I got to vga points connected to the switch(vp211ds)into a LCD but latley the the screen just became blank then come back again my vga cables are not more than 10 meters ,what could be the problem?

Press the Function Button to open the short cut menu. Locate the Input graphic and press the button for it. Each time you press the button, it will cycle between DVI and VGA input jacks. Allow a few seconds for the display to switch inputs. Make sure that cable is connected securely to the associated jack in the back of the monitor and the computer (or other source). If either VGA or DVI input is selected ,but the VGA and DVI cables are not connected, a floating dialog box indicates:

"No Cable Connect" or "No Signal"

Your manual can be viewed here:

Good luck!

Problem can be;

A) Graphics chipset
B) Video Cable
C) screen Inverter
D) LCD screen

Let's diagnose, and find out.

A) Graphics chipset:

To start off with, the Pavilion dv5000 series of Notebook PC's; is NOT known to have a problem with the graphics chipset.
The Pavilion dv2000 series, Pavilion dv6000 series, and Pavilion dv9000 series; does.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port; on the laptop.
The VGA port is on the Left side of the laptop, and located towards the rear.

This is a general example of a VGA connector (port), and VGA Cable,

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

Scroll down a little for VGA Cable example.

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

Turn the monitor on. If a CRT type 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 available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the SAME time tap once on the F4 key.
The F4 key is the Display Toggle-Over key.

Still no? Hold the Fn key down again, and tap once more on the F4 key.

No display on external VGA monitor, suggests a problem with the graphics chipset.
(Most of the time it is a problem with the Mounting, of graphics chipset TO motherboard. If this proves to be your problem, state in a Comment )

Display on external VGA monitor means the problem is the Video Cable, or inside the Display Assembly.
(screen Inverter or LCD screen)

B) Video Cable:

The Video Cable plugs into the motherboard, in an area under the Switch Cover.

(Left side.
Switch Cover is the plastic cover above the Keyboard, and below the LCD screen. Has the Power On Button, LED indicator lights, etc in it)

It then loops by the left Hinge, and goes up into the Display Assembly.
There is a small separate wire that comes from the main Video Cable, and connects to one side of the screen Inverter.
The main part of the Video Cable goes on, to connect to the back of the LCD screen.

Example of Video Cable,

http://www.batterycentury.com/hp-430531-001-cable-p-215726.html

Click on image to enlarge.
The wide connector you see at the top/left, connects to the back of the LCD screen.

The wide connector at the bottom/right, connects to the motherboard.
The single cable (Wire) coming off at the bottom, connects to one side of the screen Inverter.

Just due to normal repeated opening, and closing of the laptop; the Video Cable may become pinched.
This leads to it being pulled on, and may also lead to damage of the Video Cable.
(Stretched/Broken wires)

Procedure is to Physically check the connections of the Video Cable. Visual inspection alone will NOT do. You need to physically see if you can plug the connection in tighter.

1) ALL power removed. Remove the AC adapter (Charger), and Battery.
2) Remove the Switch Cover.

[Switch Cover is just that. A Cover. I will give a link to a free Service Manual from HP Support, towards the bottom of this solution ]

Try to plug the Video Cable connection at motherboard, in tighter.
Once done reinstall the Battery, and attach AC adapter. Plug AC adapter into power.
Turn the laptop on.

Still no? Turn laptop off. (Hold down on Power On button)
Remove ALL power again.

This time check the Video Cable connections at screen Inverter, and back of LCD screen.

The plastic frame in front of the LCD screen is the Display Bezel.
Example,

http://www.ebay.com/itm/447997-001-HP-Pavilion-LCD-Display-Bezel-DV9000-Series-w-Webcam-GENUINE-/170992584210?pt=US_Laptop_Screens_LCD_Panels&hash=item27cff3c612

Service Manual indicates to remove Display Assembly from laptop, in order to remove Display Bezel.
IMHO this = NO.
I think you can remove the Display Bezel, without having to remove the entire Display Assembly.

This video details removing the Display Assembly.
Shows replacing the LCD screen.

http://www.youtube.com/watch?v=NNyvf4KqeIY

What my concern is with removing the Display Bezel, is the integral Hinge Covers that are a part of it.

I believe the Display Assembly can be tilted far enough back, that the Display Bezel can be removed, and carefully ease the Hinge Covers out/off at the same time.

Why not just remove the Display Assembly?
A whole lot less stuff to reconnect, after you have checked the LCD screen connection of the Video Cable, and screen Inverter connection.

After disconnecting the LCD screen from the Hinge Brackets, you just tilt the LCD screen forward, and check the Video Cable connection.
Then slightly tilt the Display Cover back, so the LCD screen can rest against it, and reinstall power.

Connections are plugged in tighter, and this proves to Not be the problem, go on.
(Don't forget to remove ALL power again)

The Screw Covers are made of synthetic rubber, or plastic.
They are held in place by a type of rubber cement.
I like to use a computer pick, (Much safer than a blade!), and lift up at the base of the Screw Cover.

I also like to GENTLY stick them to the Display Bezel for safekeeping. (They like to stick to the tool, your fingers, and it seems passing cars. "Oops, dropped one. Where'd it go? Hmmmm)

If you are careful with them you can reuse them. (Doesn't stick anymore? Apply a TINY dab of rubber cement to them, with a toothpick)

Screws removed, I suggest cut a piece of thick construction paper, that just fits the inside edges of the Display Bezel.
Helps prevent scratching the LCD screen, from your fingernails, when you go to flex the Display Bezel, and remove it

The LCD screen is an Assembly of layers. They are held in the factory aligned position, by the metal Screen Frame which surrounds them.

There are screws that hold the Hinge Brackets TO the Screen Frame, and there are screws which when removed, will take the Screen Frame apart.

ONLY remove the necessary screws which hold the Hinge Brackets, TO the Screen Frame!

Make sure your VGA chord is connected to both TV and Computer. Right click on your desktop and go to screen resolutions. Click on Connect to a Projector and click the Duplicate icon.

I suggest you have a bad LCD screen.

HOWEVER the procedure is to diagnose, and not spend money foolishly.

I need to know the laptop manufacturer name, and model number.
I cannot for the life of me believe FixYa would not ask for this, as a general requirement.

The model number is on the Bottom of the laptop.
Post back in a Comment.

In the meantime,

1) Check the graphics chipset first.
Connect a VGA monitor to the VGA port, on the laptop.
If the VGA monitor shows the same horizontal split of the LCD screen, then your graphics chipset is bad.

Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.
This is an example of a VGA Cable, and VGA connector (Port),

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

Scroll down a little for an example of a VGA Cable.

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

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings the display should show on the external monitor.
IF not;

There are at least 3 display options;
A) Internal monitor of laptop ONLY.
B) Internal monitor of laptop AND external VGA monitor.
C) External VGA monitor ONLY.

Here's where it gets rough, Dawn;
Hold the Fn key down, and at the same time tap once on the Display Toggle-Over key.

What key is that? Dunno. Laptop manufacturer name, and model number wasn't stated.
HP is usually the F4 key.
Acer? F5 key
Lenovo/IBM? F10 key.

The F key at top should have a monitor outline symbol, and an arrow on one side; for the Display Toggle-Over key.
No display on external VGA monitor?
Hold the Fn key down again, and tap once more on the Display Toggle-Over key.

Same display of internal monitor on the external VGA monitor?
Bad graphics chipset. Actually it is probably the MOUNTING of the graphics chipset TO motherboard.
More on that if it is the problem.

Good display on external VGA monitor?
Problem is the Video Cable, or inside the Display Assembly.

2) Video Cable:
The Video Cable connects to the motherboard, (In an area under the Keyboard, or Switch Cover above it), runs under the left Hinge; and up into the Display Assembly.
From there it may have a small cable coming from it, that connects to the screen Inverter.
The main part of the Video Cable then connects to the back of the LCD screen.

CCFL backlighting uses a screen Inverter.
(Cold Cathode Fluorescent Lamp)
LED backlighting May, or May Not.

Due to repeated normal opening, and closing of the laptop; the Video Cable may become pinched.
This can cause pulling on the Video Cable, and loose connections.

It can also cause damage to the tiny wires inside the sheath, of the Video Cable.
(Stretched/Broken)
If you see apparent damage to the sheath of the Video Cable, suspect damage to those wires inside.

Loose connection of Video Cable TO motherboard, or TO screen Inverter, (IF used), or back of LCD screen connection.

The procedure is to remove what components are needed from the laptop, to access the motherboard connector side of the Video Cable; and PHYSICALLY check to see if it is plugged in tightly.

{Components may only be the Switch Cover.
Above Keyboard, and below LCD screen. Has the Power On button, indicator LED lights, and perhaps speakers.

May be the Switch Cover AND Keyboard.
May be the Switch Cover, Keyboard, and Palm Rest Cover; in order to access the motherboard connector of the Video Cable }

Disconnect the LCD screen from the Display Cover, to access the LCD screen side connection, of the Video Cable.

Once all connections are proved to be tight, try the laptop again without fully reassembling. See if you can connect everything, with the LCD screen sitting out a little. Perhaps the Switch Cover off, but wires connected.

HOWEVER of you see apparent damage to the sheath of the Video Cable, or if you don't; the Video Cable MUST be ruled out before going on.

Connections tight? Didn't repair the problem? Remove the Video Cable.
A continuity test of the Video Cable must be performed, with a multimeter set to OHM's.
EVERY wire in the Video Cable must be checked for continuity.

Also an assistant is needed to gently wiggle the cable in the middle, and see if you get an intermittent reading on the multimeter.
If so this indicates a broken wire inside the Video Cable.
Replace.

Not everyone has a multimeter laying around.
Suggest take the Video Cable to the nearest small computer shop, and have the resident tech check it for continuity.
Should only be a couple of bucks.
(They say they can't check it? GET OUTTA THERE!
That ain't no REAL tech! Lol!)

Video Cable checks out?
Then the next component to check is the screen Inverter, again IF used.
Problem is to check a screen Inverter requires a sensitive multimeter.
Read fairly expensive,

http://www.fonerbooks.com/test.htm

For the above reason; the ease of access to replace, (Just remove Display Bezel), and usually low cost; the screen Inverter is usually just replaced. Average cost is around $20, or less.

Screen Inverter isn't used? Problem is LCD screen.
Screen Inverter replacement didn't repair the problem?
Problem is LCD screen.

I know the above may look like, "Wah, wah, wah", from Charlie Brown. (That's what my niece tells me)

If I had the manufacturer name, and model number, I may be able to give you a link to a Service Manual, and possibly pictorial, or video guides; PLUS step by step info from me.

Makes it less, "Wah, wah, wah", lol!

Dell Inspiron 1420 Notebook PC?

The white screen can be fixed. How?

Connect a VGA monitor to the laptop. Connect to the VGA port on the right rear. Example of a VGA Cable, and VGA connector,

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

You can use a CRT type monitor, (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.
By default the display should show on the external VGA monitor.

No?
Press, and hold the Fn key down, and at the same time tap the F8 key ONCE.
Still no?
There are at least 3 display options available;

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

Hold the Fn key down again, and tap once more on the F8 key.

No display on the external VGA monitor, means you have a bad graphics chipset. Replace motherboard.
Display does show on the external VGA monitor, means you have a problem with;

1) Video Cable
or
2) Screen Inverter
or
3) LCD screen

Video Cable:
The Display Panel Cable (Video Cable for Dell), connects to the motherboard by the left Hinge.
Goes under the left Hinge, and up into the Display Assembly.
It then connects to the Screen Inverter, and to the back of the Display Panel. (LCD screen for Dell)

From normal opening, and closing of the laptop, the Display Panel Cable may become pinched in the left Hinge.
This can cause;
A) The connection at the motherboard to come loose
B) The connection at the back of the Display Panel to come loose
C) Stretch the wires inside the Display Panel Cable's sheath, and damage the wires. (Break)

If you are lucky just the connection at the motherboard, and/or connection at the back of the Display panel, may have come loose.

Diagnoses is to NOT just look at the connections, but physically push the connectors of the Display Panel Cable, into the connector at the motherboard, AND back of the Display Panel.

Visually inspect the Display Panel Cable's sheath. Do you see any outward appearance of damage? This means the tiny wires inside may be damaged.
Replace the Display Panel Cable.

Remove ALL power. Remove the AC adapter (Charger), and Battery.
Remove the Keyboard Cover.

Unfasten the Keyboard, LEAVING the Keyboard Cable ATTACHED to the motherboard. Roll the Keyboard over, and lay it upside down on the Palm Rest Cover,

http://support.dell.com/support/edocs/systems/ins1420/en/SM/display.htm#wp1129771

[ NOTE*
Two Philips head screws at top of Keyboard. After removing, lift the top of the Keyboard up a little, slide it a LITTLE towards the Display Panel.
DO NOT lift it straight up at first.
There are 3 plastic tabs on the bottom of the Keyboard, that slide into the Palm Rest Cover. If you pick it straight up you will break those tabs off ]

In Removing the Display Assembly, note where number 1 points to.
This is the Display Panel Cable's connection, TO the motherboard.

Note where number 2 points to. Those cables going to the Mini-Card Antenna, HAVE to be reconnected, right back to the SAME terminals on the Mini-Card. Make a mark on the cables, and matching marks on the Mini-Card.

Use the instructions in Removing the Display Bezel.
Use the instructions in Removing the Display Panel.

View the last illustration in Removing the Display Panel.
Note how the Display Panel Cable attaches to the Display Panel, and Screen Inverter

Number 2 points to the connection at the back of the Display Panel
Number 6 points to the connection to the Screen Inverter
The Black connector that is not numbered at the bottom, is the motherboard connector of the Display Panel Cable.

This is a better view of the screen Inverter,

http://www.ebay.com/itm/Dell-Inspiron-1420-1421-LCD-Inverter-Backlight-Combo-/370274752470

Display Panel Cable checks out? Look at the screen Inverter. This small circuit board is located at the bottom of the Display Panel, and behind the Display Bezel. Closer look at link listed above.

Is the cable coming from the Display Panel Cable, plugged in tightly to it?
Does the screen Inverter look damaged?

Post back in a Comment, and we will go from there.

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp. Please click on this link and follow myinstructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

Problem with;

1) Video cable:

A) Video cable connection on motherboard side is loose, and/or on back of LCD screen.

B) Video cable is damaged.

2) screen Inverter:

screen Inverter is bad.

3) LCD screen:

LCD screen is bad.

4) Graphics chipset:

Graphics chipset is bad.

Suggest you connect a VGA monitor to the VGA port (Connector) on your laptop.
See if the problem is the graphics chipset, Or video cable, Or display assembly.

You didn't state what manufacturer and Model Number of laptop this is.
All I can do is state generic information.

This is an example of a VGA Cable, and VGA connector,

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

The VGA connector will be on the side, or back of your laptop.
For the VGA monitor you can use a CRT type monitor, (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.

Laptop OFF, monitor OFF, connect the external VGA monitor to the laptop.
Turn the monitor on. If a CRT type allow it to warm up.

Turn the laptop on.
By default the display should show on the external VGA monitor.
IF not;

There are at least 3 display options.
1) Laptop internal monitor ONLY
2) Laptop internal monitor AND external VGA monitor
3) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the same time tap once on the Display Toggle-Over key.
(For an example HP's usually use the F4 key for a Display Toggle-Over key)

Display shows the same on the external VGA monitor?
You have a bad graphics chipset.

[ Some laptops have been erroneously stated as having a graphics card, when in fact they do not.
The GPU (Graphics Processing Unit) is soldered directly to the motherboard.
This is Integrated Graphics.

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

There is no changeable, replaceable graphics card. Therefore the solution is motherboard replacement ]

IF, the display is good on the external monitor, you have a problem with the Video Cable, and/or in the Display Assembly.

After diagnosing with an external VGA monitor, post back in a Comment.
Also post the manufacturer name, and model number of the laptop.

that switches r made basically changing dvi to vga r vga dvi,if that switches r malfunctionig display goes to blank that means if u connect vga system will have dvi

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

I was getting the same problem with my lcd tv. I was using a DVI to hdmi cable to connect the pc to the tv. I switched to a vga cable and I was able to finally get into the game. Once you get into the game make sure you change all the video settings to be compatible with your tv i.e. resolution for a 720p set should be 1366x768 on the game resolution, and you should also change the refresh rate to 60hz in the game if that is the max. on your tv.

Once you do this, you can then put your hdmi cable back in and get into the game. Every game I install I have to first run using the vga cable, and then switch to HDMI.
