    Thank you for the visual help.I do have PCI card, since my computer is 5,6 years old.Compaq Presario 7000 series to be precise.I went to Best buy to buy the card, it ran around $99 but I did not want to buy the card which was as expensive for old pc of mine and plus I wanted to make sure that PCI card was the problem in fact.They( Best buy staff) suggested that I should bring the pc in and they will run a diagnostics without any charge.I can then buy a card from where ever I want.I want your input as to where I can buy a card on line, what do I look for in the card(specifications for minimum requirements) and not as expensive.

Sorry friend i ws lill busy so could not rply.
Anyways

  • This is the VGA out: monitor not working - ebc4b94.jpg
  • And this is the connection for VGA comes from monitor: c99e5d1.jpg
  • Now if your VGA - Out is mounted on your motherboard then you have on-board VGA card.
  • If it VGA - Out comes from a PCI card like dffb048.jpg
  • means you have PCI VGA card.
Now if you want to use another PCI card just remove the one which you are using and use another one. Use only one PCI card for VGA, need not to use more than PCI VGA card at a time.

Thanks
Iqbal

Laptop all whit screen


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?

My laptop screen is not coming on it is receiving power but still not coming on


Timothy, post the laptop manufacturer, and the laptop's model number. It's on the bottom of the laptop, Usually in a sticker, or white Service Tag.
This way I can guide you in more detail. Post back in a Comment.

A) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA connector, on the laptop.

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

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

Could be on one of the sides of the laptop, or the back of the laptop.
You can use a CRT monitor, (Looks like a small TV), or a flat LCD screen monitor, that has a VGA cable attached.

B) 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 three 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 Display Toggle-Over key.
Which one is it? Dunno. You didn't state what laptop manufacturer, and model number.

It is one of the F1 through F12 keys. Most of the time the F4, or F5, or F7 key. Has a monitor symbol on it, and sometimes a side arrow.

No display on external monitor still?
Hold the Fn key down again, and at the same time tap once more on the Display Toggle-Over key.

If the display still does not show on the external VGA monitor, you have a bad graphics chipset on the motherboard. Usually means motherboard replacement.
(There are problems with HP Pavilion dv2000 series, Pavilion dv6000 series, and Pavilion dv9000 series, in this area. There are other model series of laptops also, not just HP. There is a solution besides motherboard replacement)

C) IF, the display shows on the external VGA monitor, you have a problem with the Video Cable, or inside the Display Assembly.

I can help you find it, just need the laptop manufacturer name, and Model Number.

Yes.

1) Laptop OFF, monitor OFF.
Connect a VGA monitor to the VGA port, on the back of the laptop.

The VGA port is on the right side, as you view the back of the laptop.
This is a basic example of a VGA cable, and a VGA port, (Connector),

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

NOTE* Color does Not matter.

You can use a CRT 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 default the display should show on the external VGA monitor.

IF not;
Press, and hold down on the Fn key, and at the same time tap once on the F3 key.

No?
There are at least 3 display options;

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, and tap again on the F3 key.

(The Fn key is down at the bottom LEFT corner of the Keyboard.
The F3 key is at the top of the Keyboard.
The F3 key is the Display Toggle-Over key )

Screen blank with white dot


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.

Howdo i connect my laptop to my flat screen


Be nice if you listed the Model Number of the Toshiba laptop.
I could post concise exacting information. Without it, all I can do is post generic info. (Bottom of laptop in white Service Tag, or sticker)

On the back, or one of the sides of the laptop, is a VGA connector.
(RGB monitor may be stated)

Example of a VGA cable, and a VGA connector,

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

(May not be blue in color)

The external monitor (VGA monitor), can be a CRT monitor that looks like a small TV, or a flat screen monitor that has a VGA cable.

Laptop OFF, monitor OFF, plug the external monitor into the VGA port on the laptop.
Turn the monitor on. IF a CRT monitor allow it to warm up for a few minutes.

Turn the laptop on. By default the external monitor should graphics.
If not, press, and hold down on the Fn key, and at the same time, tap once on the external display toggle-over key.

The Display Toggle-Over key, is one of the Function keys at the top of the keyboard.
Different models use different keys, so there is no way to state just one.

Some examples are F3, or F4, or F7.

The F key will have a symbol of a monitor on it. Looks like an empty rectangle with rounded corners. May have an Arrow on one side.
Look at the User Guide, or go to Toshiba Support, or state the Model Number in a Comment, to find out what particular F key is the display toggle-over key.

You may have to hold down on the Fn key, and tap the display toggle-over key more than once.
There are least these three options allowed;

1) Internal display of laptop ONLY
2) Internal AND external display
3) External display ONLY
