Sorry help me. I am looking the diagram for connector vga from lcd VA 721 VS 10047. The connector that i have has: 1. red, 2. grey, 3 blue. LCD manufactured in 2004 Thank you

you may have encountered a VGA cable not properly installed to the VGA ports....try to reconnect the VGA cable,properly installed from the VGA port of the LCD to the onboard VGA port of the motherboard and restart computer... less pressure applied to each and every end of VGA connectors to VGA ports may sometimes affect the display of the screen causing to red, pink blue screen output....hope this help...

I would like you to try using HP's Part Surfer.

1) Put your Product Number, or Serial Number in the Quick Search box,
(P/N = Product Number.
S/N = Serial Number.

{DO NOT give out the serial number on a public forum such as this. Only on the HP website}

2) Then click the blue down arrow on the right side of the - Select a country or region - box, and click on your country.

3) Finally go back to the Quick Search box, and click on the side arrow to the right.

Post back in a Comment as to your findings.
We'll go from there.

On the back of the LCD screen is the HP part number.

Awaiting additional questions. Please post in a Comment.

[ P.S.
You can disconnect the LCD display, and use an external VGA monitor, while you wait for the replacement LCD screen.

1) Laptop off, VGA monitor off.
2) Connect the VGA monitor to the Left side of the laptop.
( External monitor port. The VGA connector resembles this one,

http://en.wikipedia.org/wiki/File:SVGA_port.jpg

3) Turn the VGA monitor on. Wait for it to 'warm up'.
Turn the laptop on.

If the display does not automatically go to the external monitor;
Press, and hold down on the Fn key.
Tap the F4 key.

(The VGA monitor can be a CRT monitor, {Looks like a small TV}, or a flat LCD screen monitor that has a VGA connector, and a VGA cable ]

Here's some wiring diagrams:
First according to pin: http://hot-flash-games.com/web/vga%20cable%20pin%20connection-2875.html
And in this post you have pinouts according to standard color: http://www.diyaudio.com/forums/diy-projectors/30458-vga-pinout-wire-colors.html

that's all oh yes you also have a ground wire from connector base to connector base.
Hope this helps. So from these two, you should be able to figure out witch wire is witch. Let me know if you need more detailed information.

(Green Power LED will go Green the Go Off) Brief rise then collapse of the Vs and Va voltages.

This indicates a "Load" on the line.

Pull the CN-64 connector feeding Vs/Va voltages to the X-SUS.

Take an ohmage reading from the Va and Vs lines on each PWB.

This means you have to read the Connector on the Power Supply and the pulled connector going to the X-SUS.

See if there is a low value. Low value indicates a defective PWB.

Normal reading should be infinity. (Using the diode mode on the DV/Voltmeter, there will be a brief charge

time, then infinity.) In other words, it may appear as a low ohm reading, but should rise to infinity or open.

(Also not, if there is a charge on the line, the meter may show a low. You must Pull the CN68 connector and take

a reading again).

The line should now be infinity when reading the Power supply pins for Va and Vs and when reading the

connector going to the X-SUS PWB.)
If a Low is see on the connector, pull the CN32 Connector. (Bottom right hand plug on the Y-SUS PWB)

Does your laptop have a VGA port on it? Its a blue port usually. If so, try connecting an external monitor from a desktop to see if it will give you a display. If this works it is probably the inverter on your laptop screen. You will need to take it to your local repair shop to get it checked out.

pin no 1 - Red colour signal (Red colour wire)
pin no 2 - Green colour signal (Green colour wire)

You will have to buy a 13 Pin Din Male Connector cord. Use the break-down below to help with reconfiguring.

Okay...after a bit of trawling the net I found an almost correct pin out. It was not identical to my broken connector however after a bit of checking, I found that all the screens on the cable were common so I wired the connector as follows and all was well! :- 1 Pink 2 Grey 3 Light Blue 4. Violet 5. Link to 6,7, and 8. 6. as above plus a link to the drainwire next to the foil screen. 7. Link to 8,6 and 5 8. Link to 7 and 6 - just use some solder! 9 Dark Blue 10. Red 11. Black 12. Brown 13. Orange 14.Yellow 15 Green I used a diecast 9 way backshell and tied the cable braid screen to that so everything properly screened. Plugged it in and away it went! Hope this is helpful in the future. Best regards Victor.
