Question about HP L1702 17" LCD Monitor

1 Answer

Need help with connector on a 1702 HP LCD

July 29, 2008

I have just repaired a HP LCD screen Model 1702 17". The HP has the same caps as the Compaq 15" LCD screen Model FP15 Model Number PE1233 Product Name P9618C.

This LCD has 2 boards, one 'power-backlight board' reference 715L1034-1 and one 'processor board'. This 715L1034-1

The 'power board' 715L1034-1 was not working I replaces all the caps and found 2 loose solder joints and 1 joint were the circuit was peeling off the board.

I did not have a problem with replacing any of those good old HERMEI caps my issue is with the 'processor board' (the smallest of the two). It seem that the cable that comes from the board that is 1 4/16” (connector) and it go’s to the top of the LCD panel (connector) 1 1/2”.

All the other connector ether goes in one way or snap in or both this one does not. The connector that comes for the 'processor board' is smaller than the connector at the top of the LCD panel.

This smaller connector from the 'processor board' has several small flat gold contacts that fit some how in the LCD contact. Now I can slide this smaller connector in the other connector from lift to right about 1/4" (seeing that they are of different sizes) without it snapping in, so how do I find out if it has to go to one side or the other.

I hope that I was clear on my description of the contacts. I can’t send picture seeing that my camera is not working. If anyone can help I would appreciate it as everything is on hold for now. John

Hp 1702 wont start

That looks like the problem. I have LCDs handed to me for wrecking and I always find the power supplies go bad. If you replace the Caps, check and make sure that none of the oil has run to other items on the board. This would mean you will have to replace more items as the oil will short out the other components. Don't worry about your english, I can make you out fine. Replace the caps and try it out.

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.
