How to check out or look for problems with the lcd monitor on toshiba satellite p100

When the lcd moitor is disconected and a external monitor connected the computer works fine. When lcd is reconnected it tripps the overload portector. I don't know if there is a problem is with the lcd monitor or weather the power supply can't handle it.Also to mention that when the problem first started it would run for along period of time then the protection switch would go on.Then the period of running would get shorter and shorter. Now it will not run with it's own lcd monitor.The fan was cleaned,new thermal grease put on .this didn t make any difference.Would appreciate any advice related to this problem. THANKS

Possible that PC is hanging up as there is fault on the OS ( operating system) . So open the internet options in the browser and clean all the cookies, temporary internet files, defragment the drives and RESTORE the PC to an earlier set date.

You can use a registry cleaner like Advanced system care. Download from the site and check you system for corrupt files. Also use a good antivirus software which is active to keep your system performing without an attack on the OS. Remove all unnecessary programs installed which you do not use all the time and clean up the drives. This will free up the space and make your system faster.
If there is no response but the PC tends to work slower and occasionally hanging when a program is being executed then you might have to install the OS once again. Install the OS and then an antivirus before the drivers of the PC is installed.

Also a fault on the memory can be another issue but an hardware problem that needs a probe.

Toshiba satellite pro p100 screen problem


The LCD can be replaced. The part is around $50-$75 I believe. It can be tricky to replace, but if you take your time, you can save money by doing it yourself. The screen sounds cracked or broken, and black & white will not work either.

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.

http://shop.mcccomputers.com/network-modem-cards/6037-toshiba-satellite-p100-p105-p105-s6104-p105-s9722-video-board-256mb-ts15082.html

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.

Average size is approximately 2mm Thick, and the length is close to the height of the LCD screen. 2mm is a little larger than 1/16th of an inch.

This means the CCFL can be broken quite easily, as it is fragile. (You also DO NOT want to be cut by a Fluorescent lamp )

A screen Inverter converts the power from the laptop, for the Backlight, and LCD screen.

Toshiba satellite monitor is scrambled, how to fix?


Check to see if the problem is the screen Inverter, or the graphics chipset, or the LCD screen.
Use an external monitor as a test.

If the screen of the external monitor shows a scrambled display you have a problem with the graphics chipset.

If the screen of the external monitor does Not show a scrambled display, you have a problem with the screen Inverter, or the LCD screen.

90 PERCENT of the time the fault is the screen Inverter.


External Monitor;
1) You can use a CRT monitor, (Looks like a small TV), as a VGA monitor,
Or
2) You can use a flat LCD screen monitor that has a VGA cable.

A) Laptop OFF, and monitor OFF, attach the VGA cable from the External monitor, to the VGA port on the Toshiba Satellite A205 series Notebook PC.

This is an example of a VGA cable, and it's connector, and a VGA connector on the laptop,

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

B) Turn the monitor on. If it is a CRT style let it 'warm up'.
Turn the laptop on.

C) The display is supposed to automatically show up on the external monitor.
If it does not, press, and hold down on the Fn key, and also press the F5 key.

Still no?
Holding the Fn key down, tap the F5 key again.

Display good on external monitor? Problem lies with the screen Inverter, or the LCD screen.
Either OR.

Primer:
An LCD screen does not produce light. 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 electricity provided by the laptop, for the LCD screen, and Backlight.

As previously stated, 90 PERCENT of the time the fault is the Inverter.

Laptop open looking at the display assembly, the plastic thin frame in front of the LCD screen, and surrounds the LCD screen, is the Display Bezel. (Resembles a picture frame)

The Display Bezel is removed to access the screen Inverter.
The Inverter is right behind the Display Bezel, and located at the bottom area of the LCD screen.

The Display Assembly has to be removed from the laptop, to remove the Display Bezel.
Toshiba's term for the Display Bezel is Display Mask.

The Toshiba Satellite A205-S5804 Notebook PC is one of the Satellite A205 series of Notebook PC's.
This is a link to a free Service Manual for a the Satellite A205 series of Notebook PC's,

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-toshiba

Scroll down to the second Satellite heading. The one that begins with Satellite A10.
Scroll across, and click on A200.

After you click on A200 it may take as long as 30 seconds before the first page comes up.
It may also take additional time for the file to fully download.

At the top of the PDF file is the page number box. It is to the right of the Down Arrow.
Go to Page 146.
4.10 Display Assembly

Page 151 shows how to remove the Display Mask.
4.11 Display Mask

Page 153 deals with the screen Inverter.
4.12 FL Inverter Board

Takes a really sensitive (Read fairly expensive) multimeter to test an Inverter.
Due to the low price, and ease of replacing, the screen Inverter is replaced to test whether the old one is bad.

Example of a screen Inverter (FL Inverter Board) for a Satellite A205-S5804 Notebook PC,

http://www.batterysupport.com/toshiba-satellite-a205-s5804-inverter-p-216526.html

Compare to the price of a replacement LCD screen,

http://www.laptopscreen.com/English/model/Toshiba/SATELLITE~A205-S5804/

To summarize so far;
1) Display shows good on external monitor. Replace screen Inverter. Still the same problem? Replace the LCD screen.

2) Display on external monitor is scrambled also?
Fault lies with the graphics chipset.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

The graphics chipset is a GPU.
Graphics Processing Unit,

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

The GPU for a Toshiba Satellite A205-S5804 Notebook PC (Part Number PSAF3U-0NR00V), is an Intel (Mobile) GL960 Express,

http://en.wikipedia.org/wiki/List_of_Intel_chipsets#Core_2_mobile_chipsets

It is soldered directly to the motherboard, therefore it is Integrated Graphics.

{Integrated Graphics is also known as OnBoard graphics.
ON the motherBOARD.
The GPU is soldered to the motherboard.

In comparison if the GPU were soldered to a removable adapter card, it would be a graphics card, and Not integrated graphics }

This means if the graphics chipset is found to be bad, motherboard replacement is the solution.

Hi I have a toshiba satellite laptop with a 17"


Hi,

Have you tried to connect an external monitor to see if the thin line is still visible? If not, you can try it but if you do not have an external monitor, you can just access the BIOS (Basic Input Output System) by pressing F10 or Del (whatever key is designed on your laptop to access it) and check if still visible. If it is visible in the BIOS, you may need to replace the LCD inverter or the LCD of your laptop. However, if it doesn't appear in the BIOS, you can try to update your video card driver.

Hope this helps.

MY SATELLITE A505 HAS A DISPLAY PROBLEM


Does the Toshiba appear to bootup and the hard disk LED is flashing?
Can you see a dim image when you view the LCD screen at a sharp angle?
Connect an external monitor to the external video port and power up the external monitor first and then the Toshiba, if you get a nornal image on the external monitor the the video card is OK and the fault is the LCD screen. The problem could be the CCFL lamp or the inverter.
Get back to me with the result of these test and I can advise what to do next..

Good morning, Kevin!
Sounds like an LCD problem. You can verify this by hooking up an external monitor. The external monitor will probably show a good display.
After verification of the problem,you may want to try to replug the LCD cable at both ends, just to see if that corrects the situation.
If that resolves things, all is well and good. If not, you may need a replacement LCD.
If the external monitor shows the same display, you may have a motherboard problem.
Hope this information is of some help.
