How do i fix white screen on my kav60 acer aspire one


The KAV60 is also the AOD250.

Netbook OFF, monitor OFF, connect an external monitor to the netbook's VGA port.

[You can use a VGA monitor. Looks like a small TV.
This is an example of a VGA port,

VGA connector Wikipedia the free encyclopedia



Note* VGA port doesn't have to be blue in color ]


Turn the monitor on. Turn the netbook on.
If there is no image shown on the external VGA monitor, press and hold down on the Fn key, and at the same time tap once on the Display Toggle-Over key.
(The F5 key is the Display Toggle-Over key)

No image on external VGA monitor?
Hold the Fn key down once more, and tap again on the F5 key.

Still no?
Problem is internal in netbook. Probably graphics chipset soldered to the motherboard.
Replace motherboard.

Image shows on external monitor?
Problem is with Video Cable or laptop LCD screen.
MOST of the time it's the Video Cable.

The Video Cable connects to the motherboard, in an area under the Keyboard. It then routes up under the left Hinge, and into the Display Panel.
Inside the Display Panel it then connects to the LCD screen.

With frequent opening and closing of the netbook, the Video Cable can be pulled on. This can cause damage to the Video Cable.
(Stretched/broken wires inside the sheath of the cable)

And/or it can cause the connection at the motherboard to be loose, and/or at the LCD screen.

Example of Acer Aspire One video cable,

For ACER Aspire One D250 LCD Screen Cable DC02000SB10 KAV60 New

You can remove the Video Cable, and check it's continuity with a multimeter, or if the cost is reasonable to you simply replace it.

8 to 10 dollar video cable is not the problem? Then problem is the LCD screen itself.

My money is on a loose video cable connection, or damaged video cable.

For additional questions or to have me clarify/simplify anything in my solution, please post in a Comment.

What is vga/dvi cables


VGA and DVI is in the way the video signals travel. VGA connectors and cables carry analog signals while DVI can carry both analog and digital. DVI is newer and offers better, sharper display compared to VGA. You can easily tell them apart because VGA connectors (and ports) are blue while DVI connectors are white.

When I turn on my HP Pavilion 1x1000 It stays on ,but there is no image on the screen, and stays on please help.


A) Post THE Product Number on the bottom of the laptop. It's in the white Service Tag. P/N = Product Number.

B) On the left/bottom side of the LCD screen frame (Display Bezel), there is a switch. Looks like a small button.

This is the Internal Display Switch. (May not be in this exact position for your model. Look around on the Display Bezel, that surrounds the LCD screen)

When the laptop is closed, the switch turns off the display, (Image on screen), with the computer still on.
Tap it a couple of times lightly, with the eraser on the end of a number 2 pencil.

See if anything happens. That switch may be bad.

C) Laptop off, monitor off, connect a VGA monitor to the VGA port on the laptop.

Example of a VGA cable, and VGA connector, (Port),

http://en.wikipedia.org/wiki/VGA_connector

You can use a CRT monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

C) Turn the monitor on. If a CRT type of monitor allow it to warm up.
Turn the laptop on.

By factory default settings, the display should show on the external VGA monitor.

IF not;
There are at least 3 display options,

1) Internal monitor of laptop ONLY
2) Internal monitor AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold down on the Fn key. At the same time tap once on the Display Toggle-Over key.

Don't know what exact HP laptop you have. For most HP's it is the F2 key, or the F4 key, that is the Display Toggle-Over key.
(Key has an empty rectangle on it, with a vertical line on each side)

Still no display on the external VGA monitor?
Hold the Fn key down again. (Bottom left of Keyboard)
Tap once more on the Display Toggle-Over key

NO display on the external VGA monitor, means you have a bad graphics chipset.

(By using an external VGA monitor, you are bypassing the Internal Display Switch, and the Display Assembly. (Internal monitor of laptop)

If you have a display on the external VGA monitor, you have a problem with;

1) Video Cable, (Display Panel Cable for HP)
or
2) Display Assembly

Post back with your results, and if you have a display on the external VGA monitor, we will go on.

If you do not have a display on the external VGA monitor, you are looking at motherboard replacement.

Post back in a Comment.

Turn on my computer, I can hear the fans, no beep noise upon starting. Screen says no signal found. I tried other monitor cables and monitor. No dice.


one of 2 things is happening a) if you have changed the cord and tried other moniters then the display port beit vga or dvi on you computer is broken you will either if you have agraphics card already installed then replace that but if you have no dedicated grapichs card you need to replace the mother bord
B) check your moniter to see if there is a source button if there is then push it to see if the image comes up repeat up to 3 times
ps: if you have a dedicated graphics card look at the back of you computer and if there are 2 different display ports be it dvi or vga (google image the terms "vga port" and "dvi port" to see what they look like) then plug it into the other on to see if the graphics card is broken

Dvi-dvi connection to a ati radeon hd4670 does not recognise monitor,ie no display. Using a supplied adapter dvi-vga and a vga cable their ia screen display but in device manager it is a generic monitor?


Was there an installation disc that came with it in the package? Some monitors require software to be used. If you don't have the installation disc, you will most likely find the necessary software on the manufacturer's support site: ProLite Support Driver Download Site.

If the monitor software doesn't solve the problem, try using a different DVI cable. More often than not, these types of problems can be traced back to a faulty cable or port. If the DVI port on the monitor is bad, you will have to use the VGA port as you are now or replace the monitor.

If the DVI port on the video card is bad, you will need to replace it. A good way to test this is if you have another monitor with an available DVI port you can connect to the video card.

Hope this helps! Good luck!
