The top left corner of my screen is black, but when I press on the edge of the monitor the color comes back slightly, and there is a black blotchy line that almost looks like ink running between the blacked out screen and the remainder of the screen

The LCD is failing and it has either been impacted with something or the edges are leaking. When you press on it you are making a bad connection better. Replace it.

SOURCE: screen corner insensitivity

Screen drift is a common problem on Palms and there are many forums about it. First, make sure it is not your screen protector. This is a common culprit. Also, make sure ther is no dirt between the screen edges and the case. Running a folded piece of paper in between can clean it. I worked on a friends Palm with this problem and the solution was third party software called PowerDigi. Here is the link:

Unfortunately, this software is not free.

It sounds like your screen is going out and will probably need to be replaced soon.

SOURCE: black lines appeared on the screen

im sorry but it seems thats the screen had a dead pixel from when you bought it, the dead pixel has then since killed off the surounding pixels and they in turn have done the same. this sometimes forms a line but in some more unfortunate cases the screen can lose visual on both x and y axis's.
unfortuantly your manufaturers warrenty will not cover dead pixels as they are so common and there is a torrerance for them without doing harm, but some times dead pixels can spread.

hope this helps.

SOURCE: I have a black feather type line extending from

Hi,

This is a common problem on these sets. Have you tried a hard reset?

It would wipe out all the details, however this is the last resort for a customer. You could also try to soft reset the device by pulling the battery.

If the problem persists ( this problem was there when customer update the software ), you need to send the unit for repair.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

I have a dell inspiron 1501 laptop. My computer was working fine last night but i fell asleep and left it on over night. Wwhen i tried to reboot my screen stayed on until it got the welcome screen after...


blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,
if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on. To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard. Press the power button if the screen remains black.

Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue. Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue. Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.
Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.
Slide the battery latch to eject the battery. Pull the battery out of its compartment. Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard. Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.
Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector. Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place. Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective. If the external monitor works, the LCD screen could be broken. If the monitor doesn't work, the motherboard or video card might need to be replaced.

My averatec laptop will only power on to a black screen but it still sounds like its booting


1) Laptop on use a flashlight, and shine it at the LCD screen. Shine at various angles.
Do you see faint images?

2) You can also plug in a VGA monitor to the back of the laptop, (Laptop OFF, monitor off), and toggle over.

(It can be a VGA monitor that looks like a small TV {CRT}, or an LCD flat screen that has a VGA cable attached)

Plug the VGA monitor's cable into the blue VGA port on the left side, of the Avertec 3200 Notebook PC.
(Example of VGA connectors,

http://en.wikipedia.org/wiki/VGA_connector

Turn the VGA monitor on. Give it time to 'come to life'.
Turn the laptop on.

Are there graphics on the external monitor? If not press, and hold down on the Fn key, (Blue Fn next to the CTRL key), then tap the F2 key.

(The F2 key is the toggle over key for an external monitor. You can use the laptops LCD screen, or it's screen, and an external monitor)

Graphics show on the external monitor? Your graphics chip is good.

Problem is with the screen Inverter, or the Backlight.

An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is the additional light source.

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

A screen Inverter is used to convert the electricity from the laptop, for the LCD screen, and the Backlight.

90 percent of the time the fault is the screen Inverter.

The Display Assembly essentially is;

1) Top cover of the laptop. (Display Cover)
2) LCD screen
3) Display Bezel. (Thin plastic frame in front of the LCD screen, and surrounds the LCD screen)
4) Inverter
5) Backlight
6) LCD screen frame

With the Display Bezel removed, the screen Inverter should be at the bottom/front.

This is an example of a screen Inverter for an Averatec 3200 from a quick search,

http://www.laptopaid.com/averatec-3200-lcd-inverter-board-76-030105-02-tested-1629.html

I haven't worked on an Averatec 3200 Notebook PC before. I have worked on 100's of other laptops.
The sequence for removing the Display Bezel follows a pretty standard approach.

Looking at the Display Bezel I see four screw covers. (I'm looking at a PDF Users Guide)

One at the top Right corner, one at the top Left corner, one at the bottom Left corner, and one at the bottom Right corner.

These screw covers made of a rubber-like material. (Synthetic rubber) They are slightly rounded on the top. They have a type of rubber cement that holds them in place.

I use a computer pick to gently pry them off. If you carefully pry each screw cover off, and set them down sticky side up, (Screw side), you can usually reuse them again.

Screw covers (4) removed, use a Philips head screwdriver, and remove all 4 screws.

The Display Bezel will still be held in place. It has plastic tabs on the outside edges that snap into the Display Cover. (Top cover of laptop)

A fingertip is used on the INSIDE edge of the Display Bezel, next to the LCD screen.
(WATCH your fingernails against the LCD screen)

The fingertip raises the Middle/Inside edge of the Display Bezel, just slightly.
Now use another fingertip on the opposite side. Raise the Middle/Inside edge.

The Display bezel should start 'popping' out. (As the plastic tabs release they make a popping, or snapping sound)

To illustrate this technique further,

http://www.insidemylaptop.com/replace-damaged-lcd-screen-dell-latitude-e5400-e5500-laptop/

http://www.insidemylaptop.com/replace-lcd-screen-inverter-dell-inspiron-1525-laptop/

(One more, to show you where I believe the screen Inverter is for the Averatec 3200 Notebook PC, and what an average screen Inverter circuit board looks like,

http://www.insidemylaptop.com/remove-screen-inverter-dell-studio-1737-1735-laptops/

When the Display Bezel is loose, you slide it to one side a little to ease it around, and off, of the cover latch.

The cable connectors going to the screen Inverter are shaped differently from each other, so that when you go to reinstall them, there is no chance of mixing them up.

With the tools you have available, I would replace the screen Inverter ($7 plus shipping), and see if this repairs the problem.

If not the problem is the Backlight. Most of the time you have to buy the LCD screen, as the Backlight is an integral part of it, and should be replaced by a professional.

[ An LCD screen is composed of layers. The layers are held together in the correct alignment by the LCD screen frame.
This alignment MUST be aligned as it was from the factory.

This gives you an example of replacing a Backlight,

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

Make a mistake here, and you can throw your LCD screen in the trash ]

How to use buttons on front of Monitor for vertical Horizontal settings


Oldie, The first thing to do is set the monitor resolution, color depth and monitor refresh rate to what you want then adjust the monitor accordingly. Adjust resolution, color depth and refresh rate for Windows 2000/XP: -Right click any clear spot on your desktop and select properties from the menu that appears. -From the Display Properties box that appears click on the Settings tab. -In the screen resolution section (lower left corner) experiment with the resolutions and see what you like. -The color quality box should be set to the highest (most colors) color setting listed. -Click on the advanced button in the lower right corner. -In the next window click on the monitor tab. -Typically you would want to set it at 70 Hertz or better. The higher the setting the less flicker you will notice, however, there is always a trade off. I would start with 70 Hertz and gradually move up; at some point your monitor will reach a setting it can?t support. If the screen blanks out Windows will reset back to the previous settings as long as you don?t hit any keys. -click the OK button twice. More to follow?.
