Vertical lines on my compaq cq61


Problem is;

1) Bad graphics chipset,
or
2) Bad Video Cable, or loose connections,
or,
3) Bad screen Inverter,
or,
4) Bad LCD screen.

A) Graphics chipset:

(Chip and Chipset are slang terms for I.C.
Integrated Circuit,

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

The chipset, or I.C. used for graphics; is the graphics chipset.
More properly known as the G.P.U.
Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU )

Laptop OFF, monitor OFF, connect a VGA monitor; to the VGA connector on the laptop. (Port)
(Left side of laptop, if memory serves)

This is a General example of a VGA connector, (Port), and VGA cable,

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

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 allow it to warm up.
Turn the laptop on.
By factory default settings, the display should show on the external VGA monitor.
IF not;

You have 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

Press, and hold the Fn key down, and at the SAME time tap once on the F4 key.
(The F4 key is the Display Toggle-Over key)

Still no?
Hold the Fn key down again, and tap once more on the F4 key.

Same display on external VGA monitor (Red lines), suggests problem with the graphics chipset.
Good display on external VGA monitor means;

Problem with;
1) Video Cable
2) screen Inverter
3) LCD screen

If you find it is one of the three stated above, post back in a Comment; and I'll guide you step by step, in diagnosing.

Will require partial disassembly of laptop, but not very far.
Will also require an ESD wrist strap.
Average cost is around $3 to $6.

Example,

http://www.radioshack.com/product/index.jsp?productId=2103245

Needed to keep from Static shocking, the delicate hardware components inside the laptop.

[All power removed;
Loosen Keyboard, and roll over out of the way. Do NOT disconnect Keyboard Cable.
Remove Keyboard Cover.
Remove Display Bezel.
Remove screws that hold LCD screen to Display Cover, and check Video Cable connections to back of LCD screen.

The plastic frame in front of the LCD screen, is the Display Bezel.
Laptop closed the top cover is the Display Cover.

Just basic instructions. Like I said, I will step by step you through it, if you wish ]

[Primer:
An LCD screen cannot produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight can be a CCFL (or more than one), or a series of LED's.
(Light Emitting Diode)

The Compaq Presario CQ61 series of Notebook PC's, uses a single (1) CCFL.

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

Average thickness is 2mm. That is a little more than 1/16th of an Inch, or about the width of this capital letter -> O <-

Average length is almost as long, as the LCD screen is in height.
View the last 8 photos,

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

The screen Inverter converts the power (Electricity), from the laptop; for the LCD screen, and Backlight.
Backlighting that uses CCFL, uses a screen Inverter.

Backlighting that uses a series of LED's, May or May Not use a screen Inverter.
It seems when the LED technology first came out, they did.
Later designs do not seem to.

What is the poblem of a laptop with the screen goes up and down...


1) Video Cable:

The Video Cable connects to the top of the motherboard, in an area under the Keyboard, or Switch Cover.
From there it goes under the left Hinge, and up into the Display Assembly.

Routing under the left Hinge, and normal repeated opening, and closing of the laptop, may cause the Video Cable to become pinched. This can cause loose connections, and/or damage to the Video Cable.

Average example of a Video Cable,

http://www.amazon.com/LotFancy-Notebook-Compatible-50-4AQ08-101-50-4AQ08-001/dp/B005GB9GT4

Click on the view to enlarge it.

The video cable connection may be loose at the motherboard side, and/or at the back of the LCD screen, in the Display Assembly.

Procedure for checking is to Physically, see if the connector/s is tight.
Visual inspection alone will NOT do.

The tiny wires inside the sheath of the Video Cable, may be damaged. Stretched/Broken. Could have an intermittent contact of the broken wires, and this causes a poor video signal.

2) Screen Inverter:

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

A Backlight can be a CCFL, (Or two of them), or a series of LED's
(Light Emitting Diode)

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

[Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height ]

A screen Inverter is used to convert the electricity from the laptop, for the LCD screen, and Backlight.
A laptop that uses LED's for a Backlight, most of the time does not use a screen Inverter.

Primer over.

A failing screen Inverter will show the symptoms you describe, also.

3) LCD Screen:

If the Video Cable proves to be OK, (Continuity check with multimeter, and also have an assistant gently wiggle the cable while you are checking (OHM's), to see if there is an intermittent break), and the laptop's Backlighting is LED's, then the problem is the LCD screen.

What is the laptop manufacturer name, and model number?
Model number is on the bottom of the laptop. Most of the time in a sticker. (And close to the Windows product key holographic sticker)

The LCD screen is faulty and will need to be replaced, go to www.ebay.com Type: make and model refine search to screen, first! hook a spare monitor to the video output usually on the back, if picture okay! the above mentioned needs to be changed, but! if both show the same symptom it is the video graphics card that is part of the motherboard.

White horizontal lines running across laptop screen


I did not see any white lines, Simon, in the screenshot.
Just sayin'.
(Glad you tried to post it though!)

The problem is caused by a faulty Video Cable, or it's in the Display Assembly.

However, you better start the diagnoses with using an external VGA monitor, and see if the lines show up on the external monitor, also.
This would indicate a bad graphics chipset.

For most people that would mean replacing the motherboard.

A) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA connector, on the Left side of the laptop.

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

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

You can use a external VGA monitor that is a CRT type, (Looks like a small TV), or a flat LCD screen monitor with a VGA cable.

A1) 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 monitor.
IF Not,

Press, and hold down on the Fn key, (Bottom left of Keyboard), and at the same time tap on the F5 key. (Top of Keyboard)
{The F5 key is the Display Toggle-Over key }

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 F5 key.

Graphics look good on external VGA monitor?
Your graphics chipset is good.
Problem is Video Cable, or in the Display Assembly.

B) Video Cable: (LVDS Cable)

http://www.insidemylaptop.com/disassemble-acer-aspire-7551g-laptop/

The above is for an Acer Aspire 7751G, but it is close enough to the 7750G models, and info should directly crossover.

Scroll down to Step 17.
The Video Cable connection to the motherboard, is shown by the yellow arrow at the Top Left.

Note, although the photo is less than, the routing of the Video Cable.
It goes through the Left Hinge.
(Then into the Display Assembly, and connects to the back of the LCD screen)

With normal opening, and closing of the laptop, the Video Cable could be pinched, or have been pinched. Could have been pulled on.

You close the laptop, the cable is slightly pinched in the Hinge, and it pulls loose from the motherboard connection, AND/OR the LCD screen connection.

Doesn't take much of a loose connection. In fact it's hard to discern with the human eye, sometimes.
Make sure this motherboard connection is tight.

You have to open the Display Assembly, and check the Video Cable connection on the back of the LCD screen.

Doesn't look loose? Try to plug it in tighter anyway.

Check the connection of the wire/s from the Video Cable, TO the screen Inverter.
The small circuit board behind the Display Bezel, (LCD Bezel), and mounted to the bottom of the LCD screen.

When on the motherboard side, the side of the Video Cable that runs through the left Hinge, is there any apparent damage? Damage to the sheath of the Video Cable?

If there is, chances are the tiny wires inside the Video Cable, are damaged also.
Check with a multimeter. Perform a continuity test of Each wire.

C) Display Assembly:
Video Cable checks out then the problem is in the Display Assembly.

1) Screen Inverter:

http://www.sparepartswarehouse.com/Acer,Aspire-7700-thru-9800,Laptop,Inverters.aspx

http://www.insidemylaptop.com/replace-broken-screen-acer-aspire-5745g-laptop/

Not your model, granted. Posted for the Display Assembly dis-assembly pictorial guide.

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

A Backlight is a CCFL, or a series of LED lights.
Your laptop uses a series of LED lights for the Backlight.

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

A CCFL requires a screen Inverter.
A screen Inverter converts the power from the laptop, for the Backlight, and LCD screen.

NOT all LCD screens that use LED lights as a Backlight, use a screen Inverter. I suspect yours does not, as I can't find a listing for a screen Inverter, for it.

http://www.laptopscreen.com/English/section/FAQ/1245191276/Correct%20backlight%20type%20for%20your%20new%20screen/

This would mean that if the Video Cable proves to be good, the next step is to replace the LCD screen.

Shop around for the best price, AND make sure it is a direct replacement for yours.

The screen is white >>>


Your inverter board is OK otherwise you will not get any light on the screen, there is only one inverter board, Check the flat ribbon cable connected to the LCD panel (locate behind the LCD panel), when this connector comes off you will get white screen.
