Averatec 3150h monitor problems

Monitor will flicker on and off at times - no always. You can still see the image but it is very faint. Not consistant and can't tell if touching certain areas helps or not. Is this a backlight problem and how can I replace it if it is?

thanks

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 averatec 7100 series laptop powers up, but the screen stays black... what's going on? Tammy


If you can see a faint image on the screen when you shine a light on it at an angle, the backlight on the screen is not working. Either the inverter has gone out or the fluorescent tubes are bad.

My display flickering


1. Check the cables for lose connection in the connectors.
2. Check if there are interferences of magnetic fields from other gadgets.Yes, check if near your laptop, you haven't placed speakers, florescent lights, cell phones, radios and any other electrical device.
3. Check if there were any changes in the display settings like when some computers are upgraded from their original versions. For instance, many laptops that have been upgraded from Windows 95 versions to higher versions, have shown problems of flickering due to poorly calibrated refresh rate.
4. Many a time, it may occur that the pixels on your LCD laptop screen/LCD Monitors are damaged in certain area and so you're unable to see proper images. If that is the case, then you don't have any other choice but to change the entire screen and replace it with a new one.
5.To check if there is no problem in your video card, connect another monitor to your laptop through the VGA port. If it shows any faint images or jumbled images, then the main reason for your laptop flickering screen is your video card.
6. if you don't find that there is any other problem you can detect, there must be problems within your computer monitor screen, otherwise It is advisable to go to your laptop service center and get the laptop checked. If you find that your laptop screen is still in warranty period and you find problems of flickering, it is best to get it changed.

Blank screen


Look very closely at the screen when its on, see if you can see a faint image in which case the ccfl tube in the screen will be dead. Also try the laptop on an external monitor.
Otherwise if you know what your doing, remove the battery, hard drive, optical drive, all but one stick of ram, modem/wireless card and try again. There is a small chance it will be the cpu or motherboard.

My screen flickers


You could have a defective screen - a defective inverter or a CCFL lamp.
To determine if you have a LCD screen or video card problem, read this and follow the instructions.

Defective CCFL backlight, it may have the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display or appear black.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
