Question about NEC Computers & Internet

6 Answers

I have 4 NEC LCDs. In moving one of the NEC LCD 1990SXi displays recently, something happened so that the frames around Windows aplications are now distorted. The frames are supposed to be blue but a slight magenta is coming through on the edge of the frame closest to the application being viewed. Also, when picking colors, cyan is now gray and no cyan is seen on application color palettes. The minimize button has a sharper contrasting highlight within. I looked at OSM Tag 6 and settings appear normal. Please advise.

If Cyan is gray, and blue is magenta, that means that you lost the Cyan channel on the color scales and color tracking.

If you are lucky this is caused by a misplaced ribbon cable. Otherwise this is caused bya faulty digital board aor a defective LCD display.

You can test the display using a software like : |MG| DisplayMate 1.30

If this happend just after moving it and it is an lcd the problems you are discribing sound like a bad connection on the back of the lcd itself, unlike crts if you see a distortion like that it may also be board inside the monitor that converts the signal to picture and please people on here either read the full post and reply with stuff that is relevent (this is monitor issue not computer issue and it is not a crt problem cause it is not a crt)

Hi So now we need to know if power is getting to the cd and hard drive. Without a power supply tester it will be hard so I"d take the power supply out and ask my local pc repair shop to test it for me. If it's good then I'd be thinking motherboard. Since neither the cd or hard drive are detected it wouldn't make since that both ide cables had gone bad. I"ve found some info at http://support.dell.com/support/edocs/systems/dim4700/sm/adtshoot.htm#wp1054081 
which has trouble shooting light codes. I"d be interested in what the error code on the lights is. It also has diagrams for those of us that don't know about the inside of pc's. 
The way I troubleshoot the motherboard is to take everything off the board, then one at a time reseat the RAM then try to power on the mb and listen of beeps. Then hook up the ide to the cd and listen for beeps. then the hard drive and listen for beeps and look for messages on the screen. Let me know what the status is.
Thanks,

    Make sure the hard drive is connected to the ide cable that has a blue end. Don't connect anything else to this cable. when the pc is booting up watch the screen for the option to enter setup usually Del, or F2. Once into the bios see if the boot options are set to cd first and ide 0 second. You can also see if the hard drive is being detected in the bios.
    Hope this helps. Let me know.
    Thanks,

Hi and welcome to FixYa,

Initially, would venture a possible loose or partially disconnected cable internal to the unit. Of course it is also possible that a pin in the video cable is bent or out of place or worst broken. best course of action is to perform visual inspection of these possibilities.

Good luck and Thank you for using FixYa. Happy Holidays.

Check that all the connections from the PC to the monitors are tight and snug, go into the display properties and check that all of them are displaying the correct colours (for example 32bit on each) if you have still no joy after this then i would suggest you remove all but one of the monitors, reintall the graphics drivers and set all of the monitors again

kind regards

I have a gateway netbook and the screen turns white after startup. What can I do to fix it?


Sure wish I knew the exact Model Number of this netbook. It's on the bottom in a white Service Tag, or sticker.

All I can give you is generic information.

On the back of the netbook, or on one of the sides, is a VGA connector. (Perhaps even the front)

This is a basic example of a VGA cable, and a VGA connector, (To the right is the connector),

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


Netbook OFF, monitor OFF, connect the VGA cable of the monitor to the VGA connector on the netbook.

You can use a CRT monitor that looks like a small TV, or an LCD flat screen monitor that has a VGA cable.

Turn the monitor on. IF it is a CRT monitor give it a few minutes to 'warm up'.
Turn the netbook on.

IF the display does not automatically come up on the external monitor, (The VGA monitor), press, and hold down on the Fn key, and at the same time tap once on the Display toggle-over key.

Again generic information;
The Fn key is usually located on the Keyboard near the CTRL key to the left.
I have no idea where your Display toggle-over key is.

This key will be one of the Function keys at the top of the keyboard. Either F1, F2, F3, F4, F5, F6, F7, and so on.

There should be a monitor symbol on this particular key. Will look like an empty rectangle with rounded corners. Supposed to represent a monitor. There may be an arrow to one side of it.

The arrow represents the display moving over.

Different laptops, (netbooks), have different options.
Usual is;
1) Just the internal monitor of the laptop
2) Internal monitor of the laptop, AND the external monitor
3) External monitor Only.

Do to there being more than one option, you may have to tap the Display toggle-over key more than once.

A) White screen also shows on external VGA monitor?
You have a bad graphics chipset.

For most laptops, and I'm betting with this netbook, the graphics chipset is soldered directly to the motherboard. This is Integrated Graphics.

Another term for Integrated Graphics is OnBoard Graphics.
ON the motherBOARD.

This would mean replacing the motherboard.

(IF the netbook does indeed have a graphics card, the card could be replaced, and not the motherboard)


B) Display on external VGA monitor is okay?
There is a problem with the Display Assembly.

Essentially, the entire upper half of the netbook, is the Display Assembly.

1) Display Cover: The plastic top cover of the netbook.
2) LCD screen
3) Display Bezel: The thin plastic frame in front of the LCD screen. Resembles a picture frame
4) Inverter (Screen Inverter)
5) Webcam (IF installed)
6) Brackets which hold the LCD screen to the Display Cover, LCD screen frame, Hinges, various screws, and so on.

Primer:
1) An LCD screen does not produce light. It needs an additional light source.
A Backlight is the additional light source.

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

This example is just to show you where one type of Backlight is located, and what an average Backlight looks like,

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

With a LOT of laptops, and probably this netbook, the general repair method for replacing a Backlight is to replace the LCD screen.

An LCD screen is composed of layers. These layers are held in place by the Display Frame. A thin metal frame which surrounds the outside edges of the LCD screen layers. Also resembles a picture frame.

As you can see from the above link, the Backlight is accessed by removing the Display Frame on one side, or all together. This allows the LCD screen layers to move around. They MUST be kept, or put back in the exact location they were in, as set by the factory.

This is why the general repair method is to replace the LCD screen, for those who do not possess the technical skill of replacing, OR the manufacturer does not offer just the Backlight bulb.
{LCD screen = $$$$$. Backlight bulb is usually around $15 to $30}

2) Inverter:
An Inverter converts the electricity from the laptop for the Backlight.
In 90 PERCENT of Display Assembly problems, the fault is the Inverter.

OR, it may just be a loose Video Cable, or Inverter Cable.
The connections may be loose.

This requires partially disassembling the netbook, down to the connection of the Video Cable TO the motherboard, to see if this connection is tight, and may also require disassembling the Display Assembly partway, to see if the connection of the Video Cable TO the LCD screen is tight.

{You cannot just eyeball the connections. They need to be physically checked to see if they are plugged in tightly}

Requires partial disassembly of the Display Assembly, to see if the connection TO the Inverter is tight, and FROM the Inverter to the Backlight is tight.

Connections prove to be tight, visually inspect the sheath of the Video Cable for obvious signs of damage. If the sheath is damaged, there is a good chance that one of the thin tiny wires inside it has become stretched, and is broken.

Obvious signs of damage, or not, I would suggest removing the Video Cable, and with a multimeter set to Ohms,(1K) check the continuity of the individual wires in the Video Cable.

Be sure the problem is not the Video Cable.

Video Cable proves to be good, replace the Inverter.

(Replacing an Inverter is a simple task, and the cost of the Inverter is economical enough to warrant this type of procedure, IMHO)

Still no satisfaction? Replace the LCD screen.

Post the Model Number in a Comment, and I'll make this solution more custom to THE netbook you have.

My screen on my laptop just went all black with a very faint image. what is wrong there, how do i fix it, and what made this happen?


A) What is wrong?;
Your Backlight has gone bad, or the Inverter.

B) How do I fix it?
Replace the Backlight bulb, or the Inverter

C) Backlight bulb's, and Inverters, like everything have a 'lifespan'
This one is at the end of it's. (Stating the Backlight or the Inverter

From here all I can give you is Generic information, since I do not have the laptop manufacturer name, and Model Number. This is on the bottom of the laptop.

1) An LCD screen cannot produce enough light by itself. A Backlight bulb, (Or more than one), is used to emit enough light.

2) A laptop cannot produce enough power to power the LCD screen, and is also used for power to the Backlight.

I'll have to discuss the way the Display Assembly is put together, and name parts in order to explain the following of how to repair. Again, generic information.

1a) The plastic top of the laptop is the Top Cover. There are different names used by different manufacturers.

1b) Looking at the LCD screen with the laptop open, there is a plastic frame that goes around the edges of the LCD screen, and is in Front.
This is the Display Bezel

1c) The LCD screen is behind the Display Bezel. The LCD screen is a composite of layers. The outside layer that faces you is a protective screen.
Around these layers composing the LCD screen, is a metal frame.
One side, (Or both sides) of the metal frame is removed to access the Backlight bulb.

1d) The Backlight bulb is a CCFL.
Cold Cathode Fluorescent Lamp.
Very similar to the fluorescent lamps, (Bulbs) uses in residential, and commercial applications, but on a MUCH smaller scale.

Now to show you generic laptop info on replacing the Backlight bulb for them.

A) http://www.insidemylaptop.com/category/backlight/

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

If I had the laptop manufacturer name, and Model Number, I could try to give you a link to the Service Manual for the laptop. (Free. Usually from the laptop manufacturer)
This way you would have Exact info on how to disassemble your laptop's Display Assembly.

Hi there, I have a toshiba satellite M60-BK3 Laptop. Is only four years old and from couple of days my LCD display is going on standby mode very fast. I try pressing and releasing that little switch which...


A couple things to try, 1 is boot the system in the safe mode (F8 menu at boot) and see if the LCD turns off there. You can also attach an external monitor and see if the external looses video too.
If the system looses video in the Safe mode and doesn't loose video with an external monitor, then the LCD backlight is likely failing
LCDs run about $100 to $150 on ebay

I have an error message on my screen which ios moving around. It says - 'not optimum mode. Recommended mode : 1280 x1024 60Hz'.


Sounds like you have an LCD monitor. LCD monitors look best in their native resolution. Yours must be 1280x1024. You need to (assuming this is a Windows PC) right click on the desktop and choose Personalize, Display Settings (Vista) or Properties, Settings (XP or older). Set the slider to 1280x1024. It'll confirm the change and then the message should never reappear.

Widescreen 22" monitor won't stretch to fit screen


Without more details, it is really hard to provide assistance but here are some general items without knowing the model Monitor, the video card or the operating system you are using.

Generally (I can't know for sure without the LCD model) 22 inch LCDs have an optimal resolution of 1680 by 1050 pixels.

So the first thing you need to do is ensure that the video card display resolution is set to 1680 by 1050. If 1680 by 1050 is not an option in your display properties (In windows XP, right click the background, click properties, click settings tab, then slide the resolution bar to 1680 by 1050. Click OK) then try upgrading your video driver.

If that doesn't give you the 1680 by 1050 option, then your video card may need replacement with a better card.

Display has red tinge


Unfortunately that means the back light on your LCD is bad. The backlights in LCDs aren't meant to be replaced, however, it is possible. It is a fairly difficult process outlined here good luck!
