Question about Toshiba VGA Board Graphic Card

1 Answer

External monitor connection problem

I've got a Toshiba laptop; Satelite A105 that is 2 yrs old to be
exact. The connection to the external monitor is experiencing
intermittent connection problems. When I jiggle the VGA cable where
it plugs into the laptop I can get it to connect and stay on but if I
move anything it drops signal again. Same problem persists after I
put in a new VGA cable.
What is the fasest, cheapest way to determine where the problem and
fix it?

The problem is with the laptop. The femal VGA port is slodered to the motherboard. Once the laptop's MB has been removed you'll most likely find the solder holding the VGA in place is most likely cracked/loose. The fix would be to remove the old solider & apply new.
I can't guide you through disemble, its complex. I can include a site to help you with this.

If you find this all a little too involved it might be worth taking it to a pro.
At this link you can order A105 parts if needed.

1) Laptop OFF, monitor OFF.

2) Connect the VGA cable of the VGA monitor, to the VGA port on the Left side/Rear of the laptop.

You can use a CRT monitor (Looks like a small TV), or a flat LCD screen monitor with a VGA cable. (Or DVI to VGA adapter on the cable)

3) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By default the display should show up on the external VGA monitor.
If not,

Press the Fn key down, and hold it down. At the same time tap once on the F5 key.

No display? Hold the Fn key down again, and tap once more on the F5 key.
There are at least 3 options available;

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

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.

Ok here is my problem. I have an Acer Aspire 5536 and the graphics card is out. I need to know how I fix this problem(as in if I can get a new card or a new motherboard.) I love my laptop and my whole life...


Sorry to hear your having problems with your Laptop.

First thing we can try is to see if you can use an external monitor.

Use the (Blue) VGA connector on the side of your laptop and a VGA cable to connect it to the monitor. See Below.


greed03_13.png

greed03_3.jpg
Once you have your laptop connected to the external monitor, turn it on and see if it comes up on the external monitor.

If it doesn't, you might have to hold down the Function Key and press F8.
This will cycle between the laptop monitor and the external monitor.

greed03_14.png
If that works, it might be the laptop screen has probably gone bad.

If nothing still comes up on either screen, it's probably time to get a new Video Card or Motherboard.

If you still have questions, please send me a message and I'll see what i can do to help you further.

Hope this helps!

Use your restore disk, or if you have a Windows OS disk, bootup with that.
When you see the screen that gives you an option to "Repair Windows" hit the "R" key. You will be taken to a DOS prompt. Choose the Volume you want to repair (Usually number 1) then it will prompt you for an Administrator password. If you have never put one on the system, simply hit Enter. The it will take you to "C:\Windows" Type in the following...
"CHKDSK /R" (without the quote marks and hit Enter. Let chkdsk utility see if it can repair the volume. It will prompt you when it is finished.

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.

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.

External monitor connection problem


If you are comfortable with opening your case up you need to follow wiring from plug to system board checking proper connection to the board. If not comfortable or connections are ok then a local computer shop is your best bet.
