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!
1) Have you installed new drivers or software or drivers? If so, remove them and restart the computer.
2) Try applying pressure with your fingers on top of the screen. If the band dissapears or dimishes, you may have a broken screen and it will need to be replaced.
It sounds like the camera may need to be reseated on the motherboard. Could be a loose connection with the cable. You will need to get the keyboard and power strip off and access the cable from there. The cable runs from the right side of the display across the palmrest to the center lower part of the motherboard and plugs into a small flat socket. To get the power strip off, remove the battery, next...there are several screws you will see, all of those screw need to be removed, there may be 5-6. Now take the access cover off the memory/wireless compartment. There is a screw inside a tube marked with a keyboard symbol, this screw has to come out. Now turn the laptop over and pry the right side of the power strip up gently, just position it forward toward the screen just enough for the keyboard to flip up. Now shift the keyboard toward the screen so that the hold down tabs at the lower part clear the palrest. Now under the keyboard is the flat socket holding the keyboard cable, push the retaining tabs on both sides of the socket toward the screen, this releases the cable. Lift the keyboard free. Youcan leave the power strip where it is, it does not to be removed. Now look to the right side of the display at the right hinge. The flat cable is the camera cable, it is usually bundled next to the two wireless antennae leads. Follow the flat cable down to where it plugs into the motherboard. Pull the plug out and give the socket a blow of air to clean dust and debris. Now plug the cable back in and make sure it seats well. Put everything back together, go to HP and make sure you download the "Cyberlink" Youcan software drivers and the camera should work fine.
this thing happened in my laptop also i got green screen fully then when i hit it behind the screen it was gone but comes many times then again i would hit later on the screen was completly lost then had to replace the screen yous is a starting period so go to a nearby computer service and fix the screen
This sounds like you have a damaged LCD screen or dead pixels. I don't know anyway to solve this besides changing the screen. The only other thing would be a motherboard problem meaning u have to change that but most likely its the screen.
Place you cursor on a blank spot on the black area, Hold the left mouse/touchpad button down and drag it back down to the bottom of the screen. That should get you back to where you want things to be. If that fixes it, please return here to rank this as solved. If it doesn't, let me know and we'll see what else we can come up with. ;o) Ron-
