Re: Compaq v6000 lights on but no display
no external...
Potentially. The GPU is required to display graphics, right? But it is not the only factor. Did you interfere with protective hardware measures (Hide modes this monitor cannot display, Desktop Window Manager, etc.)? These should not be touched, and if you do, you need to use safe mode or VGA mode, which will load basic drivers and make your screen look funny. But that's what it takes, so go for it.
Testimonial: "if would have been that i could have seen the bios at least"
You can get the wireless drivers in the laptop itself. U need to type in the start search as recovery manager and when the window is opened, click on the advanced options and select the option hardware driver installation. Search for the sound driver and select it and it get re-installed. If this doesnt work try to go to hp.com and select support and drivers and enter the product number of the laptop and follow the onscreen instructions. Thanks and Regards Honey
You could be having a problem with your power source....(not the plugin) but the actual power unit inside of the laptop. Or could be dirty inside and sometimes they get touchy with a lot of dust build up. Try cleaning out the inside of the laptop be removing some panels on the bottom and the keyboard. Try using a can of air to blow the crud out.
You can also take it to a shop and have them test the power source.

Have you tested this laptop using an external monitor? If your laptop works good with an external monitor, it means your laptop screen is dead and needs to be replaced. If the external monitor displays black screen , it means there is something wrong with the GPU and or motherboard.
hi
You can make test with an external monitor, if image appears, it will be necessary to replace the LCD and no image appears, will have to replace the mother board
Normally you can switch between internal and external screen by holding the fn-key Down while hitting one of the function keys with a Screen symbol on (f7 or f8)
The graphics chipset, or graphics I.C., is properly called the G.P.U. Graphics Processing Unit. The GPU, just like a Processor, is mounted to a small printed circuit board, which is the interface used to connect the GPU, to the motherboard.
[ Top View. The black rectangle with Nvidia NF-06150-N-A2, is the GPU. The greenish square around it, is the Printed Circuit Board. PCB. The little white rectangles with the silver looking band, in the middle of them, are ceramic capacitors ]
The above is the GPU for the HP Compaq Presario V6000 series, of Notebook PC's.
The Compaq Presario V6000 series of Notebook PC's, has a graphics chipset overheating problem. Also affects the HP Pavilion v2000, Pavilion v6000, and Pavilion v9000, series of Notebook PC's.
The cooling components for the v6000 series, is a Cooling Tube, Heatsink, and Fan Assembly.
Fan Assembly (Black) to the right. Fan inside a 'D-shape' shroud. At the top is the black rectangular finned -> Heatsink.
The slightly flattened copper tube is the -> Cooling Tube. It is sealed on both ends, and filled with Nitrogen.
The first little aluminum looking tab, away from the Fan Assembly, and on the Cooling Tube, sits on the GPU. It is TOO small in surface area. The reason the GPU overheats.
The next small metal plate that is X-shaped, with four mounting screws, sits on the Processor.
Put your mouse in the middle of the photo, then move around to enlarge.
Fan Assembly (Black) to the right, come to the top left corner of it. To the left of the top corner, and mounted to the Cooling Tube, is a copper rectangular plate. This small rectangular copper metal plate, sits on the top of the GPU.
Coming further to the left of that small copper plate, is the one that sits on the top of the Processor. Has an X shape with 4 screws in it, on the outside. Inside the black rectangle is the small copper plate, which sits on the Processor There is some grayish Thermal Paste that has been leftover.
Heat is absorbed by the two small metal plates, sitting on the Processor, and GPU. The heat is then absorbed by the Cooling Tube.
The Cooling Tube transfers the heat to the Heatsink. The Heatsink absorbs the heat in the middle of it, and radiates the heat away from it by the tall, thin fins.
The Fan Assembly helps carry heat away from the Heatsink's fins.
With constant repeated overheating, the mounting for the graphics chipset to the motherboard, develops a bad contact. bad contact of graphics chipset to motherboard.
The graphics chipset is mounted to the motherboard, with a BGA surface mount. Ball Grid Array. To explain the BGA surface mount compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket.
The bottom of the Processor has contact pins. 478 of 'em. The processor socket has matching socket holes,
With a BGA surface mount there are no contact ->pins, nor socket holes. In place of the contact pins are Solder Balls. In place of the socket holes are Copper Pads. (Gold plated also)
The graphics chipset is set onto the motherboard, with the Solder Balls lining up on the Copper Pads.
Heat is then applied at a specific temperature, and length of time. This solders the graphics chipset to the Copper Pads. Which in turn solders the graphics chipset to the motherboard.
Constant repeated overheating causes the solder joints, (solder connections), to partially melt. Then when the laptop is turned off the solder joints re-harden. This causes Cold solder joints, and makes a bad contact of graphics chipset to motherboard.
1) Laptop OFF, monitor OFF, connect a VGA monitor to the laptop. Connect to the VGA port on the left rear. You can use a CRT type of monitor, (Looks like small TV), or a flat LCD screen monitor if it has a VGA cable.
Example of a VGA cable, and VGA connector, (VGA port on laptop),
2) Turn the monitor on. If a CRT type allow it to warm up. Turn the laptop on. By factory default the display should be 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 the Fn key down, and hold it down. Tap once on the F4 key. The F4 key is the Display Toggle-Over key.
No display on external VGA monitor? Hold the Fn key down again, and tap once more on the F4 key.
Still no? You have problems with the mounting of your graphics chipset, to the motherboard.
If it is that you Do have a display on the motherboard, then the problem is the video cable, or screen Inverter, or LCD screen. Post in a Comment if you get a display on the external VGA monitor, and we will go from there.
This is one tech's method to fix the problem. Not repair, FIX. (Not advertising for this guy, just for reference of method )
5 minute video showing a BGA Rework Station. Helps to understand what a chipset looks like that uses a BGA surface mount, and the BGA surface mount process itself,
V6310US (offically retired at HP = no support)
first is carbon dating the thing, 2008 h3ll deal.
answer is (was) 2007 made, 10 years old now
and is in fact subject to the SOLDBALLS from H3LL failures
(aka Nvidia horror GPU)
does it turn on, main battery out, (hint they short and overload it)
yes,/no
does the fan turn and not packed in lint as all are this old.?
test 3: try a new coin RTC battery yet, for $3 ,if this battery goes dead so does BIOS go NUTS, (even black screens of *****)
hint the GPU dont just fall out like my great HP8540w does.
no, low end PCs its on the main board, soldered down
no ,you wont magically get reflow to work. sorry.
if you twist the case or press ******* the J key
will the PC turn on (fan on?) hint, that is tech trick.
rtm? see where that is>? free book no scalping here, !!!
PDF page 129 covers simple RTC swap in, do that now.
this laptop came as Intel based (CORE) or AMD based processors. wild differences. that.
onboard, video GPU is,, was... this.
NVIDIA GeForce 7150M (i see folks showing this failed)
sorry for you if it's a bad mobo, $$$
the 15 to 20 causes of Black screens of ***** and tests. to find it.
I would start with using the Restoration Disk, and when asked do a Non-Destructive restoration.
[Don't have one? Go to HP Support on the internet, then to Contact HP. In the US the disks are free. The shipping and handling is not. $17 for a 5 to 7 day ship, $24 for a 2 to 3 day ship. The designation Presario v6000 just means your computer is one of the Presario v6000 series. The EXACT product number is on the bottom of your laptop. It's in the white Service Tag, and to the left of P/N. Write it down, have it ready to tell the nice people at HP Support. PS. Calling in the US is free. It's a toll-free number ]
Past this I would look into seeing if the Display Cable has become slightly disconnected, or is damaged.
The top cover of your laptop, the LCD screen, the metal frame around the LCD screen, and the frame around the LCD screen in front that you see, (Bezel), is the Display Assembly.
Coming out of the body of the laptop that you do not see, is a Display cable. (And the Wireless Antenna Cable)
Opening and closing the laptop can cause this cable to become disconnected, (Usually slightly), and/or damaged. (Yes, I know. Who designed this?)
To lead you into reconnecting the Display cable, is going to be lengthy. I don't know your skill prowess, but repairing the cable may be more than you wish to take on.
First you will need to download the Service Manual. It's free from HP Support.
I chose the Compaq Presario V6000AU for an example. All of the v6000 series should fall within this service manual.
On this page scroll down to the listing - Compaq Presario V6000 Notebook PC - Maintenance and Service Guide, and left-click on it.
This is a PDF file. The computer you are on now has Adobe Reader on it, which uses PDF files. I would suggest upgrading, (Free), to the newest version of Adobe Reader, if your computer does not have it on it. Adobe Reader 9.3.4
After you click on the above file name, it will take time for the file to download. You may just see a blank page until the file fully downloads. Advise be patient.
Page 146 deals with the Display Assembly.
[ NOTE* Before working on a laptop, ensure all electrical sources to the laptop are disconnected. Remove the AC adapter (Charger), and the Battery.
Also follow Anti-Static Precautions. If you do not know what Anti-Static Precautions are, please post in a Comment ]
Page 147 shows the Display Cable. Enlarge the page for clarity. (Use the Zoom In tool. The + sign at the top )
The above are the easy repairs. Past this point it gets pretty intricate.
[May be a problem with the graphics chip. The GPU.
The bottom of the GPU used, (Nvidia GeForce G0 6150. Integrated graphics. GPU is soldered to the motherboard), has pins on the bottom. Contact pins. The socket these pins insert into is a BGA socket.
Over time, and with the heat involved inside a laptop, the pins become slightly un-soldered from the BGA socket. This allows a bad connection.
If this is the problem the GPU chip needs to be reworked with a Reflow machine. Not a common piece of equipment in a 'Geeks are us' type of computer repair shop, if you catch my drift. Repair will be stated as replace the motherboard.
There are other problems that can be afoot, with no easy DIY solution.
There was a TSB about the motherboards on the V series describing severe video issues and Nvidia GPU failures. Many consumers got a motherboard replacement. Try using a laptop cooler in the meantime and see if that helps a little. Also try googling V6000 video and see how many others got nuked by this poor design.
I managed to find used & new laptops on this site, you can order them for free. Of course, these all complete machines, not just screens, and so their price is something about 500€, that's $750 or so.
HP has identified a hardware issue with certain HP Pavilion
dv2000/dv6000/dv9000 and Compaq Presario V3000/V6000 series notebook
PCs, and has also released a new BIOS for these notebook PCs, version
F.39 for dv2000/V3000, and version F.3D for dv6000/dv9000/V6000.
the board is clean, ill check the smds with the voltmeter
