both cases the screen gets very dark and the image on the screen becomes very faint, barely visible under a bright light. If it's still under warranty, take it for a replacement. You can replace this otherwise - you can find the inverter under the screen, follow the procedure described at point 3 to open up the screen.

3. The LCD monitor is faulty
If it works on an external monitor most likely the LCD is faulty and needs replacement. If it's still under warranty, take it for a replacement. If not, you can do it yourself, it's pretty easy. Remove the rubber covers on the side of the screen, unscrew the screws take the plastic cover off, disconnect the video inverter and put in the new LCD after you connect the video inverter to it.

If the laptop acts as it would start and there's just no image, look at the LCD screen very closely and check if you can see a faint image on the screen. It's possible that the LCD lid close switch stuck in the "closed" position and the back-light stays off even when you open the LCD screen or turn on the laptop. The switch turns off the back-light when you close the LCD display to save the laptop battery power.

Please clarify your problem so someone can help you.


1. Does the camera power up? It has good batteries and the Status Indicator LED lights up showing that the camera has adequate battery power?

2. Is the screen blank when playing back previously taken photos also, just during recording, or all the time?

3. Can you see the camera menu's ok but not the live view of the subject.. or is everything blank?

4. Are you quite familiar with the menu's and most aspects of this camera model and you're sure all the settings are correct?

Please provide more detail.
In the meantime check the basics such as:

1. Press the display button on the back while the camera is on. This toggles the display setting between various settings such as Off/ On / Info. The screen may be switched off.

2, Check that the monitor brightness setting is set to medium at least in the menu's.

3. If the problem is only affecting recording then check that the main record settings are correct for the type of scene. For example don't use Beach, Snow, Candle or manual with a super high shutter speed while taking regular daylight shots.

2nd example .....If you set the shutter speed really high such as 1/1000 second while using indoor lighting the shots will be very dark.

4. If the LCD display has a hardware issue you could connect the camera to a TV using the video output jack and look at it that way. Then you'll know if the built-in LCD is ok or not.

5. Having a damaged or stuck video output jack WOULD cause this problem also,, since that circuitry is designed to automatically shut off the built-in LCD display when you connect a video cord to it. So leaving a cord plugged in to the video jack would shut off the display.

There are steps to 'change' the visual effects of the "Display." 1. Right click on "Desktop", click Personalize, click, Display Settings. 2. Identify, Monitor used? 3. Down (arrow) select Monitors' graphics. 4. Adjust, (low>high) resolution. 5. Select, Colors (16 bit>32bit), etc. 6. Click, Advanced Settings, click Properties ("check device status"). 7. Update Drivers (only if, necessary?) 8. Click on "List All Modes" select valid (modes) for the monitor. Note: Always click on the 'Apply', and 'OK' buttons after application changes for the process to take effect. 9. Restart "Computer". *Next go, to: Screen Saver, in the Screen Saver Settings change 'Power' settings. *Next go, to: Start Menu, click on Product Name: (Toshiba), click 'Utilities' click, Toshiba Assist, click 'Optimize' click,"Display"; change power on display. *Next go, to Control Panel, in Mobile PC, click; "Adjust commonly used mobility settings" (changes the following); Display brightness, and Connect Display. “I hope this Fix it!”

dear,
check the flyback. did u hear any noise coming from that ..

Hi, the issue may with the LCD panel. I work in DELL and have been getting lot of issues like this. It's called vertical line defects.. You can connect and external monitor and press Fn and F8 to toggle the display over to the Monitor. If the display is fine, replace the LCD screen. If the system is under wrranty, call Dell tech support and get a replacement or else call 800-288-4410 (out of warranty repair) department to send your laptop for repair. If the display is the same on the monitor, then the video card/Motherboard has to be replaced.

If this information is succesfull, then please rate!!
