[ 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 ]

(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)

HP 1702 monitor pin-outs


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.
