The backlight is incorporated into the lcd panel itself. it's not a stand-alone part so the whole lcd display needs to be replaced. In our service department, this part will cost you over $350 Canadian dollars. With the age of the laptop taken into consideration, it may be better in the long run to connect the laptop to an external monitor and look at a new laptop. You can remove the display panel to do this if you like, but be aware that the wireless antennas are in the display panel, so you will have to remove the antenna wires from the display panel or use a usb wireless card.

If you want to get a part number and price, contact acer directly.

Hope this helps :)

Acer notbook black screen

Acer Aspire 5732Z series of Notebook PC?

Need to test whether the problem is;
A) Graphics chipset,
B) Video Cable,
C) Inside the Display Assembly

Inside the Display Assembly problem could be;
A) Screen Inverter
B) CCFL Backlight
C) LCD screen

1) CCFL Backlight:
CCFL stands for Cold Cathode Fluorescent Lamp. (Bulb)
Similar to Fluorescent lighting used in homes, and businesses; but on a MUCH smaller scale.

According to searches for an LCD screen, the Aspire 5732Z series of Notebook PC; uses one single CCFL for a Backlight.

One example,

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.

The CCFL contains MERCURY, just like it's larger 'cousins' used in homes, and businesses.

Mercury is a POISON. The bulb breaks EASILY.
If a CCFL is the problem, I STRONGLY recommend letting a professional change the CCFL out, OR just replace the LCD screen as a unit.
It contains the CCFL backlight,

View the last 8 photos.

Use a flashlight, and shine it at the LCD screen at various angles.
If you can make out graphics on the LCD screen, the Backlight is bad; or the screen Inverter.
90 PERCENT OF THE TIME the fault can be attributed to a bad screen Inverter.

2) Graphics chipset:
Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the back of the laptop.
The VGA port is on the Back of the laptop, and next to the Ethernet port.
[ Which is right next to the DC Power Jack (DC_IN), that you plug the AC adapter (Charger) into ]

This is an example of a VGA cable, and VGA connector (Port),

Scroll down for the VGA cable example. Note that color of connector does not matter. It is usually Blue in color, though.

You can use a CRT type of monitor, (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable.

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.

You have at least 3 display options available;
A) Internal monitor of laptop ONLY
B) Internal monitor of laptop AND external VGA monitor
C) External VGA monitor ONLY

Press, and hold the Fn key down.
(Bottom row of Keyboard, second key from left)
At the same time tap the F5 key once.
(The F5 key is the Display Toggle-Over key)
Still no?
Hold the Fn key down again, and tap once more on the F5 key.

No display on the external VGA monitor indicates a bad graphics chipset. More than likely the problem would actually be the mounting, of graphics chipset TO motherboard.
It is soldered directly to the motherboard using a BGA surface mount. (Ball Grid Array)

I doubt you have a graphics chipset problem, but this flowchart method entails that; and no 'stone should be left unturned'.

It would 'bite' if you tried diagnosing without checking the graphics chipset, and replaced video cable, screen Inverter, and LCD screen; only to find you needed repair on the graphics chipset mounting to motherboard; or replace motherboard.

3) Video Cable:
This is an example of the Video Cable. Acer deems it the LCD Cable, and that's what we will refer to it as also,

The long White connector at Top, plugs into the motherboard, in an area to the Top/Left of the Keyboard.
It then routes under the left Hinge, and up into the Display Assembly.

The smaller White connector below it plugs into the screen Inverter.
The LCD cable then connects to the back of the LCD screen, with the large connector shown to the Left side.

The small connector below it plugs into the Camera.

Just from normal repeated opening, and closing of the laptop; the LCD cable may become pinched.
This can cause pulling on it, and result in loose connections at motherboard side; and/or screen Inverter, and/or LCD screen side.

Could also cause damage to the LCD cable.
Stretched/Broken wires.
If the sheath of the LCD cable looks to be damaged, so may be the tiny wires inside the LCD cable.

I will include a link to a free Service Manual, for the Aspire 5732Z series of Notebook PC. The above link, and other pictorial guides; are more for you to get a 'hands on' look, besides just looking at a Service Manual.

Here the repair is to Physically see, if you can plug those connections of the LCD cable, in tighter.
Visual inspection alone will NOT do.

Tried to plug the connections in tighter, and does not cure problem?
Then the LCD cable is to be removed, and a continuity test performed on ALL wires in the LCD cable; with a multimeter set to OHM's. (1K)

Or perhaps take the LCD cable down to the nearest small computer shop, and have the resident tech check it for continuity.
Should only be a couple of bucks.

You MUST rule out the LCD cable before going on. Some may feel with the low cost of the cable, they may just replace it.
Parts changing I know, and not professional; but to each their own until you learn.

4) LCD cable checks out it's time for the screen Inverter.
The screen Inverter is a small circuit board, that converts the power, (Electricity) of the laptop; for the LCD screen, and CCFL backlight.

To test requires a sensitive multimeter. Read fairly expensive.

The plastic frame in front of the LCD screen is the Display Bezel.
Acer? LCD Bezel.
The screen Inverter is located behind the LCD Bezel, and mounted towards the bottom of the LCD screen.

Due to;
A) Non-accessibility of a sensitive multimeter
B) Ease of accessibility of replacing
C) Low cost

,many decide to just replace the screen Inverter.
Again parts changing, but IMHO is justified this time.

[No. You do not want to drag the partially disassembled laptop, down to the nearest computer shop.

A) No tech really wants to come in on someone else's repair, and pardon me; but really not after a non-tech.
Liability issues are also involved.

B) Judge JUST one hour of their service rate, compared to the price of a screen Inverter ]

5) Screen Inverter checks out? (Replaced)
Then the problem is the LCD screen.

Service Manual,

Go to the paragraph that starts with Aspire 1200. (1200 in Blue)
Drop down to the 9th line. (5720 in Blue)
Scroll across, click on the blue - 5732Z

[Ignore if you are aware;
This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
(I would recommend upgrading to the newest version, though)

After you click on the file name (5732Z) it may take up to 30 seconds, before the first page comes up ]

How do i find hotkeys on acer aspire 5515 laptop

The Hotkeys are;

1) Fn (Function Key) + F1 = Hotkey Help; Displays help on Hotkeys

To go on anyway;

2) Fn + F2 = launches Acer eSettings Management in Acer Empowering Technology.

3) Fn + F3 = Launches Acer ePower Management in Acer Empowering Technology.

4) Fn + F4 = Puts the computer in Sleep Mode

5) Fn + F5 = Toggle the laptop from it's monitor to an external monitor, or use both.

6) Fn + F6 = Screen Blank > Turns the Display Backlight off to save power. Press any key to return.

7) Fn + F7 = Touchpad toggle > Turns the internal Touchpad on and off.

8) Fn + F8 = Speaker toggle> Turns the speakers on and off

9) Fn + Right Hand Triangle > Brightens the LCD screen

10) Fn + Left Hand Triangle > Decreases the LCD screen brightness

Acer Aspire 5515 Service Manual ( Free)

Go down to the second Aspire heading.
The one that starts with Aspire 1200.
Drop down to line 6, then go across to the right, and click on 5515.

This is a PDF file. The computer you are on now has Adobe Reader on it, which uses PDF files.
I would suggest upgrading to Adobe Reader 9 (9.3.4.) though, if this isn't the version on the computer.

After you click you may not see anything happening for up to 30 seconds.
The file is downloading in the background.
Usually it takes a few seconds to see the first page, and additional time to fully download.
Suggest you let the file fully download before looking through it.

This is a SERVICE MANUAL, not a User Manual. Much more detailed, including disassembly procedures.
