Pink screen


Problem can be;

1) Graphics chipset
2) Video Cable
3) screen Inverter (IF Used)
4) LCD screen

Diagnose to find out.
I need the laptop manufacturer name, and model number.
Model number can be found on the Bottom of the laptop.

Post back in a Comment.

A) Graphics chipset:

An external monitor is used to check, and see if the display is also pinkish on it; or it is OK. Info posted I need, I will detail this procedure out step by step.

Display good on external monitor means graphics chipset is OK.
(Mounting is usually the problem)
Means problem is screen Inverter (IF used), or Video Cable, or LCD screen.

B) Video Cable:

The Video Cable connects to the motherboard, in an area under the Keyboard, or under the Switch Cover.
(Depending on laptop design, Switch Cover may be an integral part of Palm Rest Cover)

From there it leads under, or close by the left Hinge; and then goes up into the Display Assembly.

IF, a screen Inverter is used, the Video Cable has a separate small cable that branches off; and connects to one side of the screen Inverter.
The main part of the Video Cable connects to the back of the LCD screen.

Just due to normal repeated opening, and closing of the laptop; the Video Cable may become pulled on, and/or pinched.
This can lead to a loose connection at the motherboard side, or LCD screen side. (and/or screen Inverter, IF screen Inverter is used)

Can also lead to a damaged Video Cable. (Stretched/Broken wires inside it)
This can cause a pinkish screen.

C) screen Inverter:

With Backlighting that uses CCFL/s for a Backlight, a screen Inverter is used.
(Cold Cathode Fluorescent Lamp)

For Backlighting that is LED, a screen Inverter MAY, or MAY NOT be used.
(First design LED backlighting seemed to. Later design LED backlighting, does not. Light Emitting Diode)

A screen Inverter is used to convert the power (Electricity), from the laptop; for the LCD screen and Backlight.
Screen Inverter going out, can cause a pinkish screen.

D) LCD screen:
Graphics chipset is good, Video Cable connections are good; no damaged Video Cable, screen Inverter is good (IF used); problem is LCD screen.

Awaiting manufacturer name, and model number.

My ibook g3 gives me this when i boot it up(just got it from eBay) and the cd drive doesn't open up


Probably last owner had experiment with installing windows on iBook something that apple does not support until now. You can solve this by buying a genuine copy of macintosh (should not be more than 10-20 bucks on ebay for this is a kinda old version not sure which one though) and reinstall it basically from the begining.

I have a Sony vaio PCG 5K7P, and it's not getting started...when I switch it on...only the fan works and the lights on wifi and the charger are working....no display on the screen and no processor


Laptop on, shine a flashlight at the LCD screen at various angles.
If you see a faint image the problem is the Backlight, or screen Inverter.

90 PERCENT OF THE TIME the fault can be attributed to a bad screen Inverter.
(IF the laptop uses a screen Inverter.
CCFL backlighting uses a screen Inverter.
LED backlighting may, or may Not use a screen Inverter)

No faint images?

See if the problem is the graphics chipset, or Video Cable, or inside the Display Assembly.

Graphics chipset:
Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port, on the laptop.

This is an example of a VGA Cable, and VGA connector, (port),

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

Scroll down a little for cable example.
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 of monitor allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.
IF not;

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, and at the same time tap once on the F8 key. (The F8 key is the Display Toggle-Over key)
Still no display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F8 key.

No display on external monitor, suggests a problem with the graphics chipset.

Most of the time the graphics chipset itself isn't the problem.
It is due to inadequate cooling for the graphics chipset, and this causes a problem with the MOUNTING, of the graphics chipset TO motherboard. (BGA surface mount)

If this is found to be the problem I will go into more detail.
I don't believe that is your problem, but there is NO guessing here.
We are following a diagnostic flowchart.

Good graphics on the external VGA monitor, means there is a problem with the Video Cable, or inside the Display Assembly.

A) Video Cable connections can be loose.
Connection at motherboard side, or connection of small cable to screen Inverter from Video Cable, (IF it uses a screen Inverter), or connection at back of LCD screen.

A LOT of times a loose connection can cause what you are seeing.

Video Cable could be damaged. Wires inside stretched/broken.

Inside the Display Assembly:
Video Cable checks out after a continuity test, then the screen Inverter is next in the diagnosis. (IF a screen Inverter is used)

Screen Inverter proves to be good, the problem is the LCD screen.
NO screen Inverter is used, the problem is the LCD screen.

Sony drives me crazy with their model numbering system.
What is the other model number on the bottom of the laptop?
Start with a VGN?
Post back in a Comment.

Once I have a model number I can deal with, I will post back with step by step info, and additional manual information.
(Service Manual. Perhaps pictorial guides, and video/s)

White screen acer


White screen when you start the laptop, and then when you connect an external VGA monitor, you can only operate in Safe Mode?

Or white screen except when you are Safe Mode?

Doesn't matter anyway, just wanted to see what you are stating.

1) Have you connected an external VGA monitor to the laptop, and seen if you get a good display on the external VGA monitor?

No display on external 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

Hold the Fn key down, and 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.

Good display on external VGA monitor?
Problem is the Video Cable, or inside the Display Assembly.

White screen on external VGA monitor also?
Problem is the graphics chipset.

[Actually it is probably inadequate cooling for the graphics chipset, and this makes a bad contact of graphics chipset TO motherboard. If this is found to be the problem I can explain further, and in much more detail ]

Inside the Display Assembly:

A) Screen Inverter if it is CCFL backlighting.
May or may NOT be a screen Inverter if it uses LED backlighting.

[ CCFL - Cold Cathode Fluorescent Lamp
LED - Light Emitting Diode ]

B) LCD screen.

Video Cable:
The Video Cable connects to the motherboard, in an area either under the Keyboard, or under the Switch Cover, or bottom of the laptop.

[Switch Cover,
Goes by many names. It is the strip of plastic above the Keyboard, and below the LCD screen. Usually has the Power On button, and LED indicator lights; plus speakers, sometimes ]

From there the Video Cable goes under the left Hinge, and up into the Display Assembly.
If a screen Inverter is used, a small cable comes from the main cable, and plugs into the screen Inverter.
The main cable connects to the back of the LCD screen.

Due to normal repeated opening, and closing of the laptop; the Video Cable may be pulled on.
This can create a bad connection on motherboard side, and/or screen Inverter cable connection, (IF used), or to the back of the LCD screen.

It can also cause damage to the Video Cable.
(Stretched/Broken wires)

Once you post the product number I can guide you step by step, show you the components I'm talking about, and track down a Service Manual link, and possibly pictorial disassembly information.

The Video Cable connections are checked first.
A loose connection can cause what you are seeing.

The sheath of the Video Cable is also scrutinized for damage.
Obvious damage to the sheath, may mean damage to the tiny wires inside the Video Cable.

Another thing that can cause what you are seeing.

Video Cable connections prove not to be the problem, then the Video Cable is to be removed, and a continuity test performed on it.
Multimeter set to OHM's. (1K)

If a multimeter is not at your access, then suggest taking the Video 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 Video Cable as the problem, before going on.

Video Cable checks out?
Then if a screen Inverter is used, this is the next component in the diagnostic flowchart.

Problem is this; it requires a sensitive multimeter to test a screen Inverter. Think fairly expensive,

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

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

Due to the multimeter issue, the above noted ease of accessing to replace, and the usually low cost of the screen Inverter; most decide to just replace.

Screen Inverter replaced? Same problem?
The problem is the LCD screen.

No screen Inverter used? The problem is the LCD screen.

Video Cable; Usually around $9 to $20
Screen Inverter; Same.
LCD Screen; from $70 to $240. Just depends on what Lenovo laptop we're talking about here.

This is why you diagnose first.
Would be foolish to assume the problem is the LCD screen, and purchase one; when the problem may have just been a loose Video Cable connection, or one of the $9 to $20 components stated above.

Ready to diagnose?
Post the Product Number back in a Comment.

Hi lewis haywar,

Try to replace the LCD inverter in your laptop. Most common issues on LCD are due to failing LCD inverter. It fails more often than LCD cable or LCD backlight does.

Please let me know if this solution helped to resolve your issue.

Asus laptop and red shadows on letters and bad picture. is this a lcd inverter problem? External monitor works ok.I check lcd panel cable and replace lcd panel but all same


Yep, it's the inverter. Anytime there is a red or pinkish tint or hue you know it is the inverter. Usually the inverter is very easy to change. I would buy one on eBay for your best price...
Good luck!! EJ Kudelka

Lcd blanks out


It's either the "inverter" or some loose connections.
Either way, take the computer to a qualified technician to trouble-shoot, and/or to replace the LCD screen.

Acer Aspire 6530G black screen


Hi,
There's no point getting a crisis program if you cannot see the screen in the first place.
The problem could be anything from a faulty graphics, faulty motherboard or loose cable or inverter board.
To test this connect an external monitor to the laptop and use the keyboard toggle to switch screens (hold down Fn and press the F key that has a monitor icon on it)
If the external monitor has a display on it then the problem is the inverter, inverter cable or the screen itself which if faulty.
If there is no display on the external monitor you maybe looking at a new laptop.
If you have no external monitor to test then look very close at the laptop screen, if you can just make out an image then its the inverter.
Post back if you require any more assistance.



Regards.

LCD Problem


hook up the ibook to a external monitor, via the monitor cable, if it comes up, you know its not your motherboard. There should be a monitor icon on your keyboard to switch from laptop monitor to external monitor, it could have been pressed by accident.
