Is this a reference to a screen Inverter for a Dell Inspiron 2200 Notebook PC?
If so the Inverter is not an ignitor. It is a converter.
Converts electricity from the laptop for the LCD screen, and Backlight.
This is Dell Support > Inspiron 2200 Notebook PC > Service Manual,
http://support.dell.com/support/edocs/systems/ins2200/en/SM/index.htmClick on Display.
The screen Inverter is located behind the Display Bezel, and at the bottom of the LCD screen.
Just to take a look at it's location scroll down to step 12. Lift the display assembly out of the computer base.
The LCD screen is pointed out by the number 4.
At the bottom of the LCD screen is an Orange rectangle. This is part of the screen Inverter circuit board.
This shows the screen Inverter in more detail,
http://www.batterycentury.com/dell-inspiron-2200-inverter-p-185186.htmlTips from me. Expanding on what Dell Support states, and doesn't state.
1) Remove ALL power from the laptop. Remove the AC adapter (Charger) and Battery.
2) I would lay a clean soft towel on the table you're working on, and the laptop on the towel.
Helps to prevent scratching the laptop, and the table.
3) Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
If no multi-compartment container is available you can substitute with a clean egg carton.
Label each egg holder.
SOME screws look VERY similar to other screws. Do NOT mix them up.
4) Laptop display opened as far as it will go.
The first screw you remove (Philips head screw) is for the Ground wire.
Grounds the Display Assembly to the body of the laptop.
(Steps 1 , 2, and 3)
5) Next you remove an Electro Magnetic Interference shield.
Four Philips head screws. The end of the EMI shield is then lifted up, on the side opposite of the LCD screen.
The end that is away the LCD screen.
This is because there are two tabs on the LCD screen side.
(Steps 4 and 5. The FRONT of the EMI shield is towards you. Towards the Front of the laptop)
6) Disconnect the white wire from the Mini PCI Card.
(Step 6)
7) Close the display. Turn the laptop over.
In Step 8 you're shown two Philips head screws to remove. If you look at the body of the laptop close to the screw holes, you will see the letter D.
Represents Display.
(Steps 7 and 8)
8) I hold my arm across the two holes when turning the laptop over. Hand on one hole, and arm covers the other hole. When the laptop is close to the table slowly slide your hand back. This should let one screw fall to the table. Then slowly move your arm, and let the other screw drop.
A lot better than picking up screws that bounced off the table onto the floor.
There are two Philips head screws to remove from the back of the laptop.
These are shown in Step 9. The letter D is near each screw on the back.
(Step 9)
Once you start removing one of these screws, the Display Assembly becomes loose.
Support the Display Assembly with one hand while removing the screw/s.
Failure to support the Display Assembly could result in damage to the Display Cable, and Mini PCI cable.
9) In Step 10 you are directed to pull up on a pull tab for the Display Cable.
The Display Cable is a FFC.
Flat Flex Cable.
It ends in a small white rectangular connector, which is plugged into the motherboard.
The 'pull tab' is a piece of cloth, that is attached to the FFC's connector.
I gently ease up on the pull tab, WHILE easing up one end of the white connector.
I then ease up on the other end.
This is a gentle operation. Do not yank up on the pull tab.
10) In Step 11 you are directed to remove the Mini PCI Card wire FROM the body of the laptop.
Observe the way the wire is routed through the laptop, and the clips. The cable is threaded through the body of the laptop.
You MUST reroute the wire back into the same routing, when reinstalling.
(You may wish to make notes, and a drawing, and perhaps a digital photo or two)
11) Lift the Display Assmebly up, and out. Lay it carefully on it's back on the towel.
(LCD screen side up)
12) Display Bezel
The Display Bezel is the thin plastic frame in front of the LCD screen.
Resembles a picture frame.
It is held onto the Display Cover, (Plastic top cover of laptop), with tabs, and 6 Philips head screws.
These tabs are extruded from the bezel itself, so they are PLASTIC. They are on the outside edge of the Display Bezel.
There are 4 screws across the Top, and a 1 screw in EACH bottom corner.
These screws have a rubber type of cover over them.
The Screw Cover is stuck to the head of the screw with a type of rubber cement.
This means if you gently pry the screw cover off, and set it aside, there is a Good chance you can reuse it again. Stick it back in place when you reassemble.
I use a computer pick. Looks like a very thin ice pick. Perhaps you have a similar tool of some sort.
(You can also use a small flat tip Jewelers screwdriver)
Yes, lots of fun. The Screw Covers like to stick to your fingers when you go to lay them aside. They also stick to the tool.
Remove the 6 Display Bezel screws.
As stated the Display Bezel has tabs, or protrusions going around it's outside edge. These tabs snap into place when the Display Bezel is installed.
They also snap, or pop, when the Display Bezel is being removed.
On the Bottom side of the Display Bezel, AND in the Middle, ease the Inside edge of the Display Bezel up a little with a fingertip. Use caution as you fingernail will be next to the LCD screen.
(This is why tech's wear a type of rubber glove. Helps to protect the laptop)
Once the inside/middle edge of the bottom of the Display Bezel is lifted up a little, ease another fingertip under. Move this fingertip towards one side until the tabs pop.
Ease your fingertip towards the other side.
With the bottom of the Display Bezel loose, go to one side. Left, or Right doesn't matter.
Start in the middle of the Display Bezel on the side, and ease a fingertip under the frame of the Display Bezel. Loosen it's tabs.
Do the same for the other side.
{ The Display Bezel is made of space-age plastic. Pretty TOUGH stuff. Use care when removing the
Display Bezel, but don't freak out when you hear the snapping sound of the tabs releasing. It will sound as though you are breaking it, but you aren't }
Note the Latch at the top. The Display Bezel has a slot that the Latch goes through.
The Display Bezel is slid to one side to ease the Display Bezel off, and away from the Latch.
13) You are now looking at the screen Inverter at the bottom of the LCD screen.
{It isn't part of the LCD screen. It just is mounted Under the LCD screen}
Note the wires that go to the screen Inverter, and their connectors.
Note that they are different from each other. You can't mix them up.
