ADVUEU EZ18A LCD monitor

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.

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.

Hope this will help... Your response is very much appreciated....

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

Your monitor power supply has several capacitors going bad. You’ll need to have these replaced by a reputable repair person or check my website www.micromendllc.com. Thanks

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.

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.

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.
