Usually located around the hinges.Be careful... Try removing the hinge clips there is a ribbon cable ...these can break easily.but check that the connection into the main board has not dislodged before inspecting the screen area.the screen housing clips together at the bevel edges.be aware that faults can just be failed backlight,,,,inventor,,,,loose connections ,,,,broken ribbon,,,,dead or cracked lcd.

Testimonial: "there is a white wire off in the screen.the wires under keypad is connected.."

Screen not working

I really have no idea what you are saying. You cannot commit a mistake with the wires because they are specifically shaped and designed to omit that error. Everybody including you knows that. Black and white wire coming from the screen? Did you mean you actually opened your computer started tinkering with it? If that's the case well if it still has warranty you voided it. Either way you will need to have a technician to actually take a look at it.

Why is my toshiba satellite c655d-s5200 screen is black and i can faintly see

Okay. Got a bright flashlight, and some tape?

OH I'M JUST KIDDING!

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 a series of LED's.
Light Emitting Diode.

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,

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

View the last 11 photos ]

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

The Toshiba Satellite C655d-s5200 uses LED's for the Backlight, and No screen Inverter,

http://www.laptopscreen.com/English/model/Toshiba/SATELLITE~C655D-S5200/

Which narrows your problem down to two possibilities;
A) Problem with the video cable
B) Problem with the LCD screen.

I state LCD screen, because you won't be replacing the LED backlighting. You have to buy the entire LCD screen assembly, as shown in one example above.

(Example is shown for reference, not advertising. You may find a better deal from a reputable dealer, also)

Video Cable:
The Video Cable is attached to the motherboard, under right about at the number 6 key, on the Keyboard.

It then goes across to the Left Hinge, and up into the Display Assembly.
From there it goes to the back of the LCD screen.


From everyday normal opening, and closing of the laptop over time, the video cable may become pinched, and pulled on.
This can create a loose connection at the motherboard side, and/or LCD screen side.

It can also cause damage to the video cable. If the sheath of the video cable shows visual apparent signs of damage, the wires inside may be damaged also. (Stretched/Broken)

Laptop off, ALL power removed, (AC adapter {Charger}, and Battery), I suggest checking the motherboard side connection first.

A visual inspection will Not do. You need to physically see, if you can plug the motherboard side plug of the video cable, into the connector on the motherboard.

A loose connection that is not apparent to the ***** eye, is all it takes to have a problem.

You can click on any photo to enlarge,

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-C650-C655/disassemble-toshiba-laptop-3.htm

Stop on Step 22. Access to the motherboard side of the video cable.

A word on the Keyboard Cable, and it's connector on the motherboard; (Steps 9, 10, and 11),

The Keyboard Cable stays with the Keyboard. It removes from the motherboard connector. The Keyboard Cable has NO plug, or connector on the motherboard end.

The Keyboard Cable is a FFC. Flat Flex Cable.
It has flat gold plated contact strips on the motherboard end.

The motherboard connector is a ZIF connector. Zero Insertion Force.
In Step 11 you can plainly see this connector.
Has a large white rectangular BODY on bottom.
The smaller rectangular shaped piece on top is the Locking Bar.

The Locking Bar does NOT completely remove from the Body.
If it does it is broken, and means motherboard replacement.
Hence why I am being so detailed.

I am sure you use great finesse, but wanted to advise you in advance of the 'danger'.

The Locking Bar is moved towards the LCD screen, and as advised about 1 millimeter. ( -> O <-)
There are Tabs on the Locking Bar. One on each side. Usual procedure is to use your thumbnails on these Tabs, and ease the Locking Bar forward.

Now gently tug on the Keyboard Cable. You may have to gently move it side, to side, to break the Keyboard Cable loose. They sometimes get stuck over time.

Pretty stiff? Better check to see if you have the Locking Bar fully unlocked.
The Keyboard Cable MUST go back in the same position, and through the same plastic Latches and Channels.

(As do all the cables, or you may pinch them, and also will not be able to get the laptop back together correctly again)

Make a mark on one side of the cable, (Away from the gold plated flat contact strips), and a matching mark on the ZIF connector of the motherboard, if you need to.

You can slip the Keyboard Cable back in, Ram Memory, DVD drive, and Battery, and reconnect the AC adapter, to see if this was the problem.

Still no?
Check the LCD screen side connector of the video cable. Is it tight?

http://www.irisvista.com/tech/laptops/Toshiba-Satellite-A665-A665D-A660-A660D/remove-replace-lcd-screen.htm

LCD screen connected, turn the laptop on.
Was this the problem?
No?

Even if there are no apparent signs of damage, you may wish to take the video cable down to the nearest 'Mom and pop' computer store, and ask them to check it for continuity. This way you can see if any wires are broken inside. (Labor charge may be free to $5)

(My thinking is if you go to a large computer repair shop, they are going to want to repair the laptop, or sell you an LCD screen, or a new laptop. "Oh that old thing? For 2995 I can put you in the seat of this baby!" )

Or since the video cable is very economical, you may wish to just replace it.
Just one example from a quick search,

http://www.ebay.com/itm/Toshiba-Satellite-C655D-6017B0265601-LCD-Video-Cable-Genuine-OEM-Laptop-Tested-/290753862740?pt=US_Video_Cables_Adapters&hash=item43b247dc54

[Black end on right is motherboard side, gold colored end on left is LCD screen side ]

Video Cable ruled out your problem is the LCD screen, or to be more specific, the LED backlighting.
Replace the LCD screen.

I have a toshiba c655d but I the screen is too dark, when I connect an external monitor it works just fine. Any ideas?

Hi boris jurado...

Sounds like your LCD is faulty, if it works with another external monitor, then that is normally the problem.
You will need to change your LCD to correct this problem.

Toshiba TE2100, Sreen flashes rapidly on and off, If I tap it on the side, it stops flashing, bu intermitently starts again. Seems lide aloose connection in the wiring to screen, as computer will still...

Sounds like you are correct about the loose connection. There is a thin ribbon cable that powers the monitor.

You will have to download instructions for taking your laptop apart, but once you do, simply reseat the ribbon cable. That should fix it! Good Luck.
