Question about Toshiba Satellite A105 Notebook

1 Answer

Want to display movies via my Toshiba satellite A105 on HDTV

How do you set up the secondary display, which is connected to the LCD HDTV via 15-pin VGA cable, to have 1280x768 resolution? I tried doing it from the Control Panel->Display->SEttings, but it seems to revert to 800x600 on the TV monitor. The computer product id is A105-S4284

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 shattered want to connect to HDMI for HDTV. Boots up on TV then says no signal what should I do?


Press the FN+F5 key, this is the hotkey combination that switches your display from the LCD to the external output. If this does not work, make sure you are using the S-Video output on your laptop to connect to the TV, since your Toshiba model does not have an HDMI compatible output.

If you've replaced the LCD Panel already, then chances are good, the failing part may be the FLR inverter. It's a thin little chip about 3 or 4 inches in length that bridges the connection between the LCD and the motherboard. It's location varies from computer to computer though, so you may have to check with manufacturer documentation. They're not too terribly expensive to replace though, much cheaper than the LCD panel, anyways.

Connecting notebook to tv with s-video


secondary display is like a blank desktop to show open windows or programs you have to drag them off your desktop to the left or right, whichever you set the TV to. to fix this look for a button that has two monitors on it on the F-row. F1,F2,etc. Hold down the Fn key and push the display function key at the same time. You might have to push the display button a couple times.

If I open my Satellite A105 display too far, it goes black.


Hi, This is definitely a loose connection problem.
Does the screen go completely black or just a part ?
If its just a part, LCD is defective. You may have to change the whole LCD screen. You can get one for ~180$ from ebay
If the whole is turning off, I guess the power cable might be little loose.
You can open the LCD panel and check if you know what you are doing.
Else take it to a normal technician and ask him to open the LCD panel and see it.

LCD display problem


My Toshiba Satellite does a similar thing, It goes gray while I am working on it. The only way to continue to work on it is to complete shut it down manually and reboot. I took it to Toshiba they said nothing was wrong.
