    Hi there ego,

    You didn't mention in your post, so I need to ask: What is your level of expertise in the diagnosis and repair of Notebook Computers?

    I ask because after thirty years of programming in thirteen languages, being an expert in the operation, maintenance, diagnosis and repair of data processing machines ranging from mainframes to PC's, I have only the most cursory knowledge of the problems specific to laptops and notebooks.

    They require additional training. Often training is geared to specific makes and product lines.

    That knowledge I do have was gained by repairing my own company's laptops. The first thing I learned was this was the training I mentioned was absolutely necessary.

    Experts
    here volunteer their services. Their only compensation may be the
    satisfaction of helping others and pride in the ratings they receive.

    They freely give you, The Asker, the benefit of decades of experience for exactly zero pay.
    Some people come here looking for a simple fix (press the the Ctrl-F key and all your problems will be solved) when one simply does not exist. Magic 'One Liner' solutions are rare.

    And sometimes in the best interests of the Asker, the best advice is to take your equipment to a qualified technician.

    This advice is given when there is ether a danger of injury or death to an untrained person attempting repair or an attempt to make repairs will result in permanently damaging the equipment. I see that to be the case here.

    So I ask you again, what is your level of expertise?

    If it is anything less than A+ certification with a backround in laptops, I would
    like for you to reconsider the 'Inappropriate' rating you gave Jazzy.

    This
    rating is worst type of insult. It should
    only be used in the rare case that the advice you received was totally
    irrelevant to the problem or outrightly profane in which case should be
    reported as abuse.

    Neither one of these was the case here. Your rating
    of Inappropriate is the only inappropriate response appearing in this
    thread.

    At the very least, he earned a Helpful.

    If you had made the mistake of opening your machine up, then tried to reassemble it after you realized you were in too deep, I guarantee you would have rated his advice a FixYa retroactively in exchange for not having done it.

    You
    blasted a lot of hard work, reduced his rank and the smeared the reputation of someone that was
    not only trying to help you, but was doing it for free. Doesn't exactly make you feel all warm and fuzzy, does it?. I would think this is something you would want to
    rectify.

    Also keep in mind that Experts here pick you, not the
    other way around. An Asker who doles out IA's for helpful advice
    without any interaction, even as a mistake (which I'm hoping it must
    be)
    is unlikely to be helped by a second Expert.

    That includes future problems too. It depends on you either getting that IA removed
    or improved. Until then, you have already received the only help you are likely to
    get.

    It's a Karma thing. I don't make the rules, I'm just letting you
    know you shot yourself in the foot.

    You know how to fix it.
    You know
    you should fix it.
    So take 15 seconds and Fix it.
    The balls in your court.
    Good luck and have a nice holiday.

This note is primarily in response to dank84:

The "backlight" is built-in to the display panel itself, so there is no way to replace the lamp itself. In most cases, it is the "ballast" that has gone bad. This is a small board either on the side or bottom ofhte top case. There are a number of reasons for this to fail. Many times a bad battery or weak charge can cause extra current draw that pops a soldered fuse on the board. Other times, capacitors fail. Still others, the onboard transformers that convert the "low" voltages to "high" voltages required for the flouresceent lamp to fire go bad.

The bottom line is that this is not a consumer type of repair in most cases. Depending upon the age of the laptop and the skills of the local servicer, this may not be an econimical repair.

You will need to get it checked at a shop because you might have a short that is causing too much power to go to fluorescent lamps and is making them die.

Backlight will not turn on


It might be the Cold Cathode Fluorescent Lamp.

I was thinking along the lines that the lid switch may be the problem, but this would turn the display off also.
(Where is the lid switch? Dunno. Sometimes a little post that sticks out of the Switch Cover, or is a hidden magnetic switch, and usually located near the Touchpad)

A note on the CCFL. It has Mercury vapor on it, just like it's 'bigger cousins'. (Home and business size Fluorescent tubes)

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.

Yes. Will break VERY easy, and contains poisonous Mercury.
You MAY opt to just replace the LCD screen.

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


The screen Inverter, and LCD screen are a MATCHED unit.
Usually when the screen Inverter proves to be bad, the Backlight is not far behind. (And vice-versa)

I usually do not post CCFL replacement, due to the Mercury poison hazard.

Note*
An LCD screen is composed of layers. These layers are aligned by the factory, and are kept in alignment by the metal Screen Frame, which surrounds them.

You MUST keep the layers aligned in the factory set position, when replacing a CCFL. (Or CCFL's if it uses two of them)
Breaking the CCFL bulb is not the only thing to watch out for.

Mohammad,

Toshiba Satellite P100 screen Inverter replacement;

1) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-P105-P100/remove-lcd-screen-inverter-1.htm

(You can click on any photo to enlarge it. At the top, and bottom of the page are the page numbers. They are in white; Page1 :: Page2 :: Find another model )

2) Primer:
An LCD screen cannot produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight (Present technology) is a CCFL, or a series of LED lights.
The Toshiba Satellite P100 series of Notebook PC's uses a CCFL.

Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

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 )

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

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

As previously stated in a Clarification, 90 PERCENT OF THE TIME the fault is the screen Inverter.

http://www.zkarlo.com/selected-zkarlo-part/inverter-board-p907.php

HOWEVER, the Backlight bulb is located inside the Screen Frame, of the LCD display assembly.

An LCD screen is composed of layers. These layers are held in a specific pattern, by the LCD screen frame.

This is a thin metal frame which surrounds the LCD screen layers, and has Philips head screws which hold the frame together.

NOTE*
The procedure is fairly intricate.

No screen display


Your LCD inverter circuit or Backlight lamp may have died. The Backlight lamp is a CCl (Cold Cathode Lamp) closely resembling a thin fluorescent light bulb.
If you can replace this lamp, the typical cost for this component is $9-$15.

First thing to try is to plug in a standard (RGB analog) monitor into the system's 15-pin external monitor port to see if the system is booting to MSWindows (or not).
If the OS is failing to boot, at least the external monitor may allow you see what the ROM BIOS is doing, and possibly run BIOS-based system diagnostic software.
If the OS is booting properly, you can use the notebook PC with the external monitor (as a workaround), until you can repair the console screen, or replace the computer entirely.
If you are able to access the system via the external monitor, you may want to take the opportunity to backup any important data (iTune downloads/income tax forms/original manuscripts for novellas/MRI scans,etc.) on the Toshiba A135 to an external hard drive, large flash drive or CD-RW discs.

When i turn on my laptop the screen just starts flashing.i only bought the laptop 3 months ago


If purchased as new, it should still be under warranty; don't delay though. If it isn't and there is no sign of video when this is happening, the driver circuitry in the display has probably failed. If there is video, then it can be either the fluorescent backlight lamp itself or the inverter for it.

Screen remains dark


1.Try to increase the Brightness of the LCD screen.
Press the Fn key, and tap the F7 key.

If this does not increase brightness, or dims later on, I suggest you have a bad Backlight Lamp, (Bulb), or Inverter.

Backlight's are usually the first to go, then the Inverter. However,...although Backlight's are cheaper in cost, they are much harder to replace.

The Backlight is located in the side of the LCD screen itself.
An LCD screen cannot give off enough backlighting by itself. It needs an external source such as a Backlight Lamp.

The Backlight Lamp is a CCFL. Cold Cathode Fluorescent Lamp. (Resembles a real small fluorescent tube)

To briefly illustrate where the average Backlight is located, and what an average Backlight looks like,

http://www.laptopparts101.com/screen-backlight-ccfl-lamp/

This shows you how to access the Inverter, ( Board), and what it looks like for the Toshiba Satellite M35X series of laptops,

http://www.irisvista.com/tech/laptops/ToshibaM35X/Satellite-M35X-display-1.htm

[Click on Page 2:: at the bottom of this page. Step 9 and 10 illustrate. You can click on the photo to enlarge]

The Inverter supplies power to the LCD screen, and to the Backlight Lamp.

To access the Backlight Lamp, as you can see, you have to carefully separate one side of the LCD screen, itself. The LCD screen is composed of layers. One mistake here, and you are buying an LCD screen. Average cost? $125 to $225. Depends on where you buy it.

Access to the Inverter, (Board), is much simpler.

BEFORE anyone should attempt this, there are guidelines that should be adhered to:

1.ALL electrical sources should be removed. Remove the AC adapter, (Charger), and the Battery.

2.The tech should wear an ESD wrist s-trap, and have the alligator clip attached to a good ground source.
(Electro Static Discharge. Your body carries Static electricity. Static can burn out the hardware components in a computer, in a flash. You probably won't see it, or feel it.

POOF, and you'll never know why your computer doesn't work anymore!
Wearing a cheap $6 ESD wrist s-trap, and having it connected to a good ground source prevents this. I connect to an empty desktop computer case)

3.Have a multi-compartment, clean container, that you can label each compartment, for the various screws.
Some screws look Very much alike. You install the wrong screw, and you'll strip the threads out in the screw hole, or the screw. {Or it will be stuck in halfway, and twist off when you take it out. All sorts of fun? stuff}

4.If you need to, take notes, make drawings as you disassemble. May make it easier when you go to re-assemble. You may want to use a digital camera, and good lighting.

Monitor keeps shutting off after a few seconds- hp dv4000notebook


You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

How to replace an inverter in an Acer Aspire 4315? I can't find you the exact manual at the moment. HOWEVER, I can give you a link to manuals that are close to the Acer Aspire 4000 Series laptops.

I have found through the years, that many laptop makes and models, are very similar, when it comes to disassembly, of the entire laptop, or just the LCD screen. These manuals are for various models of Acer Aspire laptops,

http://www.notebook-manuals.com/manuals/ACER/Aspire
And,

Look online for Screen Inverter and also Backlight Lamp, for your Acre Aspire. There are many places that sell them. (Average price for the lamp, ranges from $8.99 to $14.99, or so)
