Can't get picture back on lap top after connecting to ext monitor

Used Nvidia to utilize External Monitor, Now Ican't get anything on my lap top screen, I'm SCREWED! It only has theoption of the 2207 Hp monitor when you look for displays... Don't knowwhat else to do. Originally it had the option of HP2207 + lap topdisplay, clone, or one or the other, that's how I got it that way inthe beginning! The fn F4 hot keys wouldn't work, that's why I went intothe nvidia setting (with guidance from the Hp support people)... nowthey won't help me get it back, because I'm out of warrantee. If I canget it back I'll set it up to clone so I don't run into this problemagain.

p.s. he had me download the most recent of all the drivers (I have the GeForce 7600 something Nvidia. Any suggestions would be GREAT! As well someone said to unhook the monitor, hold down the power button on the lap top and them turn it back on.. no go, no change..

the Lap top is a Hp Pavillion 9000dv Entertainment Center Edition

Hello there. You sound very frustrated. try this, go into your BIOS settings and cycle the settings for your vga adapter, or even reseting the options to basic performance. also, you could hook up the external monitor and disable it while it's hooked up. that should fix any problems with that(if you still have an extra.)

How do you fix a white screen for a dell Inspiron 1100 lap top?


White LCD screen in a Dell Inspiron 1100 Notebook PC?

1) Loose connection of the video cable TO the LCD screen, and/or loose connection of the video cable TO the motherboard.

2) Bad LCD screen

3) Bad motherboard. (More specifically a bad graphics chipset)

To start the diagnoses to find out what the problem is, you will require an external monitor.

This monitor can be a CRT monitor (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.
(A CRT monitor is a VGA monitor also)

Example of a VGA cable, and a VGA port, (Connector on computer),

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

The VGA port is on the back of an Inspiron 1100 Notebook PC.
It is Blue in color.

A) Laptop OFF, monitor OFF. Connect the VGA cable of the external monitor, to the laptop's VGA connector (Port)

B) Turn the external monitor on. If a CRT style allow it warm up.
Turn the laptop on.

By default, (Factory setting), the external monitor should show the graphics of the laptop.

IF Not;
There are 3 options available,

1) Internal monitor of the laptop - ONLY
2) Internal monitor of the laptop, AND external monitor
3) External monitor - ONLY

If there is NO display on the external monitor, (Display; To include a white screen);

A) Press the Fn key, and hold it down. Now tap the F8 key. (F8,CRT/LCD)

Still no display on the external monitor? Press, and hold down on the Fn key, and tap the F8 key again.

IF, the external monitor shows a white screen, Stop.
You have a bad graphics chipset. Option is to replace the motherboard.

IF, the external monitor shows graphics just fine, diagnose further.

A) Look to see if the Video cable is plugged in tightly to the motherboard, AND connected tightly to the LCD screen.

Dell Support > Inspiron 1100 Notebook PC > Service Manual,

http://support.dell.com/support/edocs/systems/ins5100/en/sm/index.htm

Click on - Display
Under the heading - Display Assembly, look at the partial 'photo' under the number 8.

On the left side where it shows two Philips head screws removed, is the Video Cable. Pinkish wire wrapped around a Light Blue wire.
Look at Number 9.
The display-feed flex cable is the Video Cable.

Make sure it is plugged in tightly to the motherboard.

Now go down to Number 10.
In the exploded drawing the number 7 points to the Video Cable.
(display-feed flex cable)

Shows the Video Cable disconnected from the motherboard, and going up to the back of the LCD screen.

Scroll down to the heading - Display Panel. This shows the connection of the Video Cable to the LCD screen.

Also;
The Video Cable runs through the left Hinge Cover.
Repeated opening, and closing of the laptop, may have damaged the Video Cable.

Observe the sheath of the Video Cable. (Outside wrap)
Does it appear damaged? Pinched? Torn?
Even if it does not, I suggest performing a continuity test with a multimeter.

Multimeter's function knob is set to Ohm's. (Omega symbol)
Positive probe lead (Red) is touched to one end of a wire going through the Video Cable.
Negative probe lead (Black) is touched to the other end of the wire.

Do not be concerned at this time with the Ohmage. Concern is to see if ANY reading comes up, not how much.

Perform a continuity check on all wires in the Video Cable.
(An economical, yet decent enough multimeter for this test, can be purchased for around $5 to $12. A multitude of store carry them. An auto parts store is but one example)

Video cable checks out?
The next suspect is the LCD screen.
However, read on.

Primer:
An LCD screen does not produce enough light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

An Inverter (Screen Inverter) is used to convert the power (Electricity) from the laptop, for the LCD screen, and Inverter.

90 PERCENT OF THE TIME the fault is the Inverter.

Example of a screen inverter for a Dell Inspiron 1100 Notebook PC,

http://www.nylaptopparts.com/index.php?main_page=product_info&cPath=91_95_125&products_id=547

An expensive (Read - Sensitive) multimeter can be used to check a screen inverter. Not something everyone has laying around, or access to. In this case I would suggest replacing the Inverter.

(The screen Inverter is also easily accessed, AND much cheaper in comparison, than the LCD screen. Again, 90 percent of the time the fault is the Inverter )

IF, the Inverter does not cure the problem, then the problem is the LCD screen.

Review;
Check the display with an external monitor. Display checks good, run a continuity check on the Video Cable.
Video Cable checks out OK, go to the Inverter.
Inverter does not cure the problem, the problem is the LCD screen.

BEFORE beginning to disassemble;
Remove ALL power to the laptop. Remove the AC adapter (Charger), and Battery.

Observe Anti-Static Precautions.
(I would also advise using an ESD wrist strap, and connect it's alligator clip to a good ground source.

Average cost of a decent ESD wrist strap, is around $3 to $6.
I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
{Electro Static Discharge)

Use a multi-compartment container for the various screws you will remove.
label each compartment for the area the screw/s come out of.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder.

SOME screws look VERY similar to other screws.
Do Not mix them up.

For additional questions, or to have me explain anything I have stated here, post in a Comment.

It displays colorful lines on the monitor...cant see nothing


Test your laptop with an external monitor and find out if the external video goes bad too. If both, internal and external images go bad, you have a problem with the video card.
If external works fine and only internal goes bad, most likely it’s either bad video cable or LCD screen failure.

Nvidia F5200


You could try right-clicking your desktop and going to settings. There you need to select the other (grey or a 2 in it) monitor and select "extended desktop". If that doesn't help, check the monitor cable. (maybe try another one, you never know...)
If it's still not detected, you could look around the NVidia control panel (I myself have always had ATi graphics cards) for a "detect monitor" option.

I have a laptop HP pavillion dv6000 with Nvidia 8600 M GS videocard. When I tried to connect it to TV with Svideo cable it is not Identifying the TV as second monitor.


Greetings,

You need to configure the nvidia software for dual monitor mode. And refer the manual of the laptop to find the hotkey to enable external display device. If you provide the exact model number of the laptop I will be able to provide much information to you.

Revert back for clarifications.

Hey,

in windows, right click on your desktop, select properties, then settings and then click on the 2nd monitor, make sure the 2nd monitor is attached to the dvi, when the computer was turned on. so the 2nd monitor will appear in the settings.

this will give image from the dvi output. to get objects to the 2nd monitor drag them out of a corner of the first screen. debending on what side the monitor is at.
Let me know if you need anything elsed.


Thanks,

Secondary monitor from a Laptop


If your laptop doesn't automatically detect the external monitor, there will be a function key you need to press to activate the external monitor connector. It's often on the top row of keys, but different manufacturers put their function keys wherever they like. The key will normally have a marking that looks like a little monitor screen. Connect your external monitor, hold down the F or Fn key and press the monitor key when you find it. Usually the first press will turn on the external monitor and turn off the laptop screen, then the second press turns the laptop screen back on. Some brands or models may not turn off the laptop display, though.

I just got a computer and it worked when we were packing it up. Before we put the computer up my friend wanted to see if he could put a newer video card into it. Well it didn't fit so he put the old one...


he didnt push the card all the way down simple open it back up pull card out and "you" push the card back into slot
the bar on should be flush with case

i hope your friend didnt put it on something that had electrical charge that staticed the card to death
but more than likely he didnt push the card down all the way make sure monitor cable is tight and flush with card in back of comp
if you still dont get picture try another monitor you could have damaged something in monitor in your move
