Acer Aspire 9300 external monitor problem

While I'm waiting for a new inverter (laptop screen no longer lights up), I'm using an LG lcd display as an external monitor. When I try to watch a dvd movie, or click on something that will open up Windows Media Player, the whole screen is taken up by the movie and I lose the ability to do anything, and am stuck with that display screen, even when the file or dvd is done playing.

Pressing the Windows key doesn't help. Pressing the Esc key doesn't help. I end up having to press the power button to shut off the computer, then restart it.

Do you have any ideas?

When that happens again try pressing alt+esc. If that doesn't help try changing the resolution or the refresh rate of the monitor.

I've tried to connect my laptop to a projector but i just get the information projected but cant be seen on my screen of the laptop


You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key a few times. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 ASUS and Dell = Fn + F8

Trying to fix laptop screen that is whited out


Alex,
A primer first;

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

A Backlight can be a CCFL, (Or two of them), or a series of LED's.
(Light Emitting Diode)

The Acer Aspire 5732z-4855 Notebook PC uses a single CCFL, according to all of the websites that sell the LCD screen. One example,

https://www.laptopscreen.com/English/model/Acer/ASPIRE~5732Z-4855/

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

[Average thickness is 2mm. That is a little larger than 1/16th of an Inch, or about the width of this letter -> H
Average length is almost as long, as the LCD screen is in height.
A general example of a CCFL,

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

View the last 8 photos ]

A screen Inverter is used to convert the power from the laptop, for the LCD screen, and Backlight.
(For a CCFL. Most generally LED backlighting does not use a screen Inverter )

Example of a screen Inverter used on the Acer Aspire 5732z series of Notebook PC's,

http://www.lcd-inverter.co.uk/screen-inverter.php/acer_aspire+5732z_lcd-inverter_6130.htm

Primer over.

Your problem could be the graphics chipset, Video Cable, screen Inverter, or LCD screen.

Diagnose:

1) Graphics Chipset;
Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.

[ Left rear side has the VGA port. It is White in color. This is a general example of a VGA Cable, and VGA connector, (Port),

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

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

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

If not;
Hold the Fn key down, (Bottom row, second key from left), and at the same time tap once on the F5 key.
(The F5 key is the Display Toggle-Over key)

Still no display on the external VGA monitor?
There are at least 3 display options available;

1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Hold the Fn key down again, and tap once more on the F5 key.
Good graphics (Display) on the external VGA monitor, means you have a good graphics chipset.

Bad graphics on the external VGA monitor, means you are looking at motherboard replacement.

Sitting here in this chair in front of my computer, I'm willing to bet your graphics chipset is OK.

If the graphics chipset is good your problem is the Video Cable, screen Inverter, or LCD screen.

2) Video Cable:
This is high on the list for being the 'culprit' of the problem.
Why?
Because of it's location.

The Video Cable connects to the top of the motherboard, in an area under the Switch Cover, and slightly to the right of the left Hinge.

It then routes UNDER the left Hinge, and up into the Display Assembly. From there it connects to the back of the LCD screen, and to the screen Inverter.

Just from normal opening, and closing of the laptop over time, the Video Cable may become pinched.
This can lead to pulling on the Video Cable, and may cause a loose connection at the motherboard side, or LCD screen side. Shouldn't be a loose connection at the screen Inverter.

This means the Switch Cover must be removed to check the connection, at the motherboard side. The Display Assembly is opened up, and connection at the back of the LCD screen is checked.

Visual inspection will do NO good. You CANNOT see usually if the connections are tight, or not. It is BEST to physically see if you can plug the cable connections in tighter.

Loose connections of the Video Cable are high on the list, for your kind of problem.

Next is damage to the Video Cable. See if there are any obvious signs of damage to the sheath of the Video Cable. Obvious damage to the sheath may mean damage to the tiny wires inside.
(Stretched/Broken)

Even if there are no signs of damage to the Video Cable, and if physically checking to see if the Video Cable's connections are loose, and this doesn't solve the problem; the Video Cable should be removed, and it's wires checked for continuity with a multimeter.

(You can take it to a 'Mom and Pop' computer store, and have it checked for a few bucks )

Video Cable checks out, the next hardware part in the diagnoses is the screen Inverter.
[Acer nomenclature for the Video Cable is LCD Panel Cable]

3) Screen Inverter:
The thin plastic frame in front of the LCD screen is the Display Bezel.

[Acer nomenclature for the Display Bezel is LCD Bezel.
The LCD screen is an LCD Panel.
Display Assembly is an LCD Module ]

The screen Inverter is located behind the LCD Bezel, and mounted towards the bottom of the LCD screen.
Testing requires a sensitive multimeter. Read fairly expensive,

http://www.fonerbooks.com/test.htm

If you do not have access to a sensitive multimeter, then the next course would be to replace the screen Inverter.
Due to the low price of a new one, this parts changing solution IMHO is feasible.

Screen Inverter is not the problem, then the problem is the LCD screen.

I believe your problem to be the Video Cable. Loose or damaged. If not then the screen Inverter.

Screen


Problem can be the problems with the graphics chipset, (Mounting issues due to overheating), video cable, screen Inverter, or LCD screen itself.

http://www.ebay.com/itm/Acer-Aspire-5241-5516-5517-5541-5541G-486736-001-Series-LCD-screen-Inverter-/261077449831?pt=LH_DefaultDomain_0&hash=item3cc96dbc67

Not advertising for the above website, nor seller. The above is used for reference, to show what the screen Inverter looks like

It's about 4 inches Long, (101.6mm), and 3/8ths of an Inch Wide.
(.375 inches, or approximately 9.52mm)

Primer:

An LCD screen cannot produce light by itself,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

Click on - No Thanks, and the monitor icon.
(You may wish to turn your sound down first)

A Backlight is used to provide the light.
A Backlight can be a CCFL, or a series of LED's.
(Light Emitting Diode)

Looking at the LCD screens offered for the Acer Aspire 5517 series of Notebook PC's, there are two backlight types offered.
CCFL and LED.

(Aspire 5517 just designates a model series. The actual model number follows it. 5997, 5571, and 5535, are just some of the examples of a model number. It's on the bottom of the laptop)

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

Average thickness is 2mm. That is a little larger than 1/16th of an Inch. About this thick -> aa
Average length is almost as long, as the LCD screen is in height.

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

90 PERCENT OF THE TIME the fault is a bad screen Inverter.

HOWEVER, when LED backlighting first came out, they were using a screen Inverter. Technology changed, and a screen Inverter is no longer used for a backlight using LED's.

Fun stuff, huh? It really isn't an issue. If your laptop is using LED's for a Backlight, it will be proudly stated on the laptop. Usually on a sticker to the right, or left of the Touchpad.

Primer over.

Now we get technical;

Diagnose:

A) Laptop OFF, monitor OFF, attach a VGA monitor to the VGA connector on the laptop. Right rear side, blue in color.
General example of a VGA Cable, and VGA connector,

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

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

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

IF not;

There are at least 3 display options;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY.

Hold the Fn key down, (Bottom of Keyboard, second key from left), and at the same time tap once on the F5 key.
(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.
Still no display? You have a graphics chipset problem. More on this at the end of the solution.

Display on external VGA monitor? You have a problem with the Video Cable, screen Inverter, or LCD screen.

C) Video Cable: (For Acer it is LCD Cable. I will still refer to it as the video cable)

The video cable attaches to the motherboard under the Switch Cover.
(Switch Cover is the plastic strip under the LCD screen, and above the Keyboard.
LED indicator lights, and Power On switch are covered by it)

The video cable then goes under the left Hinge, and up into the LCD Module. (Acer name for Display Assembly)
From there it connects to the back of the LCD screen.
(Acer = LCD Panel)

Due to normal repeated opening, and closing of the laptop, the video cable may become pinched, and pulled on.
This can create a loose connection at the motherboard side, or LCD screen side.

IF the laptop uses a screen Inverter, the video cable also connects to it. Can be pulled loose from the screen Inverter too.
Here is an example of a video cable for an Acer Aspire 5517,

http://www.batterystyle.com/acer-aspire-5517-cable-p-514000.html

Click on the photo view to enlarge.
The bottom side is the side that connects to the motherboard. The connector is hidden from view by the rectangular plastic strip.

This strip is used to gently pull on, and disconnect the motherboard side of the video cable, from the motherboard.
The top side connects to the back of the LCD screen.

Where the top part of the cable meets the wider lower part, you can see a small looped cable. This cable plugs into the screen Inverter.

(Either this video cable can be used for a laptop with CCFL backlighting, or it may be that the screen Inverter part of the cable is not used, if the laptop has LED backlighting. This is why the model number is always used to get the correct part, not just the model series number.

LED backlighting is relatively new, and I haven't had a laptop come to my shop that needs repair for this. I also am not going to take my new Acer Aspire 5552-3691 apart to see, lol! If it ain't broke leave it alone)

The laptop needs to be partially disassembled, in order to access the motherboard side of the video cable. Battery, and Switch Cover.
The LCD Module needs to be removed, and split open to access the LCD Panel side of the video cable.

Visual summation will NOT do. You need to physically try to plug the cable in tighter. All it takes is the space of this -> a, for there to be a loose connection.
You can leave the LCD module laying down on the table, with the video cable attached, to see if that was the problem before reassembling.

IF you see any apparent damage to the sheath of the video cable, also suspect damage to the tiny wires inside. (Stretched/Broken)
Suggest take it to the nearest 'Mom and Pop' computer store, and ask them to perform a continuity check on the cable.
(Multimeter set to OHM, 1K, and check all wires)
Damaged = Replace.

D) Screen Inverter:
To test a screen Inverter you need a sensitive multimeter. Read fairly expensive,

http://www.fonerbooks.com/test.htm

If no sensitive multimeter is available usual course is to simply replace it, due to the low cost, and ease of access to replace.
Parts changing I know, but sometimes it's the only feasible alternative.

Replacing does not repair the problem, or the laptop does not use a screen Inverter? Then the next step is to replace the LCD screen.

Here is a link to a free Service Manual,

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

Go to the subheading that begins with Aspire 1200. (1200 in blue)
Drop down to the subheading on the left in blue - 5330, and scroll across to 5517. Left-click on 5517.

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (5517) it may take up to 30 seconds, before the first page comes up.

White horizontal lines running across laptop screen


I did not see any white lines, Simon, in the screenshot.
Just sayin'.
(Glad you tried to post it though!)

The problem is caused by a faulty Video Cable, or it's in the Display Assembly.

However, you better start the diagnoses with using an external VGA monitor, and see if the lines show up on the external monitor, also.
This would indicate a bad graphics chipset.

For most people that would mean replacing the motherboard.

A) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA connector, on the Left side of the laptop.

Example of a VGA cable, and VGA port, (Connector),

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

You can use a external VGA monitor that is a CRT type, (Looks like a small TV), or a flat LCD screen monitor with a VGA cable.

A1) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By default the display should show on the external monitor.
IF Not,

Press, and hold down on the Fn key, (Bottom left of Keyboard), and at the same time tap on the F5 key. (Top of Keyboard)
{The F5 key is the Display Toggle-Over key }

No?
There are at least 3 display options available.
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY.

Hold the Fn key down again, and tap once more on the F5 key.

Graphics look good on external VGA monitor?
Your graphics chipset is good.
Problem is Video Cable, or in the Display Assembly.

B) Video Cable: (LVDS Cable)

http://www.insidemylaptop.com/disassemble-acer-aspire-7551g-laptop/

The above is for an Acer Aspire 7751G, but it is close enough to the 7750G models, and info should directly crossover.

Scroll down to Step 17.
The Video Cable connection to the motherboard, is shown by the yellow arrow at the Top Left.

Note, although the photo is less than, the routing of the Video Cable.
It goes through the Left Hinge.
(Then into the Display Assembly, and connects to the back of the LCD screen)

With normal opening, and closing of the laptop, the Video Cable could be pinched, or have been pinched. Could have been pulled on.

You close the laptop, the cable is slightly pinched in the Hinge, and it pulls loose from the motherboard connection, AND/OR the LCD screen connection.

Doesn't take much of a loose connection. In fact it's hard to discern with the human eye, sometimes.
Make sure this motherboard connection is tight.

You have to open the Display Assembly, and check the Video Cable connection on the back of the LCD screen.

Doesn't look loose? Try to plug it in tighter anyway.

Check the connection of the wire/s from the Video Cable, TO the screen Inverter.
The small circuit board behind the Display Bezel, (LCD Bezel), and mounted to the bottom of the LCD screen.

When on the motherboard side, the side of the Video Cable that runs through the left Hinge, is there any apparent damage? Damage to the sheath of the Video Cable?

If there is, chances are the tiny wires inside the Video Cable, are damaged also.
Check with a multimeter. Perform a continuity test of Each wire.

C) Display Assembly:
Video Cable checks out then the problem is in the Display Assembly.

1) Screen Inverter:

http://www.sparepartswarehouse.com/Acer,Aspire-7700-thru-9800,Laptop,Inverters.aspx

http://www.insidemylaptop.com/replace-broken-screen-acer-aspire-5745g-laptop/

Not your model, granted. Posted for the Display Assembly dis-assembly pictorial guide.

Primer:
An LCD screen cannot produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight is a CCFL, or a series of LED lights.
Your laptop uses a series of LED lights for the Backlight.

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

A CCFL requires a screen Inverter.
A screen Inverter converts the power from the laptop, for the Backlight, and LCD screen.

NOT all LCD screens that use LED lights as a Backlight, use a screen Inverter. I suspect yours does not, as I can't find a listing for a screen Inverter, for it.

http://www.laptopscreen.com/English/section/FAQ/1245191276/Correct%20backlight%20type%20for%20your%20new%20screen/

This would mean that if the Video Cable proves to be good, the next step is to replace the LCD screen.

Shop around for the best price, AND make sure it is a direct replacement for yours.

The screen on my Acer ASPIRE 9300 has turned orange -


You could have a defective screen - a defective inverter or a CCFL lamp or simply the video cable needs reseating. After reseating the video cable and the problem is still there then :- To determine if you have a LCD screen or video card problem, read this and follow the instructions. Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills. Check out www.lcdparts.net for parts, repair service and DIY info.

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
