What is a "LCD Inverter" on a laptop ? And what happens if it stops working ?
89506
Small board/chip that inverts power (DC to AC) to the LCD screen.  If it stops working, your screen goes black.  Depending on your skill & confidence level, not too expensive to replace.  Check out www.laptopking.com for parts.

As well as the other answers...\n It sounds like one or more keys on the laptop are being\nshorted out, and the problem is getting worse. I have had this\nhappen on a few keyboards, for various reasons. \n If you can go to the Compaq website and find how to remove the keyboard, often just releasing two or more slid buttons \nat top or botom, or sliding keyboard up or down, and gently lifting, to expose a ribbon cable, which you usually snap out a wedge release and pull out cable, etc.\n THEN, you can examine the keyboard, or plug in an external\nkeyboard, without interference from the "suspect" keyboard.\nSince the touchpad, and the self-suspend mode are also\nmalfunctioning ( these may be keyboard controlled ! ), there\nmay be a larger problem with the I/O connctor from the laptop top, to the motherboard. I suspect mechanical problems. Could the keyboard have been squished, and had buttons pressed too hard, which had caused contacts to \ntouch at random? There is a number of keyboard -design peculiarities I have run across with DRY contamination- whereby the traces on the circuitboard itself, particularly\nsilver painted ( probably multi process electroplating )\nor black carbon paint traces, will produce a fine powder,\nwhich drifts across the circuitboard, gradually shorting the\ntraces, causing random inputs. This dry silver, or black powder can be virtually invisible to the naked eye, and must\nbe cleaned off with a damp cloth, gently... It is the exact same powder that shorts out many remote controls for TV etc. and shorts out many game pads...\n Based on the behaviour of the keyboard, and the fact that nothing is wet, this would be my first bet.\n Laptop keyboards are "one-of a-kind " and there are no rules, as manufacturers boldly try every new idea to make them thinner and lighter... \n I dont think that the keys themselves are at fault, and that you have to look at the actual traces UNDER the keys...\nIt is a bit difficult, and you must proceed slowly and carefully...\n With ordinary Desktop keyboards, my advice on this ANSWER \nforum, is as follows... and some of the same advice still applies...\n\nMost of the answers already have some merit.\nI have a couple of older keyboards that I really like\nthe key action, the placement, and the key sizes.\n(the backspace is two keys wide, The ENTER is two buttons wide and two buttons tall, such as an IBM Selectric, etc.) \n There are about 5 different kinds of keyboard construction.\nThere are also dozens of rare models, and depending on what\nkind it is, you either can take it apart fairly easily,\nor you should not even open the case! One type of IBM board\nhas a coil spring under each key with a rocker arm. The spring is like the one in a ball point pen, and all are loaded, so that if you take the top and bottom halves apart, you end up with hundreds of springs and parts flying all over the room.\n However. 99% of keyboards are not as complicated. Many keyboards have screws on the back. If so you can use a phillips screwdriver (star) and remove them. The top and bottom of the keyboard usually have snaps that generally open from the front first, and hinge on the back. Gently pop the two halves.  If there are no screws then the halves just pop.\nUse a flat screwdriver to pop along the seams. Every couple of inches there will be a snap.\n You will generally see one of 2 basic types today.\nThere will be a green cirucuit board with copper traces on it, covered by a rubber sheet with buttons in it, or you will find each key has a tiny rubber button -- open the keyboard upside down, so the keys and buttons are held\nin place...\nNote that the SPACE bar, the ENTER and other wide keys may have two buttons, and a wire or plastic bar underneath that has an arm on each end to keep the wide key from wobbling from side to side. These vary quite a bit in how they snap in place. You have to figure out how to unsnap them - usually by springing in the two ends which ar

The backlight invertor has burned out, this is replacable and the part will cost about $30 to $60 plus about an hour labor to have it installed. The actual screen is fine, and the invertor is a small board that is located inside the screen casing. I would not recromend replacing this yourself unless you have experience doing so, the invertor can carry extreamly high voltage, most repair shops should be able to do this for you.

Every item sold has to be fused...make sure you checked both the primary and secondary of the power supply first before assuming the laptop has a blown fuse.\n\nGood luck on your quest.

This is a permanent damage that has happened to you LCD screen. \n\nThe problem might be dead or lit pixels:\nOccasionally the individual transistors responsible for carrying current to a pixel either short out or remain open resulting in what is called a dead pixel. \n\nA "lit" pixel is one that appears as one of several randomly placed white, red, blue or green pixel elements on a dark background, or you may have a "missing" pixel which shows up as a black dot on a light colored background.\n\nThis can only be replaced by the manufacturer as usually this kind of problem is not repairable in India.\n\nIf your laptop is under waranty period your lucky!

Easy, have them buy you a new monitor.  LCDs can have problems if too much pressure is applied.

you need to describe what you mean by "small" better.\nis it too small vertically, horizontally, or both?\nAlso, how good is your electronics background?\nDo you know how to discharge the CRT and large capacitors so you don't get zapped with 330 to 10,000 volts while attempting to repair it?\nYou also need to define "wavy" better.\nWith the tin amount of information you have given though, it sounds like the power supply is failing, but in which part is impossible to say.

I would say you contact DELL, coz it could be a safety hazard issue here. They might even offer you a replacement in this case. Just try ur luck.

I have the same issue with mine, I am not sure of what can be done yet, as I have taken mine apart and checked all the connections / cables pertaining this this LCD problem. However,Your laptop can still work with an external monitor. So for a short term fix you need to acquire another monitor / LCD Monitors are reasonably priced now.\nUntil we find the real fix....

There could be issue with the Display. \n\nTry performing Power Drain. \n\nHere are the steps for Power Drain:\n\n1. Disconnect the AC Adapter. \n2. Remove the Battery.\n3. Hold the Power button down for 30 seconds to 1 minute. \n4. Reconnect the AC adapter and do NOT connect the battery now. \n5. Turn on the Notebook power. If the problem persists, please disconnect the AC adapter and connect the battery alone. Now check it again.\n\nTry reinstalling the Display drivers. Also, you can try updating the BIOS version. If the issue persists then, there is sure issue with the display.

Most laptops have a function key combination that enables the video to be displayed on a) the monitor only  b) external device or c) both simultaneously. First look for a function key on your laptop keyboard (usually one left of the Windows key), then look for a function key along the top row of F1 - F10/11/12 keys and look for an icon that looks display related, or it may say CRT/LCD. Press the Fn key then the CRT/LCD key (on my keyboard, a Dell Inspiron, it is on the F8 key) and wait a few seconds. Look at your screen and the projector screen to see what happens. If it displays you're set. If not press the key combination again. \n\nYou should verify that the cables from the projector are properly connected first obviously.\n\nOn the codec question, if the video is playing properly on your computer screen then it is not a codec issue. Codec has nothing to do with sending video/audio signal to an external monitor or projector, so you should be fine on that front.\n\nGood luck.

I used to have a Toshiba and it crashed and nobody can fix it. My suggestion: dump it and get a Gateway.

(If it's laptop) you just have to charge it. If that doesn't work, replace the charger. If that doesn't work too, replace the battery. If nothing works, buy a new computer.

If the laptop or the battery are powering up when the adapter is plugged in then, the LED may be faulty.  If the laptop does not power up or the battery doesnot charge then the adapter is definitely faulty.  Also try plugging the adapter into different wall socket.  If your adapter has a detachable "kettle lead" with plug, then try chaning this lead.\n\nBattery Wizard\nhttp://www.ComputerBatteries.co.uk

The backlight of a laptop is a fluorescent panel driven by a power supply that takes battery power and generates a higher voltage suitable to make the panel light up and vary the light output.\n\nA rough guess is you damaged the fluorescent panel, it's power supply has blown up and since a lot of manufacturers have the power supply up in the lid of the laptop the flexible cable has flexed once too often and broken a wire to the power supply.
