Question about Toshiba 14" LCD Monitor

Open Question

Toshiba Satellite Laptop monitor has discoloration and static

The white areas are pinksih and the black areas bright neon green. The problem has gone away on its own but comes back if the laptop monitor screen is moved, as if the problem is a cable of some sort in the hinge. I've plugged the computer into other monitors and know it's working fine. Is it worth fixing the monitor on the laptop by paying someone? Can I do it on my own?

Sounds like you need a new Switch. Oxidation has probably built up in the switch. It can be fixed. Probably shop around for a certified tech who can replace it. The switch is cheap, Labor is starting around $65 - $90. You said you can faintly see the desktop. This is the invertor board inside the LCD assembly that causes this. Again if it needs to be replaced, the invertor is fairly inexpensive, labor isn't. The technician that ckecks out the laptop can determine what it needs. Yea, your right, it is a good laptop and it is worth fixing. Just a heads up, if the tech says you need a new motherboard, he's lying, find another tech.

SOURCE: Data Shows up only on External Monitor, not on Laptop Screen

If your system won't display anything w/o the external monitor. there's something wrong with the LCD's backlight. you may have to contact your laptop's manufacturer and check if this laptop is still under warranty. you may have to get the lcd replaced.

thanks.

SOURCE: Laptop monitor goes black

If you're working on the computer when that happens, it's not probably a power setting. Try to update your BIOS to the most current version at the toshiba support website (support.toshiba.com) & see what happens. Fixes the issue most of the time

I hope this helps.

Remove monitor on a toshiba satellite C875D-S7225


A) Remove ALL power. Remove the AC adapter (Charger), and Battery.

In the area you're going in, you do not need an Anti-Static wrist strap.
Do be mindful about Static electricity, though.

B)

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.

I have been using a Toshiba laptop model "Satellite A135-S2276", since January 2007 without any problem. Yesterday morning I was using the machine and took it to the university in my bag and in the...


Hello !

Since an external monitor works, it is the display's backlight or inverter board.

If you were experiencing discoloration in the screen (pinkish lower light hues) before it failed, that would indicate a CCFL backlight issue. If the screen suddenly went dim on you rather than a slow degradation the inverter would be indicated.

In either case, a technician in your area should be able to help. Evalaute to see if the repair is cost-effective.

Hope this helps.

How do I replace the keyboard?


next to the F1 key and the windows key (2nd upper key and second to last key) are two screws, usually under some covering. unscrew and lift top edge of the keyboard towards the trackpad to lay face down. Undo the wire ribbon by lifting the grey or brown tabs and remove ribbon and keyboard. Then install the new keyboard by inserting the ribbon on the place. Lock down with the tabs and put the plastic prongs (close to the space bar) into the laptop body first, and then close keyboard onto the final position. screw back in and thats all. nboulikas@gmail.com for any additional questions.

This sounds like something has messed up your crystals in your display, and while I do not know that much about laptop displays this sounds like it can only be fixed by a technician or by replacement.
