    My laptop computer (Dell Inspiron 8500) made a funny sound and the monitor shut off, Upon pressing the power button again all it shows now are streaks or bands of changing color and then the screen fades to pure white. What is wrong...is this the hard disc going bad. There are no bad noises.

The solution may be one of several things. here are my ideas in increasing severity.

1) Bad connection. Fix: tear apart the screen and check the video connection. It looks just like that when you don't have a good connection with the sync signals from the motherboard

2) Bad screen. Check video feed to external monitor. Shut down laptop. Plug in an external monitor. Start it up and the external monitor should show a good picture if the problem is a connection or a bad screen. If it's a bad screen, you will need to replace it (easy to do at home for 1/3 the cost of some outside source). Go to ifixit or instructables or repair4laptop to get ideas and walkthroughs. So, good feed to external monitor and no bad connections=bad screen... maybe.

3) bad video card. Replace motherboard = $$$. this is more difficult to do at home. If the external monitor shows the same streaky picture, you're pretty much guaranteed that you will have to replace the motherboard.

try pushing on various parts of the computer to see about bad connections, usually two thirds to three quarters of the way up the back of the screen is the connection and somewhere under the keyboard is the video card. don't press too hard, but see if anything's different when you try it. Good luck.

I just had this problem on my Dell lcd monitor. Turns out it was just a loose cable connection to the back of the monitor itself.

Streak in LCD Screen


Strip down and remake the connection to the ribbon cable. It has to be inserted squarely and evenly and then locked down. Make sure any spacers or locators are in properly between the two screens. Any pressure will cause display anomalies.

Streak in LCD Screen


Judith,

I'm going to state in my own words, as to what I think you have stated, originally; (Please bear with me as this may be clumsy)

" I have a Dell Inspiron 1525 Notebook PC.
This laptop has problems with the Hinges, and Base Cover.

The Base Cover area where the Hinges, and their respective screws go, is beyond repair. To properly repair it, I would need to purchase a Base Cover, Hinges, Hinge Brackets, and a 'Bezel'."

At this stage I am a little unclear,
" I think I would have to buy the entire bottom of the case,
{ Base Cover. Got it }, and replace the bezel that had pieces break off at the hinges too,....."

Hmmm.....Bezel....
Bezel that is close to the Hinges,..........

1) The Display Bezel that is in Front of the LCD screen? Thin plastic frame that resembles a picture frame? Bottom part has Hinge Covers formed in it?

2) Palm Rest Cover?
The cover that covers the top of the Body, of the laptop?

The major portion is below the Keyboard towards you. The rest of the Palm Rest Cover, is two rectangular pieces on each side of the Keyboard.

One of these two pieces broke? (Connector piece?)

3) Center Control Cover?
Is above the Keyboard, and below the Display Assembly.
Has the Power on button in it, for one.

To go on;

You purchased the same model on Ebay?

Same exact model number? Look on the bottom of the laptop.

Reasoning?
Primer:

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

A Backlight (Present technology), can be a CCFL, or a series of LED lights.
The Dell Inspiron 1525 series used a CCFL.

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

(Approximately 2mm Thick, by almost the height of the LCD screen, Long.
2mm is a little larger than 1/16th of an Inch. { .0787 )

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

Point?
The screen Inverter, and the LCD screen, are a MATCHED unit.

Looking at the back of both LCD screens, what is the Dell part number/s, or LCD manufacturer model number/s?

[ One LG example from an article on InsideMyLaptop,

http://www.insidemylaptop.com/replace-lcd-screen-inverter-dell-inspiron-1525-laptop/

Scroll all the way down to Step 14. Read under the first photo, and view the second photo ]

Want to see if the LCD screen you are using, matches the Inverter in the laptop.

Dell, just like all laptop manufacturers, use different manufacturers of LCD screens. (LG, Sharp, Hitachi, etc)
May go with one for a few years, then off to a different one. (Or one's)
May change when a particular laptop model comes out.

The LCD screens may be slightly different models. In turn they would use different screen Inverters.
This = No.

4) Translucent 'streak' going from bottom left corner, to upper right corner.

That translates to;

A) Video Cable damage (Dell = Display Cable)
B) LCD screen damage
C) Bad graphics chipset

Have you used an external monitor to diagnose? A VGA monitor?
If so disregard the following;

A) Laptop OFF, monitor OFF. Connect a VGA monitor to the laptop.
You can use a CRT monitor (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable attached.

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

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

Connect to the left side of the laptop.

B) 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 VGA monitor.
If not:

Hold the Fn key down, simultaneously tap once on the F8 key.
Still nothing showing on external monitor?

You have at least three display options;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY.

Try again.

If the display is the same on the external VGA monitor, you have a bad graphics chipset. (G.P.U.)

If Not, the problem lies in the Display Cable, or screen Inverter, or LCD screen.

As you have seen the Display Cable connects to the motherboard, then routes up under the Left Hinge, and up into the Display Assembly.

The Display Cable can be damaged from normal use, over time.
Now add to it that you have had extensive Hinge problems.

If the sheath of the cable shows any visible damage, the tiny wires inside stand a chance of being damaged, also. (Stretched/Broken)

I would suggest testing the Display Cable. Perform a continuity test with a multimeter, for each wire in the Display Cable.

[ An economical multimeter can be purchased for around $8 to $12.
Available in a multitude of stores. An auto parts store is but one example.
Or perhaps you know someone who has a multimeter. Analog or digital is fine]

C) Did you reconnect the Wireless Antenna Cables correctly?
Reaching here but inquiring minds want to know.

[ The above is from - Dell Support > Inspiron 1525/1526 Service Manual,

http://support.dell.com/support/edocs/systems/ins1525/en/SM/index.htm

]

D) Would like to know what you did to follow Anti-Static Precautions?


I'm not following on the points of;

1) You installed what you considered to be a working LCD screen, into a laptop you bought off of Ebay; and the display stopped working on the Ebay laptop?

Or;

2) Or is your statement, that after receiving the Ebay laptop, your original laptop would no longer show graphics on it's display?

IMHO I would use the case parts of the Ebay laptop, and rebuild your original laptop.

Awaiting corrections, and possible questions.

Regards,

Samsung 940NW Streaking


Your description, without a photo of the streaking leaves us to wonder what direction the streaking occurs. If it is vertical, the LCD display has bad edge connections and the only service you can do is attempt to locate the bad connections by pressing the edge of the display till the streaks cease, then locate the portion on the board and solder it. Another type of streaking that cannot be repaired is the actual loss of LCD contrast in the display. The display has to be replaced. Horizontal lines are usually the result of a board issue and the whole board is replaced. The CCFL tubes get yellow tint to them when the get older and that is right after they get brighter.

Horizontal lines that look like streaks or smears going from left to right


Horizontal lines that look like streaks or smears, you need consider:
1) video card memory error cause it if the display memory on the video card
2) check RAM (clean pins and slot pin)
3) monitor power on without cable to see the menu display, it is ok if no streak, need to clean monitor cable plug.

Change of a virus on your n95 is really small. I think you have just a bad screen. If warranty is still valid, i think you should try to get a new one. Otherwise, you should get a new screen and a some information on how to replace the screen.
