Display divided into 3 parts


LCD screen cracked, and Three even strips going across? Doubtful. Haven't seen it but I always have my mind open.

Three strips that are irregularly shaped? Look like glass that has cracked?
'Jagged edges'?

LCD screen is broken.

Three even strips indicates to me, that there may be a problem with the Video Cable. Then the screen Inverter is next in the diagnoses.
My money is on the Video Cable.

ALL power removed, Anti-Static Precautions FOLLOWED, I would check out the graphics chipset first.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port on the laptop.
Left rear side. This is an example of a VGA Cable, and VGA connector. (VGA port on a laptop ),

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

(Color of connector does Not matter. It is generally Blue, though)

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

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

There are at least 3 display options available;
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 F5 key. (The F5 key is the Display Toggle-Over key)

No display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F5 key.

Is the display on the external VGA monitor, the same as the internal monitor of the laptop?

Problem is the graphics chipset.

Display is fine on the external VGA monitor?
Problem is the Video Cable, screen Inverter, or LCD screen.

Video Cable:

A) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A105/big/Toshiba-Satellite-A105-14.jpg

Switch Cover removed, Keyboard removed. Shows you where the Video Cable plugs into the motherboard.

B) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A105/big/Toshiba-Satellite-A105-21.jpg

Palm Rest Cover you can see the white rectangular connector, for the motherboard side of the Video Cable, at the top left.
It's above the black cable, and near the screw hole.

The Video Cable leads from the motherboard, up through the left Hinge, and into the Display Assembly.
From there it connects to the screen Inverter, and back of the LCD screen.

http://www.ebay.com/itm/Toshiba-Satellite-A105-6017B0050801-LCD-Video-Cable-Genuine-OEM-Laptop-TESTED-/290754851160?forcev4exp=true&forceRpt=true

In the photo, (You can hover your mouse cursor on it to enlarge), the right side connector plugs into the back of the LCD screen.

The black connector to the far left connects to the motherboard.
The small white connector at the top with the Red, Green, Black, etc wires, connects to the screen Inverter.

(The small Black cable, that comes out from the black motherboard connector, is a Ground wire )

Due to the close proximity of the Video Cable to the left Hinge, it can be pulled on from just normal opening, and closing of the laptop over time.

This means the Video Cable connection on the motherboard side could be loose, or the LCD screen side, or both.

The diagnoses is to PHYSICALLY check BOTH connections. A loose connection at the motherboard, or at the back of the LCD screen could be so small in distance, that you will not see it with the human eye.

Could also result in damage to the Video Cable.
View the Video Cable with the Switch Cover removed, and see if there are any obvious signs of damage to the sheath of the cable.

If there is there could be damage to the tiny wires inside the Video Cable. (Stretched/Broken)

Use a multimeter set to OHMs, to check all wires inside the Video Cable for continuity, or have a 'Mom and Pop' computer store check it for a few bucks, or replace the Video Cable.

Video cable connections are tight? Video cable continuity check checks out OK?
Screen Inverter.

The test for a screen Inverter is to use a sensitive multimeter.
Read fairly expensive.

http://www.fonerbooks.com/test.htm

Not having access to a sensitive multimeter that you can use, means just replacing the screen Inverter. Seems like 'part changing', and it is, but you have to work with what you've got.

http://www.sparepartswarehouse.com/Toshiba,Satellite,A105,Laptop,Inverters.aspx

Find THE model number for your laptop, and the correct screen Inverter. A screen Inverter, and an LCD screen are a MATCHED unit.

Screen Inverter is checked out to be OK, or replaced, and symptoms are still the same, the problem is the LCD screen.

Remember, the first part of the diagnoses was to see if the divided parts were EVEN going across, or jagged and irregularly shaped.

Jagged in shape, and not even strips going across, means cracks in the LCD screen.
Replace.

Screen is white with black vertical lines upon booting up. I can't get beyond this screen.


The video card (built-in on the motherboard) maybe faulty or the LCD screen is faulty.
Connect an external monitor to the video port of your laptop, power up the monitor first then boot up your laptop. If the video card id OK then the laptop will automatically divert the video to the external monitor. Then the problem is a faulty LCD screen.
If the external monitor also displays black vertical lines then you have a faulty video card and since it is part of the motherboard it is impossible to fix.

When i tilt the screen a certain on my acer aspire one d150 netbook all the white turns blue and black turns red, what can this be?


This indicates that the wire bundle running through the hinge has been compromised. Some wire has frayed apart and is making intermittent contact with itself or the lid movement is causing the wire bundle to pull on one of the video connectors.

In order to fix this problem, you will need to remove the netbook's front hinge cover & check the bundle of wires connecting the motherboard to the LCD screen. If this bundle of wires is damaged, then you will have to get it replaced.

I recieved a ds lite with water damage and the four odd wires on my ds lite motherboard all come off does any one have a diagram of where the wires might go thanks please help


from the tom screen there should only be 2 wires 1 black and 1 white. The white wire is the mic that plugs straight onto the board, and the black wire which plugs onto the wirless insert which attaches onto the board. the other 2 wires could be loose speaker wires if there is another black and a red wire, other than that could you explain a bit further what the wires actually look like.

Most Mobo's have printing next to the places that are jumpered or pluged into. The ones you need sould be close to the edge of the mobo, that is close to the front {power button} side.
