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.

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,

My HP monitor was working fine then randomly one day it went dead, I turned it back on and I could see the screen and what it displayed for about 2 seconds, then the screen dies again. The power button is...


Sounds like your monitor is going dead. If its under warranty that would be the best way to go. Specifically it sounds like the power inverter is dead or there is a busted capacitor.

N95 Virus?


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.

Razr v3c the screen is dim all the time


it would be your display light is out and as far as I know the only way to fix that is to get a whole new LCD screen assembly. If that is the case go buy a new phone and not a RZR I know it's popular but honestly I've seen hundred's of them in my store busted and unusable after only a month or so. Not all motorola phones are bad but this one is the biggest piece of crap. I rank it with Kyocera phones!!!!!!
