    What happens is that this computer only operates with the screen at a 120 degree angle from the keyboard. If you go to adjust the screen forward to a more upright position it shuts down and requires a ritual to get it to go again. You have to close the top, unplug the adapter, remove the battery, and reverse that order and open the laptopscreen to the most rear position and restart.

    An indication to me, that the Signal and/or Power cable, to the LCD screen is loose, or one of these cables may have a broken wire. One, or both of these cable's connectors have come loose. I would advise tightening them up. The connector for these cables is made up of two parts. A Male, and Female. They may have come loose from each other. To do this requires removing the top parts of the laptop, to gain access to these cables. One or more of these cables has a broken wire. Soldering, or replacing a broken wire requires some expertise. Do you wish to attempt this yourself? Tightening the connector/s, or fixing a possible broken wire? If so I can give you the Service Manual link, and guide you, just let me know.

This is going to be a little lengthy, and I thought I should advise you in advance.

This is the Service manual, for the Sony Vaio VGN-FJ series notebook PC's. (The Vaio VGN-FJ270/B is part of the VGN-FJ series)

Here you see the various Sony service manuals listed.
Go down to the eighth line. (Starts with VGN-A)
Look across until you come to - VGN-FJ.
Left-click on it.

[This is a PDF file download. Your computer has Adobe Reader on it which uses PDF files]

After you click on VGN-FJ you will see the first page of the manual within seconds. Watch the download progression bar, and let the file download all the way. I advise not looking through the service manual until it has downloaded all the way, or you may break the download connection.

I would also advise saving this service manual to your computer.
1.You won't have to download it again.
2.You can burn it off to CD disk to view anytime you want, and view on a different computer should you wish.
(You can also delete from the computer you downloaded it to, in order to save harddrive space)

To save a PDF file to your computer. (Ignore this if you already know)

Once the PDF file has FULLY downloaded, look up at the top header, and the icons.
You want to left-click on the Floppy Disk icon. This is the second icon from the left.
If you hover your mouse cursor over this icon, it will briefly reveal,
'Click to save this file to your computer or another location'

After you click on the Floppy Disk icon you will be presented with the
Save a copy... window.

At the bottom of the window is a box with - File name:, to the left.
In the box will be VGN-FJ
This may be all you need to find the file in the future. For me I do it different.
Take your mouse cursor, and place it after the J, in VGN-FJ
Left-click Twice.
Make one space with your spacebar.
Now type Vaio VGN-FJ Service Manual

For me it makes it easier to find on the computer, or on a CD disk.

If you do not have your downloads set to save to your My Documents folder, (Documents in Vista), this file will go to your desktop screen.

To change this, go up to the top of the Save a copy... window.
There you will see - Save in: and a box to the right. Left-click on the blue down arrow to the right of the box. In the drop down file 'tree', left-click on My Documents.

Now go down to the right, and click on Save.

Advice before you start working on your laptop:

1.Remove all electrical sources.
Remove the AC adapter if plugged in, (Charger), and the Battery.

2.Static electricity is an issue with computers. Static can fry out computer hardware components in a flash. You probably won't see it, or feel it. Your body carries Static.

Work on a table. A couch, bed, or directly on a carpet floor contains high amounts of Static.
I also advise wearing an ESD wrist s-trap. (Electro Static Discharge)
The s-trap goes around your wrist, and an exposed piece of metal strip contacts your wrist. This metal strip is connected to a cable, which ends in an alligator clip.

The alligator clip is connected to a good ground source. (I connect to an empty desktop computer case)
(A lot of computer related stores have ESD wrist s-traps)

Procedure to access the FPC cable, and LCD cable:

1.Remove the Keyboard (Page 8)

At the bottom of the laptop, is a single screw which must be removed first. Page 7 shows this screw.

At the top of the Keyboard, (Next to the LCD screen) are four detent buttons. {Above the F1 key, F5 key, F11 key, and the Insert/Pause key}

These are depressed on at a time. I use a plastic fingernail cleaner. Start from the left side. You may have to Gently ease up on the left side of the Keyboard, as you depress the four detent buttons. Most of the time once they're depressed, they stay that way.

The Keyboard is then tilted towards you. Use Care as there is a flat ribbon cable still connected to the Keyboard!

Photo 3 on Page 8 shows the Keyboard laid over. You are looking at the bottom of the Keyboard. The FPC cable is still attached. Photo 3 shows you the direction to ease the ends of the lock levers.

Remove the Keyboard, lay it aside.

2.Remove the Palm Rest (Page 10)
Remove the Optical Drive. (DVD drive) There is a screw located under the keyboard which has to be removed first. (Unless you have the 4th model. Then there are Two)
Page 9, Photo 3.

Turn the laptop over. There is one last single screw to remove before the Optical Drive can be removed. Page 7 shows it.

Now that the Optical Drive is removed, there are two screws in this area, which have to be removed for the Palm Rest.
Page 10, Photo 1

Follow photos 2, and 3 to remove the Main Power cable, and Touchpad cable. If you have the Felica follow Photo 4.

Now go to page 11 to finalize removing the Palm Rest.

Page 12 shows the FPC Main cable connection, and the LCD harness, (Cable), connection. These have to be tight.

The LCD Display Cable Is Most Likely Pinched Or Already Past the Pinching Point and Has Broken Solid Connection, causing the Short and shutdown when screen is moved or flexed...
The Hinge Area (Left Side)... Needs To Be Examined... And If No Short/Pinched/Frayed Cable In That Area, You Need To CHeck The Display Cable Where It Connects To The Back Of THe Screen... Reseat THe Ribbon Cable...

Brake lights wont shut off 2007 impala

The brake switch itself should be adjustable. Ones I know of can be screwed or moved in or out for proper adjustment. If not, is it possible you have a weak brake pedal spring? But, nah, not on an '07, I wouldn't think. If the switch is not adjustable, check closely the brake pedal for something not quite right. Good luck.

Darken the screen and either move the lid forward or backwards. Laptops have Liquid Crystal Screens and moving the lid backwards or forward will give the screen a different look.

If you need to adjust the brightness of the screen it is controlled by keys on your laptop. Most times to darken the screen you will have to hit the FN, CTRL or ALT key and hold it down while you hit the key that corresponds to the screen darken key. On some computers (even on my laptop) it will be the down arrow key, so i would press FN+the down arrow key. Remember to hold the first key down while you hit the next key. The icon used for most times to denote the brightness or darkness looks like a circular sun or a washer that goes on screws.

Haier 45 pint dehumidifier does not shut off when bucket is full. How do I adjust the float cup switch (forward or backward)?

If you want it to shut OFF before the tank is totally full, slide the float cup forward. if you want it to fill completely before shutting OFF, slide the float cup backward. Some folks prefer the half full, because the bucket is not as heavy to remove and empty, as it is when it's full.

Hope this helped you. Please let me know. Thanks.

Murray 22in throttle-free push mower

Throttle cable probably needs adjustment. If not adjusted properly it wont go to the shut off position. There is a clamp that should be on side of the engine, loosen the screw on the clamp, then move the cable-try pushing it forward or backward, but not more than 1/4 inch at a time, tighten after each adjustment. Engine is shut off while adjusting, once tightened crank the mower and see if that improves it. You will just have to try each direction until you find which way it needs to go.

Dell D610 Latop screen wont resume after it has been shut

it is possible that the latch is sticking. located under the lid.
try pressing the small button, with a small blunt screwdriver.
Failing this, adjust the settings in My Computer/Control Panel/Display settings or Similar. If they,re adjusted to hibernate/sleep/shut-down computer, when i close the lid.
this is where the problem will be. Try changing to Do-Nothing or similar.

Thankyou For Using Fixya.

Dell E196FP TCo99 Monitor screen problems

The screen colour changing is apparently an auto test procedure on the monitor and was prompted by a fault with the monitor not automatically shutting down when the computer is shut down. The settings on the monitor have been adjusted to rectify this and the problem is now gone.

Monitor Adjustment (hardware)

It is usually just a matter of forcing it back. You migh check if there are any kind of handles/knobs to loosen, but there usually isn't. Check if the screen should be lifted up (some bases are kind of telescopic) frmo the bottom position to losen it. Any chance of a picture of the side/back of the monitor?
