Toshiba Satellite P105-S9722 white screen on stat up

Don't assume. Diagnose.

Problem could be graphics chipset, Video Cable, screen Inverter, or LCD screen.

Graphics chipset:

1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.
(Back of laptop - Blue)

Example of a VGA Cable, and a VGA connector, (Port on laptop),

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

If you have a CRT type of monitor (Looks like a small TV), you can use it, or a flat LCD screen monitor with a VGA cable.

The Toshiba Satellite P105-S9722 Notebook PC, also has a DVI connector on the back of the laptop. (Next to the blue VGA port)
You can connect a flat LCD screen monitor with a DVI cable.

Example of a DVI Cable, and DVI connector,

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

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default the display should be on the external monitor.

If not;
Press, and hold down on the Fn key, (Bottom left), and tap once on the F5 key.
The F5 key is the Display Toggle-Over key.

You will see a list. It 'hot cycles' through the list, until you come to the external monitor device you are using.

External monitor display shows no white screen?
Your graphics chipset is good.
Go on with the diagnoses.

Problem is with the Video Cable, or in the Display Assembly.
(Screen Inverter or LCD screen)

Video Cable:
The Video Cable attaches to the motherboard under the Switch Cover, and about at the F2 and F3 keys.
It then routes under the left Hinge, and up into the Display Assembly.

From there it connects to the screen Inverter, and back of LCD screen,

http://www.irisvista.com/tech/laptops/toshiba-satellite-p105/big/toshiba-satellite-p105-11.jpg


From;

http://www.irisvista.com/tech/laptops/toshiba-satellite-p105/take-apart-1.htm

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-P105-P100/remove-lcd-screen-inverter-1.htm

Due to normal opening, and closing of the laptop, the Video Cable may become pinched, and pulled on.
This can lead to a simple loose connection of the Video Cable TO the motherboard, or TO the back of the LCD screen.

(The screen Inverter connection should also be checked)

Visual inspection will NOT do. You need to physically see if you can plug the motherboard connection, and LCD screen connection in.
It could be just loose enough you won't be able to see it, but will affect the display.

Sheath of Video Cable needs to be visually inspected for signs of damage. Signs of damage to the sheath, may also mean damage to the tiny wires inside the sheath of the Video Cable.
(Stretched/Broken)

Assurance that the Video Cable is not the problem, means checking out, or have checked out, with a multimeter set to OHM's, to run a continuity check of all the wires.
('Mom and Pop' computer store. See if they will check it)

Or simply replace the Video Cable. (After you fire up the laptop, and see if loose connections was, or was not the problem)

http://www.batterysupport.com/toshiba-satellite-p105-s9722-cable-p-377633.html


(Left side connects to LCD screen. Right/Top connector goes to motherboard. Right/Bottom connector goes to screen Inverter)

Video Cable checks out OK?
Go on to screen Inverter.

http://www.ebay.com/itm/TOSHIBA-Satellite-P105-S9722-laptop-lcd-Screen-Inverter-/250759700669


The plastic thin frame in front of the LCD screen, is the Display Bezel.
The screen Inverter is behind the Display Bezel, and mounted at a location towards the bottom of the LCD screen frame.

A screen Inverter is tested with a sensitive multimeter. Read fairly expensive,

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

It is for this reason that those who do not have access to a sensitive multimeter, usually just replace the screen Inverter.
(Also low cost, and ease of access to replace)

Screen Inverter checks out OK?
Problem is the LCD screen,

[ Bet it's the video cable, or screen Inverter, that is the problem ]

[ Primer:
An LCD screen cannot produce light by itself. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL, (Or two of them), or a series of LED's.
(Light Emitting Diode)

The Toshiba Satellite P105-S9722 Notebook PC, uses One CCFL for a Backlight.

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

Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height,

General example,

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/

A CCFL contains -> Mercury, just like Fluorescent lighting used in homes, and businesses.

A screen Inverter is used to convert the power from the laptop, for the Backlight, and LCD screen.
90 Percent of the Time the fault is a bad screen Inverter.

Primer over.

I've installed Windows 7 on my Toshiba Satellite P105-S9722 Laptop - and I keep getting white screen. I updated the BIOS to 4.8 and installed 4 gb of memory. I've tried different video drivers but keep...

This laptop came with either XP or Vista on it and if you wish to use Win7 32 or 64bit you must install all of the drivers and preferably make a fresh install. There is only one video driver that will work!
To gain access to the correct drivers, go to Toshiba.com and log your laptop in. The web site will advise you on which drivers you require.
I feel sure that that is the only problem you have that is giving you this headache.
Don't forget unless you load 64bit Win7 you may not be able to utilize more that 2048 Mb of memory.

Toshiba Satellite P105-S9722. monitor will not

Hi,
The problem is the inverter cable or the inverter itself.

If you have any warranty left on the laptop then i recommend you take advantage of that and send it in for repair, or you can deal with this 2 ways.
Fix the problem yourself.
Remove the screen bezel (plastic screen surround), this will reveal the whole screen. At the bottom of the screen you will see an elongated piece of circuit board with wires coming from either end covered by frosted plastic.
That is the inverter, check the connections on the inverter and power the laptop up to check the display, to remove it gently pull the plugs from each end and remove the screw from the middle and pull the board away.
Look at the inverter for a copper coil, if you re-solder the solder points around the coil you may find it works again as components that suffer from extreme heat the solder joints dry causing bad connections, re-floating the solder solves the problem in 90% of cases.

Take the laptop for repair.
In this case all you have to do is source a reputable PC repair store and take it in for them to fix. (it should be fairly inexpensive).



Good luck.

My lcd screen does not come on when I start my laptop.

What I am hearing is that your computer turnjs on but the lcd screen is black? Can you make sure all the status lights are on? (battery, adapter, and on your laptop system.) If all the lights are on, check your lcd screen's resolution setting...Press the buttons that brightens the screen. One, two or three times should get it going. If the contrast buttons do not turn your lcd on, it could be the monitor itself. (One other thing...check for any Visible damages on the screen, ie. cracks or missing pixels (if you can see)...
