Re: graphic card on sony pcg-gr15

There is no replacement for this as the graphics controller is onboard, as in built into the motherboard and not a seperate dedicated graphics card. You can try updating the driver but i would firstly go to my computer>right click>properties>hardware tab>device manager>click '+' sign on display adapters, select the adapter and right click and select uninstall. Restart pc and the graphics driver will be reinstalled. If no change, then it could be that the lcd or the back lighting is faulty and requires a qualified repairer.

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),

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,

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.

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.

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,

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.

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.

I have a sony vaio laptop and the screen has all lines on it,what could it be?

It is most likely the LCD assembly, but to eliminate other possibilities, connect up a desk top monitor to your laptop, and toggle to the external display and check the picture on it. If it is good, then your LCD is bad, if the picture is still bad, you have on board video problems, and not easily fixed. To toggle to the external display mode, you usually have to hold down the function key and hit the function key with a picture of a TV screen on it.

Turned my gateway mx3414 laptop off, when I turned it back on the screen was black, turned off and restarted several times always just a black screen.

You may have a faulty inverter or defective CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Dell Inspiron 8200 ATI Mobility Radeon 9000 Green Screen Problem

Try connecting an external monitor to the laptop. After your computer is attached to an external monitor, press the <Fn> key and the <F8> (CRT, LCD) key to switch the video image to the display. If the external monitor works, the computer display or video controller may be defective.

SONY PCG-GR315 graphic card

If it appears fine on an external monitor, it seems to me that the problem is most likely in the laptop's LCD panel rather than the video card. I did a google search and turned up exactly zero results regarding the SONY PCG-GR315 Are you sure you got that model number right? In any case, chances are your laptop's video device is not upgradeable. My advice is to go to a repair center or what-have-you and find out if it's the card or the panel; panels can be replaced more often than other integrated hardware.
