Hello......can anybody give any solution for this problem : my VGA Cable disconnect from the 15 Pin gents connector of Crt monitor of philips model no. 107E61 I want to fix it but I could not understand...


These connectors come with 15 pins and 9 pins. But be carefull, the nine pin connecter uses a tottaly different color code. Thats for an oldschool gamepoort or midi connector. But I think the vga connector has 3 rows of pins total of 15. But the nine pin connector has probably two rowes of pins. And thats no vga connector, but an connector for an serial port.
If it has three rowes (see Fig-2 below) but uses 9 pins then its an RGB instead of VGA.

You're trying to use a proprietary part on a different computer.

The plug connector you have was made for a 8(?) contact pin plug connector. (Usually 1 pin is missing, for a 'Key' pin)

The Front Panel header on the mobo you're trying to use it on, has a 10-pin Front Panel header. (Again, 1 pin missing for a Key pin)

You need to separate those individual connectors.
Yeah, I know.

This involves trying to slice/saw them out, and there's Nothing dangerous about that! (Sarcasm)

Moving on............

The connectors in that female plug are female metal terminal connectors. Individual connectors. Example,

http://www.mcmelectronics.com/product/28-9420&utm_medium=Affiliate&ref=cj&utm_campaign=CommissionJunction&utm_source=CommissionJunction

The opening in the front, of course goes over the contact pin, in the Front Panel header on the motherboard.
The back of the connector, shown at the top; is crimped around the insulation of the wire.

The barrel shaped connector slides down into the individual socket hole, in the plug connector.

Looking at the Molex connector, observe the two 'Tangs' that stick out on either side. -> /

When the Molex connector is inserted into the plug connector's socket hole, the Tangs press against the sides of the connector.
When the Molex connector is at the correct depth, in the plug connector socket hole, the Tangs 'pop' out.

They pop out in small depressions, in the sides of the socket hole.
See how they angle towards the back?

If you slide the correct diameter of needle, down in the Front of the plug connector, (And in socket hole), you can depress one tang at a time.

Slides into the socket hole, right next to the Molex connector, and pushes down on the Tang.

Once depressed by the needle, lift up on THAT side a little.
Keeps the tang in a correct position.
Then insert the needle on the other side, and depress that Tang.
You can now remove wire and connector.

Takes a little practice on the first one. Second one goes a little faster, then you're on your way. Just sounds difficult explained so detailed.

With the individual wires, and their connectors; you can plug each wire in where you want. Connect to the contact pin in the Front Panel header, that you wish.

Trying to cut that connector apart, and leave individual amounts of plug for insulation; may prove unfruitful.
Most of the time the material in-between two of those Molex connectors, is very thin.

Maybe one connector will come away with enough material, maybe not. Most will not.

Also you risk slicing your fingers.

Or you could find a plug connector that fits that group of 7-pins, and transpose the wires over to it.

The front of your computer is the Front Panel.
The area of contact pins on the motherboard, that the Main wires connect to, is the Front Panel header.

Main wires being;
Power On switch wires
Power On LED light wires
HarDDrive activity LED light wires
Reset switch wires, IF used

Since you have the manual, out of curiosity are pins 2 and 4 Power On LED?
1 and 3 are HarDDrive activity LED?
5 and 7 are Reset switch?

For additional questions please post back in Comment.

MX46-633V CONNECTING FRONT USB


I believe you're referring to the AOpen MX46-533V

The Front Panel USB header is Blue in color, and located in-between the white No.3 PCI expansion slot, and bottom edge of the motherboard;

http://www.ebay.com/itm/AOpen-Model-MX46-533V-Socket-478-Desktop-System-Motherboard-/130774572519?pt=Motherboards&hash=item1e72c59de7

With the motherboard in the installed position;
5 pins across the Top row, 4 pins across the Bottom row.

Pins across the Top row are numbered EVEN
Pins across the Bottom row are numbered ODD

Starting on the Left side coming across to the Right, Top row;
Pins 2, 4, 6, 8, and 10

Starting on the Left side coming across to the Right,
Bottom row;
Pins 1, 3, 5, and 7

There are TWO USB connectors supported off of this USB front panel header.

For one of the USB front panel connectors;

A) Pin 1 is USB PWR 0
Goes to the VCC contact pin on the USB connector.

B) Pin 3 is USB_FP_P0-
Goes to the D- pin on the USB connector.
(Data - )

C) Pin 5 is USB_FP_P0+
Goes to the D+ pin on the USB connector
(Data +)

D) Pin 7 is Ground (GND)
Goes to the Ground (GND) pin on the USB connector

E) No pin 9

F) Pin 2 is USB PWR 0

For the other Front Panel USB connector;

A) Pin 2 is USB PWR 0
Goes to the VCC pin on the USB connector

B) Pin 4 is USB_FP_P1-
Goes to the D- pin on the USB connector

C) Pin 6 is USB FP P1+
Goes to the D+ pin on the USB connector

D) Pin 8 is GND

E) Pin 8 is USB_FP_OC0
Leave unconnected

This is more information on a standard USB connector pinout,

http://en.wikipedia.org/wiki/USB

( A USB connector, and a USB plug are not wired the same.
The plug is wired backwards from what a connector is.
Otherwise you would have power and signal going to the wrong pins, and burn the USB Front Panel header out on the motherboard )

AOpen MX46-533V motherboard manual, but it is in Japanese.
May be one in English out there.
The Front Panel header pinout, USB header pinout, etc, is easily cross identified,

I have a ECS A740GM-M Motherboard in an Asus TX-381 case. I can't get the 2 front usb ports to work. What am I not wiring up right?


Make sure you are putting the front usb header connector on the proper USB pin connection on the motherboard. You should see nine pins in 2 rows together. Check the manual that came with the motherboard to find the correct pins location.

Sony walkman NWZ-S754 Recharge is through computer - but can I recharge it via mains or in car.


Yes you can charge your player through main. All you need is a converter which connects to the usb cable to the plug. They are available in the market so you will need to look for it. Or you may find it at any electronic store.

I'm installing a card reader that has 5 wire connector tto the mb. The old card reader has a 7 wire connector that fits the mb. Its an Asus m2n68-vm. Thanks


These card readers normally fit the auxiliary USB socket on the motherboard. They usually take up all nine pins, four on one row and five on the other with a 10 socket plug. One pin missing on the end of a row.Such card readers have an additional external USB port as well as card reader slots. If it is just a straight five pin plug but with four wires it just fits over one side of the nine pin USB socket on the motherboard. The black wire goes at the end with the missing pin.

Extra USB connection


Hi kalimm,

Your motherboard does in fact have special connectors just for these internal USB ports. These are often called "USB headers".

Based on the manual for the board (which can be found here [LINK]), two of these are located on the bottom edge of the board, below the three PCI slots. These are labeled "USB78" and "USB56" and have nine pins in them, which should match the connector that leads to your case's USB ports. Use of these ports is described in detail on Page "1-25" of the manual and I'd strongly recommend reading through this section to verify that things match up properly.

If you need anything else, please let me know!
