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.

Troubleshooting Flat Panel Monitor issues. Screen is blank and power indicator...


Troubleshooting Flat Panel Monitor issues.

Screen is blank and power indicator is off

The monitor is possibly not receiving power. Perform the following steps to fix the problem:
  1. Ensure that the electrical outlet and the monitor are both switched on.
  2. Check that the power cord is firmly plugged into the electrical outlet and the power supply unit.
  3. If the power cord has a removable fuse, replace it.
  4. Try another power cord.
  5. Try another electrical outlet.
  6. Check the power connection at the back of the panel.
Screen is blank and power indicator is steady green

Brightness and Contrast may be too low. Adjust the brightness and contrast using the On-screen display controls (OSD) by selecting the button
Screen is blank and power indicator is steady amber

The monitor is in the Power Management Standby state. The power management feature is invoked when the computer recognizes that you have not used your mouse or keyboard for a user-definable period. Perform the following steps to bring monitor out of the power management state:
  1. Press any key on the keyboard or move the mouse to restore operation.
  2. Check the Power Management software on your computer.
  3. flatpnlmont12.jpgPress the (OK) key to switch between analog and digital mode. If the panel is the wrong mode for the signal being provided, the monitor appears to go into sleep mode.
Screen is blank and power indicator is flashing green
Display mode of the computer is outside the range of the monitor. The display mode the monitor uses is controlled by your computer. Therefore, you should refer to your computer's documentation for details on how to change display modes.

The image size, position and shape may change when the display mode changes. This is normal and the image can be readjusted using the IMAGE SETUP and the monitor controls.

Note: Unlike CRT monitors, which requires a high refresh rate to minimize flicker, TFT technology is inherently flicker-free. If possible, configure your computer for 1600 x 1200 addressability at 60Hz vertical refresh rate.

Use the following table as a guideline and reconfigure your computer to use a supported display mode. The highest resolution (for example, 1600 x 1200) produces the optimal output, but limitations of your monitor may prohibit this setting. Adjust the addressability mode until an image appears.

CHECK SIGNAL CABLE" message is shown and power indicator is steady amber.

The monitor is not receiving a video signal. Perform the following steps to fix the problem:
  1. Check that the signal cable is firmly connected to your computer
  2. Check that no pins are bent in the signal cable connector.
There are noises in the video signal. The IMAGE SETUP function is used to adjust the level of noise in the video signal which causes horizontal lines or areas where the image appears to be unstable and jitters or shimmers. This can be done automatically or manually.
Note: It is not applicable to digital input.
Use the image setup fix the problem:
  1. flatpnlmont6.jpgSelect (Image Setup) menu in the OSD.

  2. Select Manual to adjust CLOCK/PHASE settings.
Image appears to be discolored

The color setting may be incorrect. Perform the following steps to adjust the color settings:
  1. flatpnlmont8.jpgSelect (Image Properties) from the OSD menu.
  2. flatpnlmont9.jpgSelect (Color Properties) to adjust the color mode you find most comfortable or fine tune the colors using the Custom menu.
A few dots are missing, discolored, or inappropriately lighted

A small number missing, discolored, or lighted dots may be present on the screen, which is an intrinsic characteristic of the TFT LCD technology and is not an LCD defect.
Using On-Screen display (OSD) controls
flatpnlmont12.jpgThe settings adjustable with the user controls are viewed through the OSD. Press the (OK) button to display the main OSD menu.
OSD main menu:

Note: The LCD monitor needs time to become thermally stable the first time you turn it on each day. Thus, to achieve more accurate adjustments for parameters, allow the LCD monitor to warm up (be on) for 15 minutes before making any screen adjustments

Vertical strip of flashing horizontal lines on Acer Aspire 7551G screen


More than likely it's the lcd screen and will have to be replaced. I could be the video card, but most likely the lcd screen especially when you can put pressure on the screen and cause changes. To isolate the problem try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the laptop. If the Borrowed monitor displays ok, then the problem is with your lcd screen and the video card is ok. If the Borrowed monitor displays the same as your lcd screen then the problem is with your video card inside the computer.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

Once you narrow it down to the lcd screen as being the problem you might try taking the lcd screen apart to reseat the lcd cable on the back at the top of the lcd. Just unplug it and plug it back into the connector. You can also try doing the same where the lcd cable plugs into the motherboard. Just pull it out and put it back.

My monitor is not responding. I have a blank screen and my power led is flashing green, none of the front monitor buttons are responding, not even to turn of power. Cannot access menu as I have blank,...


Hi Cat, You can try removing the data cable of your monitor, the one connecting to the back of the tower/computer. If there are no issues on the monitor, normally you will be getting the power self test which is indicated by three vertical colors on the screen (Red, BLue, Green). If you dont see the power self test, it may be a problem with the monitor. YOu may want to try using a different monitor to isolate issue if available

Two Advueu flat screen monitors need service every 6 months or so


I have never owned one but when you list out monitors with the same specs Advueu always comes up as one of the least expensive.

Although there are exceptions, the lower price will almost always indicate a lack of quality. Given your experience it is safe to say that your monitor is no exception to this rule.

I have had excellent luck with the following LCD manufacturers: Samsung, LG, Dell, HP/Compaq, IBM, NEC and Mitsubishi.

IMHO: The best vendors are NewEgg.com, TigerDirect.com and the Dell Outlet. Online prices are way lower than store prices.

I have a red vertical line on my dell inspiron laptop.How do I remove it?,please


Try connecting an external monitor to the Dell Inspiron 9300and see if the vertical line is also present on the monitor. If themonitor display is fine, then your laptop’s LCD display panel isdefective. If the monitor also displays the vertical line, then yourproblem is with either the video card or motherboard located insideyour laptop.
-------------------------------------------------------

Another answer:

run the PSA diagnostics. to do so, press and holdany non-keyboard button( like the internet hotkey or access directbutton or even the speaker mute button) and then press the power buttonand power up your system. if your inspiron doesn't have a non-kbbutton, then press the <fn> key.
release both the buttons and the diagnostics begin to run.after thediags finish. if the monitor is working fine, it'll simply say"passed". however, if it fails it would emit a few beep codes.carefully check those beep codes:
1.) if you get a 3-3-3 or a 3-3-4 error beeps, then we use the LCDbuilt in self-test (BIST). boot to PSA diagnostics again. Watch thescreen and listen for the color bar test prompt tones emitted by thePSA Diagnostics. Press <N> or wait approximately 30 seconds tofail the color bar test. The system will emit a 3-3-3 or 3-3-4 PSAerror after failing the color bar test. Wait for two iterations of thefailure code then press <Y>.
Watch for the BIST color generation and listen for the single beeps that indicate LCD BIST is running.
NOTE: Patterns of flashing color should appear on the screen. Withevery color change, an audible beep will be heard. If the patterns ofcolor do not appear, and the beeps are audible, an LCD failure may bethe issue. If the patterns of color appear, a video card or motherboardfailure may be the issue.

2.)if you get an error code apart from 3-3-3 or 3-3-4 :Ensure thesystem is powered off. Press and hold the <Fn> key and press thepower button to power the system on. Release both buttons.
The PSA diagnostics sequence begins. Make note of any alert tones or error messages.
error codes:
123- memory fails
141,142,143,144,145,146 hard drive error
147- IDE optical drive fails
148 optical drive built in test fails
122-memory test initialization test failure
111- fatal diagnostics exception.

i really hope you dont get any of these. these will help you determine,if you need to change the LCD. when you call dell, they will run youthrough these steps anyways. so if you finish them beforehand, you wontpay much to talk to them. cheerio then.

Dark Grey Vertical Bar


1. try connecting laptop to an external monitor and check if this vertical dark gray bar appears. if yes it means video is the problem. you need to boot in safe mode then uninstall the video driver. boot to notmal mode then download and install the latest video driver. if still same problem then replace video card. if video is built in with motherboard you need to replace motherboard.

2. when the vertical dark gray bar did not appear in the external monitor then it means issue is with the LCD panel. Do this turn off laptop. press and hold D key then press Power button at the same time or Press and hold on the Fn key then Power button check if the test will run. Color displays full screen when you keep pressing on N key when the colors appears check the vertical dark gray bar if still exist in the test, this means LCD panel and LCD cable needs to be replaced.
