Question about Computers & Internet

1 Answer

When i turn on the computer i can hear the computer opening but the monitor does not open, sometimes it flickers then black. I have to play with the power button several times to get the screen to come up. If i leave it too long it also turns off and takes several tries to get the monitor to turn on. Is there a way to fix this or do I need a new monitor?

My lenovo LCD screen is flickering black and striped lines, how to get it fixed in Richmond Hill Ontario


Laptop computers have LCD displays that are sensitive to many things. LCD displays have faults that sometimes produce a flickering screen, lines, dots or a faint display. These screens are sensitive to magnetic fields or electronic items near the computer. Speakers, cell phones, lights and other electrical items are examples. Your display also could be flickering due to software issues such as the video drivers or hardware issues relating to the inverter going bad or the LCD screen itself needing to be replaced. Trace the cause of your problem to come to a resolution.

1.Turn off the computer. Disconnect all external devices. Turn the computer over (bottom facing up). Take out the battery and reseat it. Turn the computer on.
2.Reset your resolution and refresh rate.
Windows XP:
Right click an open area on your desktop. Click "Properties" in the drop-down menu.
Click the "Advanced" button at the bottom of settings tab. Another dialog box appears. Click the "Monitor" tab. Change the Refresh rate to your default, or 60 hertz. Click "OK."
Windows Vista:
Click "Start, Control Panel." Find and click "Appearance and Personalization." Click "Adjust Screen Resolution." Change resolution to the default, or 800 x 600. Click "Advanced Settings." Click the "Monitor" tab. Change the refresh rate to the default, or 60 hertz. Click "OK."
Windows 7:
Click "Start, Control Panel." Find and click "Display" Click "Change display settings" on the left side. Change screen resolution to 800 x 600. Click "Advanced Settings" in the lower right. Click the "Monitor" tab. Change the refresh rate to 60 hertz. Click "OK."
3.Check the computer's surroundings. Move away any speakers, fluorescent lights, fans, cell phones, radios and any other electrical device that can cause flickering. Temporarily move electrical items away from the computer to see if they are producing this issue.
If the flicker stops, put back one item at a time to determine what is causing the problem.
4.Connect an external monitor to your laptop computer to see if that screen is also flickering. If there is no flicker, then the problem is strictly with the laptop, indicating a possible hardware failure. Contact the manufacturer for a replacement LCD.
If the flicker continues, go to next step.
5.Reset/Update your video driver. Click "Start" and right-click "My Computer." Click "Properties." The "System Properties" dialog box will appear.
6.Click "Device Manager." A list of items will appear. Click the (+) sign next to "Display Adapters."
7.Right-click the video adapter and click "Uninstall." Confirm removal. Restart the computer. The video driver will automatically reinstall itself.
8.Check to see if the flicker still exists. If so, go to the manufacturer's website. Download and install the newest video driver and BIOS for the computer.
9.Restart computer once drivers are installed. Continue to the next step if there is still flickering.
10.Open up your display screen all the way. If the flicker stops by opening it a certain distance, it is the display inverter. If the flicker still exists, the LCD screen should be replaced.
11.Contact the manufacturer of the computer for more information and a possible replacement inverter and LCD display. This will depend on the manufacturer and the computer itself.

I hope you find it very helpful. Thanks

My Dell 17 inch monitor keeps dying out. At first, it would flicker black and then go back to the original setting. Now, it flickers black and dies out -- the "on" button goes from green to...


You can verify that it is the inverter going out by turning the monitor on in a dark room and shining a light directly into the screen. If you cannot see anything, then something has happened to the power circuit. Perhaps the solder on the power port has gone bad, and needs to be redone, or part of the circuit board fried. The only way to figure this out is to open it up and take a look-see. If you don't wish to try this, you can always take it to a shop and have them look at it. Be careful opening it, the inverter is high voltage. Don't have any power going to the monitor if you do this.

I have SyncMaster 940nw LCD monitor, which works strangely: screen is often black(sometimes I can see unclear flickering), power indicator is double blinking one time per second. Menu doesn't show up...


The problem is in the inverter board which powers the back lights behind the screen. The cause is bad capacitors that sometimes bulge at the top indicating they are open. The board needs to be changed or an attempt made to repair the old one. Now you indicated a second problem with the menu not coming up, you probably would be further ahead to replace the monitor.

My monitor starts to flicker and sometimes it's so bad it goes black the only way to make it stop is to adjust it up and down or turn it off and back on again


Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas of what goes wrong: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further, it will also help out other people with the same problem.

Shortly after turning on computer the screen flickers and then goes black


Open the monitor, examine the circuit boards. Look for small components that look like small cans, these are capacitors. If you see any that look bulged on top, then your problem can probably be solved by replacing these. Check out the following sites;

Blue light on/off switch to monitor flickers, but will not turn o


Hello,

The problem on your monitor is a bad power supply. Because of heat buildup in LCD monitors2.gif parts called capacitors overheat and blow out. You can go to our web site at:
www.ccl-la.com/badcaps.htm and see what to look for. If you open your monitor and see blown capacitors that look like the pictures on our site then replace the bad ones and you should be back going. Email me if you have additional questions or if you need to get the capacitors, we carry them in stock.

I hope this helps, if so please rate my solution.

I have a fujitsu lifebook N6460 the screen flickers and goes out


Sounds like you back light or LCD inverter is going out, If you don't hear a whine then it is just the LCD screen, if you hear that whine then it is the inverter. An inverter will run 40-60 dolloars as opposed to and LCD screen which usually start around 100 and go up...

Hope this helps, if so please rate my solution accordingly.

Since it seems as though you dont move it very much you might be able to hook an external monitor up to it and using the Fn+F5 button swap it to use the external monitor untill you can get it repaired.
