I dropped my laptop, now when i switch it on, the screen is striped to the point where nothing is legible. What can i do to fix this? Is it worth it?


Posted ahead of myself. There is a flow, or method; that is used, and should be followed,

1) Laptop OFF, monitor OFF; connect a VGA monitor to the VGA port, on the Left/middle side of the laptop. {White}
(General example of a VGA Cable, and VGA connector, {Port},

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

Scroll down a little for VGA Cable example)

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

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
No display on external VGA monitor?

There are at least 3 display options available;
A) Internal display of laptop ONLY
B) Internal display of laptop AND external VGA monitor
C) External VGA monitor ONLY

Press, and hold down on the Fn key, and at the same time tap once on the F7 key. (The F7 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 F7 key.

I think the display on the external VGA monitor, will be fine. Could I be wrong? Yes. If the display still has lines going through it; the graphics chipset's mounting to the motherboard, is the problem.

Most want to just replace the motherboard.
Now you're talking about bucks. $200 + for just the motherboard.

There are methods to reflow the graphics chipset's mounting, and re-seat the graphics chipset to motherboard. One professional, and a Bunch of amateur methods.
If you find this to be the problem, post back in a Comment, and we'll deal with it.

Good display on external VGA monitor, means the graphics chipset mounting is not the problem; the problem is the Video Cable, or inside the Display Assembly. (Screen Inverter/LCD screen)

The Video Cable plugs into the motherboard, under the Keyboard; in an area close to the Alt key on the left side of the Space Bar.
It then leads straight up towards the LCD screen, curves towards the left Hinge, and through the left Hinge.

From there the Video Cable leads up into the Display Assembly. Connects to the back of the LCD screen, and a small cable comes off the Video Cable to the Screen Inverter.

Laptop off, ALL power removed. (Remove the AC adapter {Charger}, and Battery)
Suggest lay a soft static free cloth on the table you're working on; and laptop turned Bottom side up, Battery Compartment facing away from you; down on the table.

You need to remove the Switch Cover, (Keyboard securing strip); above the Keyboard, and Keyboard laid over; in order to access the motherboard connector for the Video Cable.

http://www.insidemylaptop.com/take-apart-sony-vaio-vgn-fz220-repair-power-jack/

Go to Step 3. Remove the DVD drive.
Go to Step 4.
ONLY remove the screws circled in Green. They are for the Switch Cover.

Follow Steps 5 through 7. Remove the Switch Cover.
(Release those 3 Latches in Step 5, and 2 in Step 6)

Note* You want to use Finesse when removing the cover. This is not detailed here.
A stiff guitar pick, or a Spudger tool, are infinitely better than using a metal tool.

In Step 7 the tool should be gently inserted, on the Right side of the Switch Cover, at the parting line in-between the Switch Cover, and Bottom Cover. (Base Enclosure)

Once this side starts to lift up a little, use a small tool to gently pick up on the right Hinge cover. The Hinge cover is part of the Switch Cover.
Keep working along the bottom edge, and top edge of the Switch Cover, with your fingers, and pop it off.

(See the speakers in Step 8? NOT a good idea to use a metal tool, but also do Not insert the tool you are using; too far in )

Remove the two Philips head screws securing the Keyboard, at top.
Raise the Keyboard up on the screw side about 1 inch; slide the Keyboard towards the LCD screen a little.
You are trying to slide the plastic tabs at bottom of Keyboard, out of the Palm Rest Cover. (Top Cover)

Then lift the Keyboard up the screw side, roll over (Top), and lay Keyboard down on the Palm Rest Cover.
You do not need to remove it. Just access the Video Cable plug/motherboard connector.

Try to physically plug the motherboard side of the Video Cable, in tighter.
Photo in Step 10 shows gray Video Cable, and it's Black plug connector.

A) How to remove the Display Bezel, and lay LCD screen over a little, to check LCD screen side connection for Video Cable,

That is what he is disconnecting at 3:49

C) 12:20 to 16:10;

Example of the screen Inverter (Board),

http://www.ebay.com/itm/Sony-Vaio-VGN-FZ340E-15-4-Laptop-Genuine-1-443-890-11-LCD-Inverter-Board-Tested-/170770015618?pt=LH_DefaultDomain_0&hash=item27c2afa582

Check screen Inverter connection.

2) Showing how to partially remove LCD screen, and check Video Cable connection to LCD screen

I do Not think you need to remove the Display Assembly; in order to remove the Display Bezel.
That is why I posted the Insidemylaptop VAIO VGN-SZ 645 info, above.

You can check the laptop, after you may made sure all Video Cable connections are tight; and not put everything back together, before you do.
This way if the Video Cable connections are Not the problem, you do not have to disassemble all over again.

Visually inspect the sheath of the Video Cable.
If there is any apparent damage to the sheath of the cable, there is also a good chance the tiny wires inside the Video Cable, are damaged.
(Stretched/Broken)

You NEED to verify the Video Cable is Not the problem, before continuing on.
Connections weren't it; no apparent visual damage; remove the Video Cable, and take it to a small computer repair shop.
There the tech can take the cable, and with a multimeter set to OHM's, check each wire in the cable for Continuity.

(Also should have an assistant gently wiggle the cable, and see if there are any intermittent readings on the multimeter. Intermittent reading indicates broken wire/s )

Video Cable checks out; connections, and continuity test; the screen Inverter is next.
Test requires a Sensitive multimeter. Read fairly expensive,

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

Since ease of access, and low cost is a factor for the screen Inverter, most just decide to replace it.
(Parts changing I know; but if you do not have access to a sensitive multimeter? Take laptop to a shop to test screen Inverter, and you'll wind up paying for a screen Inverter, AND labor)

Screen Inverter checks out, or is replaced, and still same problem?
Replace LCD screen.

For additional questions, or clarification on anything I have stated above; please post in a Comment.

Laptop all whit screen


Dell Inspiron 1420 Notebook PC?

The white screen can be fixed. How?

Connect a VGA monitor to the laptop. Connect to the VGA port on the right rear. Example of a VGA Cable, and VGA connector,

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

You can use a CRT type monitor, (Looks like a small TV), or a flat LCD screen monitor that has a VGA cable.
By default the display should show on the external VGA monitor.

No?
Press, and hold the Fn key down, and at the same time tap the F8 key ONCE.
Still 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 F8 key.

No display on the external VGA monitor, means you have a bad graphics chipset. Replace motherboard.
Display does show on the external VGA monitor, means you have a problem with;

1) Video Cable
or
2) Screen Inverter
or
3) LCD screen

Video Cable:
The Display Panel Cable (Video Cable for Dell), connects to the motherboard by the left Hinge.
Goes under the left Hinge, and up into the Display Assembly.
It then connects to the Screen Inverter, and to the back of the Display Panel. (LCD screen for Dell)

From normal opening, and closing of the laptop, the Display Panel Cable may become pinched in the left Hinge.
This can cause;
A) The connection at the motherboard to come loose
B) The connection at the back of the Display Panel to come loose
C) Stretch the wires inside the Display Panel Cable's sheath, and damage the wires. (Break)

If you are lucky just the connection at the motherboard, and/or connection at the back of the Display panel, may have come loose.

Diagnoses is to NOT just look at the connections, but physically push the connectors of the Display Panel Cable, into the connector at the motherboard, AND back of the Display Panel.

Visually inspect the Display Panel Cable's sheath. Do you see any outward appearance of damage? This means the tiny wires inside may be damaged.
Replace the Display Panel Cable.

Remove ALL power. Remove the AC adapter (Charger), and Battery.
Remove the Keyboard Cover.

Unfasten the Keyboard, LEAVING the Keyboard Cable ATTACHED to the motherboard. Roll the Keyboard over, and lay it upside down on the Palm Rest Cover,

http://support.dell.com/support/edocs/systems/ins1420/en/SM/display.htm#wp1129771

[ NOTE*
Two Philips head screws at top of Keyboard. After removing, lift the top of the Keyboard up a little, slide it a LITTLE towards the Display Panel.
DO NOT lift it straight up at first.
There are 3 plastic tabs on the bottom of the Keyboard, that slide into the Palm Rest Cover. If you pick it straight up you will break those tabs off ]

In Removing the Display Assembly, note where number 1 points to.
This is the Display Panel Cable's connection, TO the motherboard.

Note where number 2 points to. Those cables going to the Mini-Card Antenna, HAVE to be reconnected, right back to the SAME terminals on the Mini-Card. Make a mark on the cables, and matching marks on the Mini-Card.

Use the instructions in Removing the Display Bezel.
Use the instructions in Removing the Display Panel.

View the last illustration in Removing the Display Panel.
Note how the Display Panel Cable attaches to the Display Panel, and Screen Inverter

Number 2 points to the connection at the back of the Display Panel
Number 6 points to the connection to the Screen Inverter
The Black connector that is not numbered at the bottom, is the motherboard connector of the Display Panel Cable.

This is a better view of the screen Inverter,

http://www.ebay.com/itm/Dell-Inspiron-1420-1421-LCD-Inverter-Backlight-Combo-/370274752470

Display Panel Cable checks out? Look at the screen Inverter. This small circuit board is located at the bottom of the Display Panel, and behind the Display Bezel. Closer look at link listed above.

Is the cable coming from the Display Panel Cable, plugged in tightly to it?
Does the screen Inverter look damaged?

Post back in a Comment, and we will go from there.

My pc is booting but no display


Did you check your monitor with other system or individually. If it works fine in these conditions then the issue belongs to your pc.
First of all, you have to confirm that is it the problem of VGA itself or the motherboard. For this, you have to see that does system beep when you start it because system with beeps having the error and the beep sound with continuous or 2-3 beeps relate with different issues. I am going to write down the beep conditions.

1 short beep Normal POST - system is ok 2 short beeps POST Error - error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem 1 long, 1 short beep System board problem 1 long, 2 short beeps Display adapter problem (MDA, CGA) 1 long, 3 short beeps Enhanced Graphics Adapter (EGA) 3 long beeps 3270 keyboard card

have you tried to isolate what the cause of the problem? first check the video card if is properly inserted into the slot, and check the memory, and cable from CPU to monitor if it is connected properly. then boot your system. And try to observe this beep error code this might help you locate where the problem is.
