Staying up late at night? Excuses why there are DVD's all over the place? Refrigerator door is left open?
Any mention, why there is an M1A2 Abrams tank sitting in the living room?
OH,.......I'M JUST KIDDING!
A) Laptop on, take a flashlight, and shine at the LCD screen; at various angles
See faint images?
(Ah HA! Busted! Somebody's holding a thin curtain up inside the Display Assembly!........................Not funny?..................K)
B) I would like you to connect a VGA monitor, to the VGA port (connector) on the laptop. This test will show us if the laptop is working okay, but the problem is the Video Cable, or inside the Display Assembly.
It also tells us if the graphics chipset is good.
Laptop OFF, monitor OFF, connect a VGA monitor; to the LEFT side of the laptop; and to the Blue VGA port.
This is a general example of a VGA connector (port), and VGA Cable,
Go to 0:45 The green rectangular object that was behind the Display Bezel, and is mounted to the bottom of the LCD screen; is the screen Inverter. As you can see it's a green colored, rectangular circuit board.
Just showing you location. If it is decided to replace it, I will step by step you through the procedure.
Now a small primer if I may;
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) As far as I can tell the Aspire 5532 uses one (1) CCFL for a Backlight,
A) Graphics chipset B) Video Cable C) screen Inverter D) LCD screen
Let's diagnose, and find out.
A) Graphics chipset:
To start off with, the Pavilion dv5000 series of Notebook PC's; is NOT known to have a problem with the graphics chipset. The Pavilion dv2000 series, Pavilion dv6000 series, and Pavilion dv9000 series; does.
1) Laptop OFF, monitor OFF, connect a VGA monitor to the VGA port; on the laptop. The VGA port is on the Left side of the laptop, and located towards the rear.
This is a general example of a VGA connector (port), and VGA Cable,
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:
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
Press, and hold down on the Fn key, 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.
No display on external VGA monitor, suggests a problem with the graphics chipset. (Most of the time it is a problem with the Mounting, of graphics chipset TO motherboard. If this proves to be your problem, state in a Comment )
Display on 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 Switch Cover.
(Left side. Switch Cover is the plastic cover above the Keyboard, and below the LCD screen. Has the Power On Button, LED indicator lights, etc in it)
It then loops by the left Hinge, and goes up into the Display Assembly. There is a small separate wire that comes from the main Video Cable, and connects to one side of the screen Inverter. The main part of the Video Cable goes on, to connect to the back of the LCD screen.
Click on image to enlarge. The wide connector you see at the top/left, connects to the back of the LCD screen.
The wide connector at the bottom/right, connects to the motherboard. The single cable (Wire) coming off at the bottom, connects to one side of the screen Inverter.
Just due to normal repeated opening, and closing of the laptop; the Video Cable may become pinched. This leads to it being pulled on, and may also lead to damage of the Video Cable. (Stretched/Broken wires)
Procedure is to Physically check the connections of the Video Cable. Visual inspection alone will NOT do. You need to physically see if you can plug the connection in tighter.
1) ALL power removed. Remove the AC adapter (Charger), and Battery. 2) Remove the Switch Cover.
[Switch Cover is just that. A Cover. I will give a link to a free Service Manual from HP Support, towards the bottom of this solution ]
Try to plug the Video Cable connection at motherboard, in tighter. Once done reinstall the Battery, and attach AC adapter. Plug AC adapter into power. Turn the laptop on.
Still no? Turn laptop off. (Hold down on Power On button) Remove ALL power again.
This time check the Video Cable connections at screen Inverter, and back of LCD screen.
The plastic frame in front of the LCD screen is the Display Bezel. Example,
Service Manual indicates to remove Display Assembly from laptop, in order to remove Display Bezel. IMHO this = NO. I think you can remove the Display Bezel, without having to remove the entire Display Assembly.
This video details removing the Display Assembly. Shows replacing the LCD screen.
What my concern is with removing the Display Bezel, is the integral Hinge Covers that are a part of it.
I believe the Display Assembly can be tilted far enough back, that the Display Bezel can be removed, and carefully ease the Hinge Covers out/off at the same time.
Why not just remove the Display Assembly? A whole lot less stuff to reconnect, after you have checked the LCD screen connection of the Video Cable, and screen Inverter connection.
After disconnecting the LCD screen from the Hinge Brackets, you just tilt the LCD screen forward, and check the Video Cable connection. Then slightly tilt the Display Cover back, so the LCD screen can rest against it, and reinstall power.
Connections are plugged in tighter, and this proves to Not be the problem, go on. (Don't forget to remove ALL power again)
The Screw Covers are made of synthetic rubber, or plastic. They are held in place by a type of rubber cement. I like to use a computer pick, (Much safer than a blade!), and lift up at the base of the Screw Cover.
I also like to GENTLY stick them to the Display Bezel for safekeeping. (They like to stick to the tool, your fingers, and it seems passing cars. "Oops, dropped one. Where'd it go? Hmmmm)
If you are careful with them you can reuse them. (Doesn't stick anymore? Apply a TINY dab of rubber cement to them, with a toothpick)
Screws removed, I suggest cut a piece of thick construction paper, that just fits the inside edges of the Display Bezel. Helps prevent scratching the LCD screen, from your fingernails, when you go to flex the Display Bezel, and remove it
The LCD screen is an Assembly of layers. They are held in the factory aligned position, by the metal Screen Frame which surrounds them.
There are screws that hold the Hinge Brackets TO the Screen Frame, and there are screws which when removed, will take the Screen Frame apart.
ONLY remove the necessary screws which hold the Hinge Brackets, TO the Screen Frame!
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,
[ 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 normal. Your monitor has a VGA hook in for regular definition. What it is doing, the monitor always by default looks for the VGA hook first. On my desktop it does the same thing until it finds a signal on the DVI.
have you checked your PC output?
check it with another screen (whichever)
and see if the output signal is good
if soo check the cable and connections to your LCD
check your PC for software configuraitions:
1) TV output
2) good resoulotion
3) media borad is strong enough to handle this LCD
if all is good then maybe the TV borad is sending a low voltage/current then the LCD can see
