How to connect lw etv 01 to a laptop using vga


Most laptops require you to tap the F3 or F4 key to select a display or use both internal and external displays. Likewise, if you have no display when powering your laptop you can tap that same key and get the laptop display back most of the time. The key in question is used to select the laptop display, an external display, or both.

Toshiba m35x starts /stops intermittently with no power to display monitor


By whom Kathleen? You?

I ask because there are two ways to answer this;

1) You performed the procedure, and less for me to post.

2) You did not perform the procedure, and I need to explain from the beginning; using a diagnostic flowchart, pictorial guidance, and guidance from me.

While I wait for your reply, suggest perform this simple test first;
Laptop OFF, monitor OFF, attach an external monitor;

1) VGA monitor to RGB (VGA) port on left side of laptop.
Can use a CRT type of monitor (Looks like a small TV), or flat LCD screen monitor if it has a VGA cable.

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

OR;

2) S-Video port on left side of laptop for TV, or external video display device

http://en.wikipedia.org/wiki/S-Video

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. (Display device)

If not there are 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external monitor
3) External monitor ONLY

Press, and hold the Fn key down, and at the SAME time tap once on the F5 key.
The F5 key is the Display Toggle-Over key.

Still no?
Hold the Fn key down again, and tap once more on the F5 key.

Display on external monitor means there is a problem with;

A) Video Cable
B) screen Inverter
C) LCD screen

Which means if computer display was working correctly before;

1) Whoever repaired it could have used the external display option, and it needs to be set back to internal

2) The Video Cable connections are not tight, not correct.

Loose at motherboard, screen Inverter, or LCD screen.

3) Anti-Static Procedures were NOT followed, and laptop is now an expensive paperweight.

My laptop is vga,so i have bought a vga cable,and a converter box with HDMI cable. My samsung series 5 tv will not pick up the laptop. i have tried all the options available but it just says check devices...


Wouldn't it be NICE to know what laptop you are referring to

Oh well...........maybe one day

By factory default settings the display should automatically show in the external VGA monitor. (TV. Whatever)

HOWEVER;
Your laptop has 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

By factory default settings the display should automatically show in the external VGA monitor. (TV. Whatever)

Press, and hold the Fn key down, and at the same time tap once on the Display Toggle-Over key.
Which key is the Display Toggle-Over key?
Dunno. Laptop manufacturer and model number wasn't stated.

(One of the F keys at the top.
Generally;
Acer = F5
HP = F4
Lenovo/IBM = F10
Dell = F8, unless it's Alienware - F6)

Did that? That's how it worked on your friend's TV?
Then your TV is the problem.
Settings I assume. NOT a TV tech.

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.

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.

Th problem is lcd


No display on laptop's internal monitor, and there is no blinking cursor?
Start with seeing if it is a display problem.

Connect a VGA monitor to the laptop. If the display does not show on the external VGA monitor, the problem is the graphics chipset.

You did not state the model number of the Fujitsu laptop, therefore all I can give is generic basic information.

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

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

The VGA connector (Port) on your laptop is either on the side, or back of the laptop. May be marked on laptop as RGB.

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

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

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

The Display Toggle-Over key is one of the F keys at the top of your keyboard. F1 through F12.
It will have a monitor symbol on it.
(For example most HP laptops use the F4 key )

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

If no display shows on the external VGA monitor you have a bad graphics chipset. Motherboard replacement.

If a display does show on the external VGA monitor, you have a problem with the Video Cable, and/or in the Display Assembly.

Post back with the results, after using an external VGA monitor, in a Comment.

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.
