Averatec 3200 Blank Screen

Reload the software,.

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,

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,

(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,

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

If you are getting the logo in the beginning that means screen is fine. Reset defaults for BIOS and try booting your computer with the help of disk.

Seems to me the inverter is gone if you replace the inverter it will work like a charm

Look very closely at the screen when its on, see if you can see a faint image in which case the ccfl tube in the screen will be dead. Also try the laptop on an external monitor.
Otherwise if you know what your doing, remove the battery, hard drive, optical drive, all but one stick of ram, modem/wireless card and try again. There is a small chance it will be the cpu or motherboard.

Try reseating the memory one stick at a time in each slot one at a time and turn on the laptop after each stick reinsertion.

Yes..most probably its HDD. Remove the hrddisk and try booting. If it displays, no HDD.then the prob lies with HDD.

If cd pops in and out it is defective . This can stop unit from booting.

Click on start right mouse click on My Computer your in System control...go to hardware to device look at the CD or what Windows is emulating then trouble shoot the hardware.

The LCD needs to be replaced. As for the D/C Jack its the sort of laptop an engineer would have to play by ear. Or in otherwords work it out as they go along. Try removing all of the screws that you can find and be careful that you know where the screws go back afterwards. You might need to flick the hinge covers off to access the rest of the laptop. They also tend to have plastic clips all around them.
