Question about ViewSonic VA2226w 22" Widescreen LCD Monitor

1 Answer

Monitor flickers or 1/3 turns black, have tried wiggling cable, and moving/tapping monitor, sometime it works great, other times i fight this every few min. Doesn't matter if i turn computer all the way off, or just shut off monitor. seems to have a mind of it's own when it does it.

You may have a faulty inverter or loose power inverter connection. OR
You may have a 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 the monitor up first then the laptop, 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.

Screen has been flickering, does not go black but gets really dark. Sometimes if I tap it or move it is stops. Is my screen going bad?


sounds like a loose connection somewhere. find a local computer repair shop. Often those guys can diagnose a common problem just by glancing at the symptoms. GeekSquad is great but costs lots.

sounds like the LCD cable connection to the motherboard is loose. if you can, refer to the manual to remove and reconnect the LCD cable connection to the motherboard making sure it is securely attached. if this does not work, test if the same display problem will appear to an external monitor once connected to the laptop. if it does, it would be a video card problem and you'll need to get it replaced. if it only happens to the laptop LCD even after reconnecting the cable connection for it, you may need to get it replaced. hope this helps.

Display starts out OK, but after a few minutes it begins to flicker in the upper corners, and the turns on and off a few times before staying black?! Everything else seems to function OK.... BIOS issue???...


please check the monitor or LCD that you have. because the computer will not flicker if there is a problem on the display. isolate it. use other monitor or LCD then check if it flickers again.

Picture flickers in and out


Kinda hard to diagnose with the limited info, but try borrowing a monitor and see if the result is the same. If yes. look at your video card. Bad connection or cable from PC to monitor will do this too. Try removing and reinstalling your video card. Sometimes they have a bad connection to the motherboard.

Screen flickering


Not likely a bad monitor...
The monitor cable on the back of the computer is loose.

Could also be the screen setting that is difficult to achieve and maintain.

If the cable is already tight on both ends, you might try a lower resolution setting for the monitor.

1. Right-click anywhere on the desktop
2. Go to "Properties" on the drop-down menu
3. Select the "Settings" tab
4. Slide the Resolution knob to the left a little (1024x768 or 800x600) and press [OK]

Hope this helps

Dell monitor


Who manufactured it? Better call them to check if the monitor's still under warranty. Im thinking it has to be replaced and may eventually fail completely.

Screen goes black


. if The screen flickers then turns dark,when you move it or tap it lightly on the sides, it may be due to Failed cable at the back of the screen or LCD
In some cases you might hear a buzzing noise coming from the area where the inverter board is located, it’s on the bottom part of the screen Troubleshooting: If the screen is black, look for the “lid closed” switch and try pushing it a few times. It’s usually a small switch near the hinges that is pressed when the lid(the screen) is closed. Sometimes these switches get stuck in the “lid closed” position that results in black screen(no backlight) or non-starting laptop. Also some laptops have a magnetic switch (newer Dells, most Macs, etc.) that doesn’t get stuck.
The most common failures are (in this order): inverter, “lid closed” switch, cable, LCD, backlight.
the display assembly.so open the display assembly check the cable fix it tightly and again if no improvement change the inverter PCB

Hp Laptop screen flicker


Hi, i noticed that when I unplugged my HP the screen stopped flickering. I then re-plugged in the power, when to the Nvidia control settings, to PowerMizer, and changed 'ac outlet' to Maximum Power Saving.

Not the world's greatest solution, but hey, working laptop now.

Cheers,
Andy.

Monitor goes black with a white horizontal line across the middle of the screen


Check to see that the monitor cable is correctly installed. Also, make sure you have the most up-to-date drivers installed for your graphics adaptor card(both ATI and Nvidia carry catch-all driver programs to keep you up to date.) Tighten the cable screws of course, to make sure the monitor cable isnt just wiggling in its seating.
