Question about Edirol UA-4FX External Sound System

1 Answer

Compaq V5000 laptop

I am having trouble with my LCD screen. The top 1/4 works but the bottom
3/4 does not. If I pinch the far left side of the screen as tight as I can it frees up to use curser for the full screen. Otherwise,I can only use the top 1/4. Any idea on how to fix this??

Much thanks, Trudi

It may either be connection of the LCD to the flex cable, (IF YOUR LUCKY), or the TAB welds on the board on top of the LCD are bad.

If you want to attempt this you will have to remove the screws on the plastic that houses the LCD and separate the bezel front and back. Screws hold the lcd to the back bezel. make sure the ground is attached and the cable is securely in place.

White screen on laptop

Long read ahead Naveen.

Check to see if the problem is the;

A) Graphics chipset,

B) Video Cable,

C) Screen Inverter,

LCD screen,

(Not advertising, but on another note; you can buy the whole laptop for $50 USD, )

A) Graphics chipset:

Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port on the back of the laptop.
This is an example of a VGA connector (port), and VGA cable,

Scroll down a little for VGA cable example.
You can use a CRT type monitor (Looks like a small TV), or a flat LCD screen monitor of 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:

There are at least 3 display options;
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 F3 key. The F3 key is the Display Toggle-Over key.
Still no?
Hold the Fn key down again, tap once more on the F3 key.

A good display on the external VGA monitor means the graphics chipset is OK.
A white screen on the external VGA monitor, means a problem with the graphics chipset. More than likely the Mounting to motherboard, of the graphics chipset. (BGA surface mount)
If this is the problem post back in a Comment.

A good display on the external VGA monitor, means the problem is the Video Cable; or inside the Display Assembly.
(Screen Inverter or LCD screen)

B) Video Cable:

The Video Cable plugs into the motherboard, in an area under the LED Button Bezel, and right next to the Left HINGE.

[LED Button Bezel is the strip of plastic below the LCD screen, and above the Keyboard. Has LED indicator lights in it, etc ]

It then leads up into the Display Assembly, where a small separate cable connects to one side of the screen Inverter, and the rest of the cable connects to the Back of the LCD screen.

Just due to normal repeated opening, and closing of the laptop; the Video Cable may become pinched.
This allows it to be pulled on, and/or damaged.
(Stretched/broken wires)

ALL power removed, AC adapter (Charger), and Battery; the connections for the Video Cable should be checked.
Motherboard side, screen Inverter connection, and LCD screen side.

Motherboard side connection:
1) Remove the LED Button Bezel.

Two screws (Philips) are removed from the bottom of the laptop, and the LED Button Bezel is CAREFULLY pried up, and off.

Details are in Page 91 in the Service Manual, which I will include at the last of this solution.
I will refer to the page number from now on, for the specific component removal.

2) Remove the Keyboard. Page 93.

I state remove, but do NOT unplug the Keyboard Cable from motherboard connector. Just unfasten the Keyboard, roll LCD screen side towards you, and lay upside down on the Palm Rest Cover.

You MUST physically check the connection for tightness. Try to plug it in tighter.

LCD screen side connection:

Disassembly of the Display Assembly, is not shown in the Service Manual. (At least I couldn't find it)
REMOVAL of Display Assembly is.
So I will guide you step by step. I do not believe the Display Assembly has to be removed, in order to remove the Display Bezel.

The plastic frame in front of the LCD screen is the Display Bezel.
Looks like this removed,

From what I can see, there are four Philips head screws to remove, from the Display Bezel.
There is a Screw Cover at the Top Left, and Top Right to remove.
The is a Screw Cover at the Bottom Left, and Bottom Right to remove also.

The Screw Covers are made of synthetic rubber, or plastic.
I use a computer pick, and lift up at the base of the Screw Cover, where it meets the Display Bezel.

The Screw Covers are held in place by a type of rubber cement.
If you are careful you may be able to reuse them. If they don't stick again, apply a TINY dab of rubber cement with a toothpick.
I LIGHTLY stick them to the Display Bezel for safekeeping.

Remove the 4 Philips head screws. (No.1 Philips screwdriver, or No.1 Jewelers Philips screwdriver)

The Display Bezel has TABS going around the exterior perimeter, of the inside edges.
The Display Cover has matching LATCHES that the Tabs snap into.

I suggest cut a piece of thick construction paper, to JUST FIT the inside edges of the Display Bezel, and lay on LCD screen.
(Display Assembly laid as far back as possible)
This will protect the LCD screen from your fingernails.

The bezel is flexible. Come to the inside edge (LCD screen side), of the right side of the Display Bezel.
Lift the edge up with a fingernail, until you can slide a fingertip underneath.
Can't get in? Move over. You are at a Tab/Latch.

Bezel lifted up with one fingertip slid under, move over with the other hand, and slide a fingertip under. Flex the bezel up a little, and move towards the Top.
By now you should hear a Tab/Latch snap loose.
Sounds like you are breaking something.

(Do use CARE! The bezel can be broken, but not if you are gentle, and go slow)
Keep popping the Tabs/Latches loose, going around the Top, then Left side. By the time you come around the Left side, the entire Display Bezel should pop loose.

(At the TOP. You may have to slide the Latch over to the open side, to get the slot in the Display Bezel to clear, if a Latch is used)

Not your laptop, and uses more screws. Just a basic 'hands-on' guide I thought may help,

More to follow in added Comment.

Horizontal black line at bottom of laptop screen/ Compaq Presario C700

Alan, let's diagnose;

1) Do you have access to a VGA monitor? (CRT style. Looks like a small TV)
How about a flat LCD screen monitor with a VGA cable?

Need to see if the problem is the graphics chipset, or the Video Cable, or inside the Display Assembly.

A) Laptop OFF, monitor OFF, connect the VGA monitor, to the VGA connector on the laptop. (Left side towards the Front)

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By default (Factory settings), the display should show on the external VGA monitor.
IF not;

There are at least 3 display options;
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, (Second key from left on bottom), and at the same time tap once on the F4 key.
(The F4 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 F4 key.

Display on external VGA monitor OK? Problem is the video cable, or inside the Display Assembly.

Line still on display? Problem is the graphics chipset, or it's mounting to the motherboard. (BGA surface mount)

Problem with Video Cable or Inside the Display Assembly:

Video Cable; Display Cable when referring to an HP, or Compaq laptop.

The Display Cable attaches to the motherboard, under the left side of the Keyboard, and towards the front. It then routes under the left Hinge, and up into the Display Assembly.

From there it splits, and connects to the screen Inverter, and back of the LCD screen,

{ In the photo; On the right side there is a wide connector, (Top), and a small connector, (Bottom)
The wide connector connects to the motherboard. The small connector connects to the screen Inverter.

The connector to the far left connects to the back of the LCD screen}

Just from normal opening, and closing of the laptop, repeatedly, the cable can be pulled on. It can also be pinched in the left Hinge, and be pulled on.
This can cause two things:

1) Can pull the cable so the connection at the motherboard is loose, or loose at the screen Inverter, or back of the LCD screen. Or all three.

I have repaired a few laptops whereby this was the problem. I also have a few users on here, who reported this was the problem.

You have to remove the Switch Cover, and partially remove the Keyboard, to access the motherboard side connection, of the Display Cable.
You have to remove the Display Assembly, and open it up, to access the LCD screen side connection.

You CANNOT just visually inspect the connections, and assume they are plugged in tightly.
You need to physically, make sure the connections are plugged in tight.

The Switch Cover is just that. A cover.
The Keyboard has a Keyboard Cable, that stays attached to the Keyboard, and is connected to the motherboard connector.

Therefore, when checking to see if just the motherboard connection is the problem; you can just leave the Keyboard Cable attached to the motherboard, and fire the computer up after physically checking the motherboard connection.

{ Flip the Keyboard over, and lay it down on the Palm Rest Cover.
Excuse me. Top Cover for HP and Compaq }

With the LCD screen, and screen Inverter connections, you can lay the LCD screen down on your 'work' table, and try it. This way you can try it to make sure it is the problem, before reassembling the laptop.

Otherwise you will be removing the Display Assembly again, and opening it up, again.

[This will all make more sense as you read on ]

The Display Cable can also be damaged. Visually check the sheath of the cable. ANY apparent damage, may result in damage to the tiny wires inside the sheath. (Stretched/Broken)

Test the wires inside the display cable for continuity. This is done with a multimeter set to OHM's. (1K)
If you do not have access to a multimeter, perhaps take it to a 'Mom and Pop' computer store to have it checked. Should only cost a few bucks.

Display cable connections are tight/ cable checks out?
Problem is the screen Inverter, or LCD screen.

The screen Inverter is checked with a Sensitive multimeter.
Read fairly expensive,

Perhaps the 'Mom and Pop' computer store again.

{ A screen Inverter, and an LCD screen are a MATCHED unit. If the Inverter is the problem, make SURE you get the correct one. Same thing with an LCD screen. Make SURE you get the correct one }

Screen Inverter checks out? Problem is the LCD screen,

[ALL of the parts shown are just for examples. NONE are for advertising ]

To Add:
An LCD screen cannot produce light,

Click on the monitor icon. (I also would click on -> No thanks)

An LCD screen needs an additional light source. A Backlight is the additional light source.
A Backlight can be a CCFL, 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.
In the next example look at the last 5 photos,

The Compaq Presario C700 series of Notebook PC's uses a single CCFL.

A screen Inverter converts the power from the laptop, for the LCD screen, and Backlight.
90 PERCENT OF THE TIME, the fault is a bad screen Inverter.

3) Click on one at a time -

Page 58 for the screen Inverter.

A) Remove ALL power. Remove the AC adapter (Charger), and Battery
B) De-static yourself before working on the laptop. Perhaps there is a large metal serving plate (Unpainted), you can set on the table, or a large metal knickknack. (Unpainted) Touch before working.

C) Use a multi-compartment container, for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
[If no multi-compartment container is available, you can substitute with a clean egg carton. Label each egg holder ]

SOME screws look VERY similar to other screws.
Advise do Not mix them up.

Need advice along the way post back in a Comment. I'm right here.

Broken touchpad on compaq v5000 series

Disassemble the laptop, down to where you can remove the top case cover, and get to the Touchpad. (AC adapter, {Charger}, removed, and battery removed)

Here's how:

This is, and the Manuals page for the Compaq Presario V5000 CTO laptop. (Even if it isn't your exact model, your laptop is part of the Presario V5000 Series, and this information transfers directly over)

On this page I would like you to click on ->
Compaq Presario V5000 Notebook PC - Maintenance and Service
Guide <- in blue.
It states that it's a 'guide', but it's a Service Manual, believe me!

This is a PDF file download. After you click on it, you may not see
anything happening for up to 30 seconds. Usually after 10 seconds
you will see the first page. I caution you to Not look through it, until it has fully downloaded. You may accidentally break the connection.
AFTER it has fully downloaded, you can save it to your computer.
This way you can burn it to a CD disk, and look at it anytime you want. (You can also delete it off of your computer, and free up harddrive space, plus you can put the disk in another computer, and view it as you work on your laptop)

To do this click on the Floppy Disk icon. This is in the upper header, and is the second icon from the left. Hovering your mouse over it will briefly reveal, "Click to save this file to your computer or another location"
If you do not have your downloads set to be saved to your My Documents folder, this pdf file will go to your desktop screen.

Suggest you start with Page 77 first, then on Page 125 (Base Enclosure and Top Cover), you'll find the info for removing the Top Cover. The Touchpad is in the Top Cover.

Lcd screen partially paralyzed

The problem is either the LCD display, or the ribbon cable/connector.
The laptop must be taken apart testing the lcd ribbon cable, replacing it or re-fitting it in place inside the connector.
If ribbon cable is ok, then LCD panel is faulty.
If problem disabbears when you push the laptop case, then it is probably the cable.
Go to a reliable computer repair shop and mention the problem, the cable is worth just a couple dollars, and the labour is around $80.
