Sounds like you've shorted something against this led wire. Did you maybe forget to slip that thin piece of paper or plastic back in before installing the new palm rests?
Let me know if this helps

Pink screen


Problem can be;

1) Graphics chipset
2) Video Cable
3) screen Inverter (IF Used)
4) LCD screen

Diagnose to find out.
I need the laptop manufacturer name, and model number.
Model number can be found on the Bottom of the laptop.

Post back in a Comment.

A) Graphics chipset:

An external monitor is used to check, and see if the display is also pinkish on it; or it is OK. Info posted I need, I will detail this procedure out step by step.

Display good on external monitor means graphics chipset is OK.
(Mounting is usually the problem)
Means problem is screen Inverter (IF used), or Video Cable, or LCD screen.

B) Video Cable:

The Video Cable connects to the motherboard, in an area under the Keyboard, or under the Switch Cover.
(Depending on laptop design, Switch Cover may be an integral part of Palm Rest Cover)

From there it leads under, or close by the left Hinge; and then goes up into the Display Assembly.

IF, a screen Inverter is used, the Video Cable has a separate small cable that branches off; and connects to one side of the screen Inverter.
The main part of the Video Cable connects to the back of the LCD screen.

Just due to normal repeated opening, and closing of the laptop; the Video Cable may become pulled on, and/or pinched.
This can lead to a loose connection at the motherboard side, or LCD screen side. (and/or screen Inverter, IF screen Inverter is used)

Can also lead to a damaged Video Cable. (Stretched/Broken wires inside it)
This can cause a pinkish screen.

C) screen Inverter:

With Backlighting that uses CCFL/s for a Backlight, a screen Inverter is used.
(Cold Cathode Fluorescent Lamp)

For Backlighting that is LED, a screen Inverter MAY, or MAY NOT be used.
(First design LED backlighting seemed to. Later design LED backlighting, does not. Light Emitting Diode)

A screen Inverter is used to convert the power (Electricity), from the laptop; for the LCD screen and Backlight.
Screen Inverter going out, can cause a pinkish screen.

D) LCD screen:
Graphics chipset is good, Video Cable connections are good; no damaged Video Cable, screen Inverter is good (IF used); problem is LCD screen.

Awaiting manufacturer name, and model number.

Back light sometimes works


If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

I need a body case for my vaio vgn-nw120j/s


The panel you refer to is the Palm Rest Cover (Sony)

Covers the top of the body of the laptop, has the Touchpad in it, and the Keyboard is in the top/middle.

I would suggest going to Ebay, and looking at Laptops for Parts, or a laptop like yours that may have internal problems, or a bad LCD screen.

As for guidance in removal and replacement, I have no links to give you for this exact model.

I can however link you to guides that are similar, and should work;

1) http://www.insidemylaptop.com/disassemble-sony-vaio-vgn-fw170j-series-laptop/

The LED light/Power Button/Speaker Cover is different in shape.
(Strip of plastic below the LCD screen, and above the Keyboard.
There are different names for the various models)

2) http://www.insidemylaptop.com/replace-lcd-screen-sony-vaio-nw235f-laptop/

In case you wish to replace the LCD screen, lol!
Used to compare against the VGN-FW series, and to let you know, I know the VGN-FW series is a little different.

However after you have disassembled many laptops, you see that there is a simple specific pattern, for all laptops.

A) Don your ESD wrist strap, and connect it to a good ground source.
(Electro Static Discharge)
Average cost is around $3 to $6.

(I connect it's alligator clip to an unpainted surface, of the metal frame of an open, empty desktop computer case)

B) Lay a towel on a table. Make SURE it is static free. (Unless you have a workbench like I do, and static cover)

C) Laptop off, closed, and upside down on the towel, remove ALL power to the laptop.
Remove the AC adapter (Charger) and Battery.

D) Look on the bottom to see if there are arrows pointing to screw holes. Remove the ones indicated to remove the Keyboard, strip of plastic above the Keyboard, (If there are any), and Palm Rest Cover.

[ Use a multi-compartment container for the various screws you will remove.
If no multi-compartment container is available, substitute with a clean egg carton.
Label each egg holder for the area the screw/s come out of.

SOME screws look VERY similar to other screws.
DO NOT mix them up.

Make a record as you disassemble. Make notes, drawings, and use a digital camera, if available, or a video camera. (Use good lighting)
It's nice to have a record to refer back to, in case you are interrupted ]

E) Turn the laptop over to it's normal position, open the LCD screen all the way back.
Pop the strip of plastic above the Keyboard loose, then remove it.
Use CARE as there may be speaker wires, and LED light wires going to this strip. If you use a tool, (plastic Spud Tool?), do NOT damage the wires. These will have to be disconnected.

F) Remove the Keyboard. There should be 2 or 3 screws at the top of the Keyboard, holding it in place, OR there were screws you removed from underneath. (Bottom of laptop)

The Keyboard tilts up at a 45 degree angle, (Lift the back, or LCD screen side), then slides forward a little. (Towards LCD screen)
The Keyboard Cable is still attached, so do not try to remove it all the way yet.

The Keyboard is Not brought up to a 90 degree angle, when removing.
There are plastic tabs formed at the front of the Keyboard, which slide into the Palm Rest Cover. These can be broken off.

The Keyboard Cable does Not remove from the Keyboard. It removes from the motherboard.
The Keyboard Cable is a FFC. Flat Flex Cable.

It does not have a connector on the end of it. It's just a few wires encased in plastic, in a ribbon shaped flat cable. The ends of the wires have a small metal contact strip.

The connector on the motherboard is a ZIF connector.
Zero Insertion Force.
It is a rectangular shaped piece of plastic, that is composed of Two parts.

A smaller part that resembles a thin rail, at the top, and a thick block at the bottom.

The thinner part slides UP, (Towards the LCD screen),
OR,
it flips up. There are two different styles.

For the style that the thinner part slides up, it DOES NOT slide out!
It only slides up just a little, to unlock the Keyboard Cable. (1/8th inch approximately)

Then the Keyboard Cable slides out.
(Be SURE to note which way the Keyboard Cable goes in! Even if it is twisted, it MUST go back in the same position)

If you slide the ZIF connector completely apart, you will have broken it, and the repair is to replace the entire motherboard.

[ Also note which way all cables are routed through the laptop. They MUST go back in the same route, or you will not get the laptop back together ]

G) You will have to disconnect the Video Cable on the motherboard side, and the Wireless Module cables on the Bottom side of the laptop.

The Wireless Module wires are then carefully fed through the Palm Rest Cover, and laid aside. (They go up into the Display Assembly)

H) Perform one last check for any cables, then pop the Palm Rest Cover loose. (It has tabs formed on the outside edges, inside the cover. These snap into matching tabs on the Bottom Cover )

For additional questions please post in a Comment.

My wife's presario cq60 widescreen laptop has a power problem. For a period of time now, several weeks, on occasion it will simply go dark and nothing lights up. I remove the battery and power cord...


By go dark do you mean it turns off? If not, LED lights on the front of the laptop continue to stay on, but the screen goes dark, this could mean the backlight of the screen is going bad. It might be intermittent, but, a screen consists of two elements, the display itself, and the backlight which is what makes the image bright. If you bring it into a well lit area when it is dark and tilt the screen back and forth, you might see the faint image on the screen. Sadly, screen repairs are expensive, easily exceeding $300 most of the time. It is often a better idea to replace it rather than repair it.

2. Turn off the laptop and unplug it. Remove the main battery, DVD drive , Ac adapter and the hard drive. The hard drive is usually located in a slot on one side of the laptop. Remove the screw that holds the cover in place, then pull out the hard drive, screen sled.
3. Turn the laptop over and remove the screws on the bottom that hold the keyboard in place. Flip the laptop over, open it, then lift the keyboard up and out. Unplug the flexible ribbon cable that connects the keyboard to the motherboard.
4. Remove the screws that hold the laptop keyboard bezel and palm rest in place. Carefully pry loose any plastic snaps on the sides, then lift the bezel and palm rest up and out.
5. Unplug the Fujitsu LifeBook S2210 CPU Cooling Fan. Remove the screws that hold the heat sink and fan in place, then remove the entire unit from the laptop. Remove any thermal compound residue from the bottom of the heat sink and the CPU.
6. Apply a thin layer of thermal compound on the CPU, then replace the heat sink and cpu cooling fan. Replace the screws, plug the Fujitsu LifeBook S2210 Fan back in, then reassemble the laptop.

Laptop screen is black


i suspected your laptop screen is faulty because there's no problem when you connect it on external monitor. you might need to replace it. if it is under warranty there's no need to pay for the part.
