Flickering Screen on Model P105 Toshiba Satellite

I have the same problem with the flickering screen of the Toshiba Satellite Model P105 lately. It happens mostly at start-up, sometime goes away after a bit. I've tried opening and closing the top and sometimes that works. It is getting worse though and today I can hardly read the material on the screen for all the flickering on the screen. (like bad reception on a tv set)

On the back of the LCD is a cable that goes from there to the Motherboard. Try reseating that cable on both ends. If that doesn't fix it then it has to be a problem with either the screen or the cable behind the screen.

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.

Just a quick note, before you go replace the entire screen, make sure it's not just a wiring problem. If so, it doesn't cost as much to replace the wires connecting the screen to the laptop. LCD's are much more expensive!
As for replacing the display, this website has information on the display, along with the ability to purchase it from their site. http://www.pelltechnology.com/Toshiba/Laptop/Toshiba-Portables-Satellite-P105-Series-S6024/Toshiba-Satellite-P105-S6024-LCD-Screen-Replacement-P350475.asp
Hope this works!

Toshiba Satellite P105-S6024 screen problem


If this is happening once the PC has fully loaded the OS. You then possibly have a bad inverter or bad LCD screen. Try reloading the video driver and see if this helps. If it doesnt then you will have to replace the inverter or LCD screen. A local repair shop should be able to replace these. And I would have them try to replace the inverter first as it is usually cheaper then the screen.

Best of luck and have a Happy and safe 4th of July weekend!

When you get vertical lines from the top of the screen to the bottom of the screen, it means you have bad LCD panel, you need the new one. It will get worst with more lines as time goes by.

Toshiba laptop screen goes white while in use


The problem actually will happen to all notebooks. Some problems happen on certain models more often. Also, it depends on how often the user closes and opens the notebook.

The data cable is usually the problem and it happens where the most pressure on the cable lies. The data cable will most likely need to get replaced. It is recommended that you take it to a service center. The cost should not exceed $145.00

thanks adi

I have vertical lines (15 of them now) on my Toshiba laptop.


I'm afraid when you see vertical line on an lcd panel, it most likely is screen failure. Ebay has plenty of screen from good companies in Texas. I get most of my screens from Ebay store LCDTECH99. They have the best prices, most screens are under 100 bucks and they ship right away. The Toshiba screen is an easy repair, Only the bezel needs to be removed in most cases. Below is a guide to show the process.

I have a line going down the middle of my toshiba laptop, any suggestions??


Usually indicates first signs of LCD going out. Must replace monitor or replace parts inside the lcd screen.. Both are costly and the best way is to replace the screen but depending on the age of the laptop you are better off investing in new low end model. Most laptop screens go from 150-250 and newer lower end laptop goes for 400 so tough call.
